Turn Signal Flasher Build

Building a crude turn signal flashing system using momentary switches.

[@user-nd8he3hp2g]

Great explanation. I was able to fix the blinker lights on my motorcycle because of your clear no nonsense, no endless babbling video. Great job thanks

[@PaulPomerleau]

Glad I could help. Ride safe.

[@shelroutdoors]

Thanks for the simple explanation. I am putting safety flashers on an old farm tractor using LED rated 2 wire motorcycle flasher got the job done nicely. Thanks for sharing.

[@pixeluminous]

Great example of the turn signal system. Clear and easy to understand unlike so many other how to's. Thank you.

[@danielbutcher3305]

Thank you so much Paul. I've been struggling to wire turn signals on my ebike today. Your video has made it easy to see where I was going wrong. It was the grounding part at the end.

[@kyleperry8844]

Most helpful video I've seen on turn signals!!

[@Mumbles-iz7tl]

That's how you make a video! Straight to the point, clear and basic. Thanks for the help.

[@W4FFL3S]

Awesome video! Just what I was looking for. I just bought a bike that someone had messed up the wiring and the switch is no longer available. This will definitely help me make an aftermarket system. Thanks!

[@smileyespinoza192]

Thank you so much Paul. Your simple explanation of rewiring turn signals with the relay really helped tremendously. Now I can work on other things ;)

[@billmcroberts6566]

Simple, clear, and accurate.

[@lanceroark6386]

AMAZING!!!! The brevity of this video makes it the most superior video I’ve watched on the topic. And the only I’ve watched. The others bored me into closing the video.

[@byronmorris2946]

U just simplified something that's made me angry for years. Thanks u just made my LIFE easier

[@PaulPomerleau]

It seems I can't comment to peoples comments on this video. This just started and only on this video so far. I don't know why. I will try to figure it out and get back to those asking questions. Stephen Craig - I would think your battery is not strong enough to activate the relay. Try a stronger battery or put a charger on it at the same time.

[@ff516]

This is all clear but why not also mention the warning light wiring (one single bulb)? That's what I was looking and waiting for. I own a Suzuki GS 500 K6 (2006). Everything works fine, I'm just curious to understand how this "turn signal warning light" is connected. There must be something I fail to understand checking the wiring diagram.

[@corybuehn3192]

Best video on here to explain this for dummies. Thanks

[@mitchwilldoit9299]

This was a very simple video even for me. I am using it to put turn signals on my golf cart. it worked like you said, but my flasher wouldn't flash. I will try another. suggestions ????

Thank you for this video. Easy to understand

[@jons.1002]

Thank you for the very informative video. Now I can make my motorcycle street legal here in California :)

[@caseyhunsdon3835]

My question is, how would I wire this if I was using one switch, say the original turn signal switch on my bike? would the one wire coming out of my flasher go to the switch, then from the switch I would run a left and right power wire to the lights, then ground the lights? I think I have it figured out by drawing my own diagram. but not sure? this seems very simple. I cant find the original wiring for the turn signals on my bike, it didn't have any turn signals when I bought it but had them at one point.so I figured it would be easier to use the original switch (found that LOL) and just rewire new turn signals.

[@PaulPomerleau]

Yes you have it exactly right. Wire the output of the flasher to the common connector of your switch and then the 2 outputs will go to the left or right side lights. This will direct the 12 volts to the correct lights.

[@caseyhunsdon3835]

Paul Pomerleau Many thanks to you!! great Video!

[@Oogzie]

by far best video!!

[@maggie1767]

Thank you very much! Exactly what I was looking for and was to the point and very easy to follow!

[@Tifford1]

I have a 67 mili amp drain and it's coming from my hazards. When I pull the two prong relay out the drain stops. All my signals, hazards, marker and head lights work fine. What steps would you do to find the parasitic electrical draw?

[@PaulPomerleau]

Troubleshooting this type of symptom is always difficult. Depending on the vehicle it could be using a Canbus system to activate your lights which uses low voltage communication between circuit boards and not just a straight 12 volt signal. This could be normal for your vehicle. But if it is not then it may be corrosion within the circuit. Either inside the relay itself or inside the bulb sockets, or the grounding wires. It is very difficult to say with the info that I have.

[@fredymora1793]

Muy Didáctico. Muchas Gracias. Una Pregunta: ¿Cómo sería el Diseño con flasher de 3 Contactos? :::>Very didactic. Thank You So Much. One question: What would the design with flasher 3 Contacts?

[@PaulPomerleau]

Fredy Mora Usually a 3 pin relay is an electronic version with a tiny circuit board. One pin will be battery, the other ground and the third is the output to the lights. This way the flash rate will be the same no matter how many lights you put on the system.

[@fredymora1793]

+Paul Pomerleau I found this: X = Battery (Power Input), L = Load (Lamp Output), P = Pilot ( Indicator Lamp).

[@PaulPomerleau]

+Fredy Mora That is what is considered an "isolater". You would add that to the existing turn signal in order to add more lights so it will not interfere with the existing lights. For example, if you were to put a trailer on your vehicle, or adding LED lights, this keeps everything separate so there is no interference and everything will work independently. Hope this helps.

[@stereopolice]

Needs to be a fuse in the circuit. Thanks for the vid.

[@bikesmith]

Another great, simple, clear video. Cheers!

[@orlandoquirante2157]

thnks boss your the best man to demonstrate and i easy to understand.

[@jamieramsay8784]

lost at buss switch,? norm open norm closed simulated turn signal???? is buss norm open turn.?

[@paulparker2322]

Great video, how would you wire a hazard switch to this to make all of the indicators flash at the same time?

[@bradleygreer9211]

Great video sir I really liked it and it really really help me to run blinkers for my golf cart thanks

[@carolinestevenson5696]

Great video. Very helpful

[@COMB0RICO]

Thanks from Texas.

[@jasonhernandez6291]

My last question would be if I would y split from the flasher relay ..looks like need two buttons one for left other for right ? I thinks that way to go and y split the ground to .. I think that makes sense.

[@PaulPomerleau]

Emprez hernandez The output of the flasher could be split and go to each switch. Then the other side of the switch will split to the lights on the left or the right (front and back) then ground the other side of the lights. That would work too.

[@Wickedsi73]

Just wondering I have momentary switches that are two prong. So there for would I run the positive in to the switches (splitting From the relay) then out to the lights and still ground the lights the same? I'm trying to get turn signals on my motor cycle. Also would I need a fuse?

[@Wickedsi73]

Wicked Si Figured it out. I answered my own question. Thanks for the awesome video! Now I have signals on my motorcycle! Watch out people on the side walk here i come! :D

[@Wickedsi73]

Wicked Si I had them working on my bike no problem. Today I drove it and got about three blocks and the battery is completely dead. Do i not keep them connected to the battery???

[@mikebaroz]

Very good explaination. Fixind an old DR650 1995..

[@SolarReturn1966]

Great video!Can you operate both lights at the same time by any chance? Also, I would like to make this except I want to use a switch for the left and right turn signals and add hazards on a four light system. Any suggestions on what type of switches I need and what wiring diagram to use? Any information would be greatly appreciated! Thanks in advance! Best regards!

[@PaulPomerleau]

There are several ways to do this. You can either use momentary switches that you have to hold to make the lights flash, or use push on/push off switches that you can activate and then press them again to turn them off. Then a double pole push on/push off switch for the hazard lights.

[@SolarReturn1966]

+Paul Pomerleau Thanks for the fast reply Paul! Great information here! One more quick question if I may. I'm wanting to put this together but I want to use led marker lights for this project I'm building. Would I need to use one of those LED flashers? Or could I just keep it simple with the two prong flasher that your using. My project isn't going to have any other loads on the circuit, just the load from the other led marker lights and nothing else. I've subscribed to your channel. I appreciate you my friend! Take care!

[@PaulPomerleau]

The LED lights won't draw enough current to make the simple 2 prong flasher operate. You will probably need to get an electronic flasher. It will have 3 prongs, a positive, a negative and an output that will go to the lights. This way it will always flash at the same rate no matter how many lights are attached to it and not rely on the heat from the current. Any automotive store will carry this as people have to change the old one in their cars when they add a trailer.

[@SolarReturn1966]

+Paul Pomerleau Thanks for the information my friend! I checked out your website and will be doing business with you in the future. Till then, Best Regards!

[@PaulPomerleau]

The 2 pin flasher relies on heat from current to flash, the more bulbs the more current and the faster it will flash. The 3 pin unit typically has a pin for ground, another for battery +, and the third pin is for the flashing out. It is a fixed rate so it can be used for LED's and other lights and will flash at a constant rate.

[@yavanochi]

Clean and clear explanation .Thanks

[@Fresh-Tactics]

Paul, great video. I am wondering if I can ground my signals to the frame?

[@PaulPomerleau]

+Wilie Kent Of course. Make sure it is a good clean point. If it doesn't work, that area may be insulated from the frame and you will have to find another area. A meter will let you know if the area is a good ground. Good luck.

[@mohdayman3403]

thank you for this video i able redo my wiring more confidently

[@fad88s]

very helpful video, i have a question, is there anyway that i can do so the momentary button became like push on/push off button so you don't have to keep pressing it when you want it to flash? thanks!

[@PaulPomerleau]

+fadli afdi You will now have to incorporate a circuit board system into the switches. It is very easy and available from various companies. Some places like (SDC) SignalDynamics.com has various modules to do different things. Look them up, I am sure they will have something that you are looking for. There are other companies as well, a Google search will find some in your area.

[@mc-mg8xu]

What happen if u had both switches down will it still work

[@PaulPomerleau]

copper Gray Yes, this is how they make the hazard lights work, all lights flashing at the same time.

[@jakobsinamon1683]

Paul Pomerleau I hooked it up just how you did and it still doesn't blink

[@mc-mg8xu]

the bulbs might not be pulling enough amp to flash but if it is electronic flasher it should blink

[@jakobsinamon1683]

1973C10 1965Elcamino. they are brand new led lights. do I need a bigger flasher?

[@42luke93]

What wiring to use for this with 8aa batteries

[@PaulPomerleau]

There are usually 2 signal lights on at the same time (front & back). I would use minimum 16 gauge wire, but 14 gauge is better. Also I don't think AA batteries will have the current needed to operate this type of flasher. You will probably need an electronic flasher.

[@42luke93]

@@PaulPomerleau I got a flasher relay (3-pin) in auto zone. I hooked it up with test clip wire and it works. So I will use 14-16 gague wire then. I think I have 18 gague lamp wire lying around though.

[@PaulPomerleau]

Hmmm... I didn't know that. I had a 50/50 chance. Thanks for letting me know.

[@victor7261]

Hello, I have a road king, and my left turn signal is not flashing, it just stays on. both the front and the back left signals have the same problem. is it a fuze? or do i have to change the whole harness?

[@PaulPomerleau]

silencio azul Wow, this is a tough one. Just to clarify what is happening on your bike, when you are riding all your signal lights are off, when you try to signal left your front and rear left lights come on and stay on (no flash). Are your right side lights working ok? I doubt it would be a fuse. Remove both lights on the left and using a test light see if the 12 volts is turning off and on. Also check the ground from the bulb socket and make sure it is good. Check the flasher relay as well, that is about the simplest things to check first. I am not very familiar with Harley, they may have a circuit board that controls the signals in which case it won't be as simple as what is in my video. Good luck with this.

[@victor7261]

Thank you Paul, I will apply this procedures. Hopefully I won't have to go to the dealership and pay and arm and a leg.

[@kekothemasteraxzero532]

Sir,thank you for making it so simple...you really helped me :D

[@juanochoa5077]

I would like to ask you a question, from where would I run the other 2 lights? (Front/Back)

[@PaulPomerleau]

+Juan Ochoa On the end of the green and yellow alligator clips where they attach to one of the white wires going to the light bulb, you could attach the second bulb wire there, so the power would go to both sets of lights (front & back). This particular flasher will flash a bit faster since we are now drawing twice as much power. You could use an upgraded electronic flasher if you want to have constant speed and additional lights.

[@mc-mg8xu]

Thank u because I'm trying to build a flasher for my golf cart by the way cool video

[@jasonhernandez6291]

I love this great tutorial I just had a question what kind of toggle switch can i use to give that fuction of bein a able to turn left and right ? Thanks if u can help.

[@PaulPomerleau]

This circuit is designed to use momentary switches where you have to hold the button to flash and release it to stop. I did this because my buddy had these type of switches on his motorcycle handlebars but thought he could not have turn signals with those types of switches. So I did this video to show him that he could.

[@AkikoMakiOfficial]

Thank you so much for this video! I am looking to hook up both front and rear turn signals for my motorized bike, this information may be just what I was looking for and if it isn't I may just be a little bit closer to making things happen when I figure out all the extra details. Thank you again. ( ^_^ )

[@waynecreech]

gReen for right and yeLlow for left is pretty common... but it all works :)

[@crawfordoverton3299]

my question didn't use all prongs on flasher ? or did you ?

[@PaulPomerleau]

The type of flasher that I used has 2 prongs and I used them both.

[@burtoe]

nice and simple explanation. thanks!

[@lonewolfvlogix6335]

Very helpful

[@isaiahdaquioag497]

What if my battery only has a positive and negative with no ground? Can i just ground a wire to some where else?

[@PaulPomerleau]

+Isaiah Daquioag The negative side of a battery is the ground.

[@isaiahdaquioag497]

+Paul Pomerleau oh nvm i seen your vid a second time, i thought there was 2 grounds on your battery, but i only see 1 each of positive and negative, thanks though! And good vid, something i can understand

[@isaiahdaquioag497]

+Paul Pomerleau what if i got switches to control the signal, i got the lights flashing but one side stays flashing but doesnt turn off

[@PaulPomerleau]

+Isaiah Daquioag In my video I am using momentary switches, so once you let go the power stops. It sounds like you put in an on/off switch. If you did that and pushed the switch to on, then it will stay on until you push it to off. This circuit is meant for momentary switches.

[@isaiahdaquioag497]

+Paul Pomerleau oh ok thanks tho!

[@michaelcee8348]

good. much thanks

[@mobilelegendsgameplay8653]

thank u for the reminders

[@TheCrazyfool27]

What would be the difference if my flasher has 3 prongs?

[@PaulPomerleau]

That depends what is written beside each prong. A "B" or "+" is your battery positive. An "L" is load meaning your lights going through your signal switch. A "-" is ground or battery negative. A "P" is for an indicator light on the dash. Yours may differ depending on who makes it and from what country, but usually it is stamped on the flasher unit or on the packaging.

[@TheCrazyfool27]

Paul Pomerleau thanks for insight and quick reply

[@paddymccune8512]

[@jamesclarkson578]

where do you get that battery

[@PaulPomerleau]

This battery happens to be from my weed trimmer. They are the same as ones in a house alarm system. You can get them at battery shops such as Interstate Battery, Total Battery, Batteries Plus... places like that.

[@kinkankero]

Thanks amigo. What is the relay that you use?

[@PaulPomerleau]

Christian Aguilar I bought it at the auto store just for this video, it was the cheapest one I could find, I don't think it had a name, I paid less than $2 for it. any flasher relay will work.

[@LocalScenery]

So nice, thanks a lot!

[@kopper248]

Mine just works if i enable both lamps?

[@PaulPomerleau]

The flasher uses current to heat a metal spring to open the circuit, either you will need lights that draw more current or your battery is not strong enough to deliver the current. You can also try an electronic flasher that works using a circuit board inside that will make the lights flash no matter what kind. Hope this helps.

[@kopper248]

@@PaulPomerleau That makes sense, Thanks :D

[@tristan6509]

no relays?

[@PaulPomerleau]

Relays are only needed if the lights are drawing more power than the switches can handle. In this case no relay is needed. If I wanted to hook up an air horn for a pulsing alarm then I would need a relay because the switch would eventually burn out not being able to handle all the power.

[@nischaltam]

tysm. u helped me so much

[@o0Orange]

Why it flashes faster when one bulb is out in a cat

[@PaulPomerleau]

o0Orange The inexpensive flashers work using current that heats a piece of metal that eventually opens the contacts until it cools again then it closes the contacts and the cycle starts again. So by adding more bulbs, or bigger bulbs the flasher will operate differently. This is why when you put a trailer on a car the lights flash really fast, or by changing the bulbs to LED's they may not flash at all... it's all about the current. One possible way to fix this is to change the flasher module for a better one, one that can regulate the speed of the flash no matter the type of bulb. This is usually what you have to do when adding a trailer to a car. The wiring connections that I show in my video remains the same.

[@o0Orange]

thank you so much for you infos. that really helps

[@donaldcampbell7894]

that’s nice but yellow was always left and green is right. Just saying

[@PaulPomerleau]

Yup, you are right. My bad.

[@SpiritsoftheWolf]

i made that long time ago in 2006 on my ford econoline van, works great with tractor starter buttons, 1st on was done on my 88 econoline van and i did it to my 91 econoline, and i got them on my gator cx, works best with automatic transmissions, not in manual transmission as you have to use the clutch, here's the video of my turn signals on the floor in my 91 econoline van kzbin.info/www/bejne/gaKsYX-agbWJebs

[@bentley6028]

would this work with a switch concept like an I'm off switch

[@PaulPomerleau]

Yes it would, but like a light switch you would press up to turn on the signal lights and they would stay on until you pressed the switch down to turn them off. If you pushed both switches into the on position then both sides would flash like hazard lights.

[@bentley6028]

Oh ok would I need a resistor if I'm doing leds

[@PaulPomerleau]

The flasher in my video is the very basic model and requires current to operate. LED's don't generate enough current. So you will either need resistors or get an electronic flasher which has a circuit board inside to regulate the flashing, then it doesn't matter what lights you use.

[@bentley6028]

oh ok I have some just wasn't sure does it matter where they would go on the harness or no

[@PaulPomerleau]

Normally they would be near the bulb itself, but I guess anywhere on the wire between the bulb and the switch would be the same. Also the resistors are going to have to be high power ones about 10 watts each. The small 1/4 watt resistors will burn out or simply won't work if you are going to use the basic flasher module that requires higher current to operate.
