Top man. Top video. 5*****s from me. No background banging music. No fast talking or foreign accent. Just plain English explained thoroughly. Well he is English. Well done Andy.

[@StruggleGarage]

Who the hell would dislike this video? Amazing explanation!

[@wicked_digger]

I personally did not dislike it. However, i don't like how he did not wire in a switch. The way he did it here a flasher will work 100% of the time. Constant power, no ground to switch to be able to control it, turn it on/off

[@davidlane728]

Thanks Andy for a very quick response. I will go shopping tomorrow and give you feedback after installing the relay..

Thank you so much for the video. I've now got a game plan to make my own turn signal lighting harness for my John Deere Gator RSX860M. That was going to cost me $750 to have the factory harness and lights installed at my dealer. The low cost option was to buy a $420 factory wiring harness and switch, purchase my own lights and install myself. I bet I can buy all the parts and make my own for under $100! Great and inspiring tutorial.

thanks for showing basics of relays. I'm seeing a lot of really inexpensive 2 pin relays on the market, with adjustable rate, usually 50 - 200 c/min

[@jdl7211]

Great video that answered some of my questions especially about the load and speed of the flash. I'm looking for a way to make a 12 volt LED strip flash using this same idea however not on a vehicle.

[@AndyMechanic]

+JD L An electronic flasher relay will do that - it's not load sensitive

[@dunckeith]

Great vid, helped me test some relays

[@PBS-nm1uu]

great presentation

[@genericdude6551]

Newer vehicles don't have a replaceable flasher relay (like my 2014 Xterra). So your only other options are loading resistors or get CANBUS rated LEDs for your car/SUV/truck. The CANBUS LEDs have circuitry that pulls normal halogen/incandescent current which fools the cars electronics into thinking you are using halogen/incandescent bulbs. Not all vehicles will work properly with the CANBUS rated LEDs so you may have to go with loading resistors. The downsides to the loading resistors is heat dissipation and if the LED goes bad the car's electronics will think the LED is still good because the loading resistors are still pulling the same amount of current. That's why you should check your lighting on a regular basis - but it's obvious that a lot of people won't do that.

[@AndyMechanic]

Very useful info, thanks for your post. Cheers Andy

[@genericdude6551]

@@AndyMechanic I just got a pair of CANBUS LEDs (CK socket type) for my front turn signal lights on my 2014 Xterra and they work great. No hyperflash when you install the CANBUS LEDs in both the front and rear. CANBUS LEDs make for a cleaner install (compared to resistor kits) but they don't fix hyperflash on all vehicles (according to my research).

[@vulcan-900bobber7]

Hi Andy I've installed LED to my 2007 Vulcan and the rear is all good with 2 wire setup but the front which are 3wire stay on but indicate when you activate switch so you have both lights on with one blinking. I also installed aftermarket relay for LED lights which is a 2pin same as the original.

[@joelopez9225]

Like the basics, good refresher, but you probably might add running lights like ones found on my old 1983 kawasaki 750 ltd. The reason I feel it would be beneficial is the front and rear running lights the turn signals share the same single filament bulb and a 2 conductor flaher. This would help those whom don't understand how that one filament can flash when the lights are on, trouble shoot more effectively. So it is my opinion. If you would include the ignition switch and turn signal switch and maybe the separate two conductor hazard flasher could be even more beneficial for understanding what real world scenarios, such as chasing a bad wire/connector or multifunctional switch like in my 04 Ford f350 can greatly complicate simple circuits such as a flasher

[@vernboulet1015]

working on a project vehicle without any signals (yet) Do you have a vid on how to wire in a complete system (using a three prong electronic flasher) or other. This vid showed how to get a flash, but not how to get it to flash left or right through a three position switch ie: on - off - on (like on a cycle)

[@AndyMechanic]

Hi, ah, that's easy. The output from the relay that you have going to the bulb. That's the feed to the left/right switch. Then from the switch just run the power feed, in parallel, to each of your indicator bulbs. The other wire from each bulb goes to ground. Hope this helps Cheers Andy

[@hannachoi7161]

Great video! I noticed that the light bulb's connection to the LED relay was accidentally connected at the 39, not the 39a (around time 9:30 in the video). That might be why the LED one didn't work

[@johnmcmahon3259]

Hi, I'm wanting to try this but my motorbike has hazard lights too. My bike is a Honda and the original relay (for filament bulbs) has 4 pins. Would my hazard lights still work with a 3 pin universal relay? And I have an led 2 pin relay (adjustable flash speed) would my hazards still work on a 2 pin relay? Thanks for a great video 👍

[@clintonbroadus9389]

This is super helpful!!! I've recently installed LED's on all the exterior flasher bulbs on my 86 GMC K1500 they worked good with the bulbs installed for all the rear lights then when I installed the front flasher LED bulbs they all flashed very slow. I'm assuming its either a problem with my relay or the load is somehow being blocked from LEDs between the front or back. I was going to try load resistors to even out the ammount of power going to the LED's. now that I've watched your video I think the flasher relays may be more of the problem though.

[@ericshepherd9407]

So an electronic flasher 3 pin will work on front and rear and mirror turn signals ? What about running lights? I have a 2004 EZGO TXT:Marathon golf cart. Any thoughts….Thank You Andy!

Hi Andy, Today I picked up four much brighter Navra LED amber blinker lights and my new CF14JL-02 three pin electronic relay. Sadly I can't make the system blink yet. Changing this relay back to the old non electronic 3 pin relay made all the lights work on Hazard but they still don't blink. Same happens when either left or right indicator is selected and just that side comes on and doesn't blink. Question, Are there different ratings in electronic relays? Should I have used a two pin instead? Many thanks for your help. David.

[@tonycruise]

same thing

[@AndyMechanic]

Hi David, a true electronic type relay shouldn't be dependent on load to trigger flashing unlike the old bimetalic mechanical type. However, given the relay works correctly when actuating all the indicator lamps (hazard mode) then I would suggest maybe swapping the relay for a lower wattage one - the pin layout must be correct as the relay works when under a higher load. Hope this is of help Andy

[@tonycruise]

so i plugged in everything on an older toyota, 81 to be exact and it does not flash my hazards or turn signals....do i have to do some extra wiring for ground? i know my fuses are good and everything else because it still works on the old relay but not the electronic relay @@AndyMechanic

Great video! A '?'.. I need to replace an existing faulty 12v 2 prong relay that's malfunctioning on a 64 vw beetle (no emergency flasher in 64, it's just for turn signals). Was told I should go to the 3 prong (newer type) so the pin 31 can go to a grd so it works properly. Would this be true? Thanks for any feedback!

Great job fam 💪 well done explanation 👏👏

[@marcarmstrong2249]

Hi Andy loved the video, can you tell me what size flasher I would need two pin , to run indicators at 10 watts per bulb ? Regards Marc

[@AndyMechanic]

Hi Mark, will that just be one indicator front & one rear? No side mounted indicators? If so then just one that works with a 20 Watt draw (which is very low). You may be better getting an electronic flasher relay instead due to the low current draw. Hope this helps. Cheers Andy

[@marcarmstrong2249]

Andy Mechanic it’s going to be two on either side Andy front and rear , iv wired everything up but it’s flashing a bit too quickly?

[@AndyMechanic]

Ah, okay, if it's flashing too fast than the current draw is too high for the flasher relay you have. You'll either need to get lower wattage bulbs or a higher rated relay or an electronic relay (electronic type relays flash at a set Hz independent of bulb wattage unlike the old bimetal strip type relays.

[@marcarmstrong2249]

Andy Mechanic ok thanks very much Andy keep up the great videos my friend

[@worldcollections2839]

listen Sir : I have a relay calls Hella : it has 4 pins (31/49/49a/c2) what is the C2 exactly for and how to wire it ? I could wire one or two lamps without using the C2 pin ... but what it is used for ? I will be thankful with your answer

[@Ni5ei]

Thanks for the info. But this is only controlling 1 set of bulbs. So how can 1 relay control both left and right turn signals?

Via the switch next to the steering wheel or on the handlebars if a motorcycle. Cheers Andy

[@Ni5ei]

@@AndyMechanic [edit] Oh wait I get it now! The left/off/right switch comes AFTER the relay and determines where the power coming from the relay is going to.

[@dannyarevalo4799]

Hi Andy. I have a question, is it posible to wire LED flashing lights without a switch and have them come on everytime the brakes are applied on a Harley Davidson? Thank you in advance for your response.

[@AndyMechanic]

Hi Danny, yes, should be easy enough. Though the circuitry to make the LED lights flash would ideally need to be integral to the LED lights so a bit of research needed. However, have you considered the legality of such additional lights? A brake light both in the UK & here in NZ must illuminate when a brake is applied (motorcycle front or rear) & must maintain a steady output whilst the brake is applied. In the US they often use the same light to indicate that the vehicle is turning - by flashing the brake light. What you propose may well cause confusion to those driving vehicles behind you, implying that you intend to turn. Hope this is of help. Cheers Andy

Andy, 1991 Honda Africa Twin. Stock turn signals. I notice in cold weather when I activate the turn signal there is a significant delay before the signal starts flashing. Works normal in warm weather with instant flashing. Would you say bad relay?

[@AndyMechanic]

Hi Mike, Yes, I'd start there. They use a bi-metalic strip type relays which will take longer to warm up in cold weather - beat option is to swap it for an electronic one - they just plug straight in. Take your oodles relay with you so they match up the correct one & make a note of the wattage of each flasher bulb - will be in your service manual under electrical specifications Cheers Andy

Would it be possible to wire in a conventional relay just to operate right side indicators from my indicator stalk??Thanks.

[@cjc1216]

So I'm a little confused, now the relay basically intermittently interrupts the circuit to cause the bulbs to flash if It stays solid is it because there is too much wattage going into the bulbs or not enough ?

Not enough and as a result the bi-metalic strip does not heat sufficiency to deflect & break the circuit. Hope this helps. Cheers Andy
