How to Add Hazard Lights / 4 Way Flashers to a Turn Signal Circuit. Hotrods | Cars | Motorcycles

In this video, I show you how I would wire hazard lights (4-way flashers) into an existing turn signal circuit. This could be used for a hotrod, car, truck, motorcycle, ATV, dirt bike, side by side, go cart, or whatever kind of vehicle needs working hazard lights. There are many different methods of wiring 4 way Flashers, Hazards, and Turn Signals, but I prefer to wire them as I describe in the video because I feel like it is a safest method. Below is a list of the relays, the non-LED turn signal flasher, fuses, the incandescent 1157-style bulbs, 1157 style bulb sockets, and the 3 way toggle switch I used to make the entire circuit work properly.

[@ChiruStone]

Hey hi! Thanks for all the great videos. So, i have a question that is killing me. Maybe this isnt the right place but i’ll shoot my shot. I have a b250 dodge van, 1984. I have hazards up front, not in the back. All 4 corners for Blinkers work, all grounds clean. Flasher switches are ok. Cables look good ( all power tested). Noone seems to find the problem. Bulbs are ok etc. could you help me with a guess, or even better, a solution. Thanks in advance.

[@WiringRescue]

Make sure you have the correct bulbs. It’s very easy to put the wrong bulbs in and lose functionality. If you are 100000% sure you do, you’ll have to follow the electricity from the flasher to the rear bulbs and see where the flashing stops. Good luck! I’m cheering for you!

[@ChiruStone]

@@WiringRescue thank you for the quicl reply! Y You rule! I actually have signal up till the bulb socket, both for hazard and blinkers. So it has to be the bulb, which is weird cuz i tried other bulbs and also didnt work. But it really comes down to that. I guess 😅 but if it doesnt work than i’ll have to press-depress the stop pedal to emulate them hazards 😂

[@WiringRescue]

@@ChiruStone - haha! It could also be the socket itself - but I’ve seen the wrong bulbs more often than busted sockets. New sockets are cheap and so are bulbs, so you could swap both and cross your fingers! Good luck!

[@kylescott4888]

I think ill add a relay to the Harvard switch, that way it can send power to both signal lights

[@BarneysGarage]

So am currently working on a Peugeot 504 indicator system how ever the single really seems not to respond. Also am using the stoke indicator switch. Any advice?

[@WiringRescue]

You'd have the grab a test light or multimeter to figure out how the factory switch works. Each manufacturer has different functionality built into their switches and you may only need a small part of the factory switch to trigger the relays. The relays control the lights, as seen in the video - So all you have to do is find any kind of functionality in your factory switch that will trigger the relays. If you can come up with a factory wiring diagram for your signal switch, and get it to me, I can probably help you make sense of it.

[@BarneysGarage]

@@WiringRescue thank this actually makes sense didn't think about that.

[@WiringRescue]

@@BarneysGarage - excellent! If you need any help - post it up here and I’ll do my best to assist.

[@kaiser0050]

So if your taillights used the same bulb for brake light operation, running lights, and turn signals how would you wire that up?

[@WiringRescue]

In my opinion, you’d probably want to use at least two bulbs for each side in that scenario. Otherwise you’d lose your turn signal when you pushed your brakes. I’m sure there is a way of doing this though. I’ll give it some thought. It could be a fun challenge.

[@kaiser0050]

@@WiringRescue I only ask because I know a lot of vehicles like mustangs, f150s, Silverado’s etc use the same bulb for all 3. Currently trying to do it to a racetruck 😂 ditched all the factory wiring

[@dickdick999]

Hi there. I do like your wiring videos as they are well done and they fully explain everything. One question. For the hazzard light switch. Could you use a single pole single throw switch with 2 wires to the indicator switch instead of the double pole switch? Just wondering if that would work. Thanks.

[@Bosbulls]

No. Because then when you use the turn signal switch to either side, all the lights will still come on due to the "short" at the single pole switch.

There are two black relays in the video that are connected to each other. One controls the left turn signals. One controls the right turn signals. There is also a flasher, which is often called a "flasher relay" in the automotive world. Thats the round/cylinder shaped thing that is silver in color.

[@freebirdsafety]

Question? I have a ford E350 cube van. all my signals work including the dash indicator light. However, when I hit the hazard lights both front and back drivers are fine. The passenger side only the back hazards work. The front end does not flash and the right-hand indicator light is out. There are only 3 wires to the bulbs ground, running and flash. So, wiring to the bulb isn't an issue. replaced with 3 different bulbs and the same issue. from this video the hazards are set up by either left and or right. If it was a switch issue, the back passenger would be out as well, correct? I am stumped as to wherte to look next. and considering its a van front end, there is NO room under the hood.

[@WiringRescue]

I wonder if your light socket is damaged in some way. if you haven’t done so already, back probe the light socket or a nearby connector with a meter or test light to see if the electricity is making it out through the wires. If not, you’ll have to dig into the opposite end of the wires near the steering column and see if the power is coming out of the switch properly (it probably is). It’s a crappy process, but you basically have to chase the electricity from the bulb back to its source to find out where it is getting lost. I’d bet the issue is somewhere near the bulb socket though. That would be the most common. Also make sure you have the right bulbs in the rear too. I know you said it works, but make sure it’s actually the right one too. The wrong bulb in a different location can cause weird issues too. Good luck! I’m sorry it’s not a super easy solution for you!

[@jaket418]

I’ve been working on a new a project recently and all of its problems are electrical. The hazards work but the blinkers don’t.

Hi Pleasant day I need some help on this video couple question please is the flashing relay is it a 2 pin or 3 pin

[@WiringRescue]

The one used in this video is a two pin.

[@A_Litre_of_Farva]

Wouldn’t it be far simpler to skip the relays and just use 3 flashers? 1 for the signals and the other 2 for left and right Hazzards? Then you can use any simple switch too…?

[@WiringRescue]

There are tons of different ways to wire a circuit. I think what you want is this video though - kzbin.info/www/bejne/q4nMdqKAi9l7n5osi=_rcRVVaJSSfQxLgk because it has the turn signals and hazards without and relays.

[@A_Litre_of_Farva]

This won’t work with brake lights, unless they are separate bulbs from turn signals. You have the front and rear lights hooked together, as did I, and when the brake light switch is activated, it will send power to the front signals, not just the rear. How would you do this to isolate the brake lights?

[@richardyelich4695]

I am running led directional lights .Do I have to go through a relay?

[@WiringRescue]

It depends. Is your switch rated at a high enough amperage to handle the amperage draw of the light bulbs? Are the wires and flasher also rated at a high enough amperage rating for the bulbs you are using? If so - then it should be fine. The only thing to watch out for at that point would be somebody in the future adding regular bulbs in place of LED’s and it burning the circuit. If you have the fuse properly sized though, it will pop the fuse before it burns the wires or switch. Hopefully that made sense. Lol. If not, I can try again.

[@AztecWarrior69_69]

I like this video. Nice. However, never in my 40 years of working with electronics have I ever seen relays being used for turn signals. Basic turn signals. That basic SPDT 20 Amp switch can handle that all on it's own. Removing then will cut down the wiring by 40%. Also the hazard switch can be done by a SPST switch and 2 diodes. Now if you wanna make the hazard button sleek and not so bulky, THEN the relays would make more sense.

It's never a dull moment. LOL

This blue wires that comes from the flasher relay the coming from which number on the flasher relay

thank you

You're welcome

I have almost zero knowledge of electronics and I wanted to learn something by building a simple toy for my kid. I planned to use two groups of three red blinking LEDs each for "turn signals" and three white LEDs for "headlights". I also wanted to add a couple of green blinking LEDs for the signal lights on the "dashboard" when the blinkers are on, and one blue LED for the indicator that the headlights are on. Each group of turn signals would have one switch (single throw), there would be one more for the headlights and maybe one "main" switch for the whole circuit. I also wanted to add one more LED which would be on whenever the main switch is on. So in the last few days I've been browsing youtube for useful tutorials and that's how I found this one. And I like it :). Since I have an issue with my LEDs blinking at different frequencies (and I have no idea why that's happening), I'm now thinking about using relays and making something like you did in this video.

I want to make alternating flashers like a school bus. how is that done?

[@Travelguy_nw]

This was a great tutorial! I have a Polaris rzr with turn signals but no hazard lights. Was there any specific reason for using a double pole switch over a single pole for the 4 way function? Only thing I could think of was amp load?

[@dratilhelvetedotlol]

You can't connect the two white wires in this system together, otherwise you will always have a 4-way flasher.

[@1Martyn1]

What you call a the 3 way switch is actually a 2 way switch. Iy only turns on in one out of 2 directions.

Great Video Dude I'm Planning To Put Something Like This On My Go Kart

[@WiringRescue]

That sounds like an awesome project! Good luck and thanks for watching!

[@AreeVee]

@@WiringRescue Thanks man you're videos are always fun!😉😁

[@royrodriguez5390]

Love all your videos ! I would love to see you make a video with everything put together for lighting. So headlights, turn signals, hazards, high and low dim all in one.

[@WiringRescue]

I will definitely be doing that, I’ve just been doing a bunch of winter prep on my garage recently so I don’t freeze to death this winter! Once that’s done - more videos!

[@fleetwood9142]

I totally agree 👍 👌 super clean electrical live diagrams ..

You familiar with nissan vehicle with hazard switch and flasher units

[@yosoydpfknr2855]

I need this with a headlghts on

[@WiringRescue]

I’ve got a lot of videos that show different varieties of this circuit, but really you just need to have your headlights trigger the relay instead of a switch. Should be very easy.

[@steamy1225]

Now that makes sense . Wasn't sure how the big car manufacturers wired up the hazards to the turn signals . Now I know. Pretty clever.

[@WiringRescue]

This actually Isn’t how all cars are done. This is just how I do it sometimes. There are probably dozens of methods. I’m actually making another video now of another option. So stay tuned!

[@sergiobernal3740]

Can you use a 3 pin flasher ?

[@WiringRescue]

I’m sure it’s possible, though I don’t have a 3 pin flasher handy to test it with. So I unfortunately can’t guide you with directions on how to do it. That is an interesting idea though. I’ll keep that in mind for future videos.

[@danielhunt7691]

Great video . Will help with wiring my series 2a landy. However i have a question. Could only one relay be used. If the relay was wired before the flasher. And the switch was more of a negative swtich.

[@WiringRescue]

Stay tuned - I’m actually working on a video right now that may be even better than what you want! I expect I will have the video live sometime next week. It will (hopefully) be turn signals, parking lights, brake lights and hazards.

[@abhayramesh2410]

What will happen when both turn signal and hazard switch is turned on

[@scratchbuilder101]

I have never binged someone's videos like I have these wiring series vids!!!! So clear and easy to understand!! THANK YOU!!!

[@WiringRescue]

Haha! Thank you! Tell your friends to watch too! I’m glad your enjoying them!
