How to Wire Turn Signals | Car Directionals | Hazard Switch | NO RELAYS! |

This is how I would wire an LED turn signal indicator circuit without using relays. Some people also call these lights directionals or blinkers ("Blinkahs" in Boston). This circuit diagram can be used for a hotrod, car, truck, motorcycle, ATV, dirt bike, side by side, or whatever kind of vehicle needs a left and right turn signal. It is a 12 volt circuit and it is meant to use 1157 / 2057 style LED bulbs.
Below is a list of the LED turn signal flashers, fuses & fuse holders, the 1157 / 2057 style bulb sockets, the LED bulbs, the 3 way toggle switch, and the single throw double pole switch that I used to make the entire turn signal circuit work properly.
Items used in the turn signal circuit (You may not need to buy in these quantities, but I did.)

Great information but how did you find silent flasher's? All the flasher's I've found are typically specialized relays with the circuitry to make it work.

Thank you very much for your videos. I'm a hobbyist. I've watched so many videos to learn how to wire and all left me with questions. Until I've watched yours. You have a talent for explaining how things work (even for the beginners).

I appreciate that you use the term “flasher.” Even though “they” say “relay,” this just throws more confusion onto folks who ARE trying to learn about vehicle electrical systems, IMHO.

YES! I’m glad you noticed that. It’s super easy to slip back into calling it a “turn sign relay” or something, but I do my best to avoid that and try to have it digestible by someone with basic automotive knowledge. Thank you for watching and the feedback. It’s appreciated!

In the Old Days, When A Bulb burned out, It stopped flashing. Like a Resetable Circuit Breaker. New Flashers(Electronic) Do a Quick Flash when a Bulb burns out. Resistance Added to LED's can Make them Work. When Outdoor Led Flood lights came out, The Resistance(Load)was So Low, wouldn't Work With Motion Detectors, I would Add A Small Relay So the Resistance of the Coil was enought to make them Work correctly. Didn't use Relay Contacts, Just the Coil to increase the Load, Worked Good.

[@AztecWarrior69]

You don't need 2 different flashers to do this. Just look at most vehicles, they only have one flasher. As far as the hazards needing to be useable when car is off, that's just a matter of running the power through either the ignition or direct and you use a DPDT switch instead of the DPST. Add two diodes. Add four more diodes if you intend to be able to use the turn signals as brakes.

[@bernardocisneros4402]

He's not trying to make it rocket science. He's breaking it down so everyone can understand. Can you please post a link to a video that shows how to make this with 1 flasher, 1 DPDT switch, and 2 diodes?

[@TexasEngineer]

You may have a back feed problem. If the ignition is off, the hazards are on and a turn signal is on, you might have power on your ignition circuit. This would require a diode unless your LED flasher incorporates a diode. This should have been explained.

[@The_Beard_Barista]

Hello ! You make it looks very simple, my question is, if the hazard key is on, and I decide to activate the right or left signal switch, should it works ? Or should I desactivate the hazard switch before ?

Motorcycles don't use a second relay for flasher. They use a dpdt switch, but for it to work, the ignition needs to be ON or in the Hazzard/acc position. It's a simpler circuit, but the ignition or acc needs to be on. 👍👍

Great video, explanation of the circuit was fantastic. I am rewiring a old car that was 6 volt to a 12 volt system and this circuit is exactly what I was looking for except for 1 thing. I have a single bulb in the dash for the indicator with no emergency flasher so where does that bulb get its power from so it flashes for both right or left turn?

[@manningcustom]

I am trying to improve the wiring on my karmann ghia. I get 13.5v at the battery and the generator. but in the front of the car I only get 10v. so my lights are very dim. I am going to rewire it one circuit at time using your videos. FANTAST by the way. Because I have some issues would it be dumb to not ground each circuit on the car and run a wire back to the fuse area? That way if there is an issue somewhere grounding the battery/ motor/ chassis at least my lights will be 100% when I can get higher voltage to the front of the car. (motor in the back) I really appreciate these videos.

[@WiringRescue]

Hi Michael! You can absolutely run ground wires all the way to a fuse panel or ground distribution block. That being said, that is how British cars were wired for about 50 years and they are well hated for overly complex wiring! If I were there helping you out, I’d make sure the chassis and engine were both grounded well from the battery, and then ground all the lights right to the chassis. You may have to clean paint/undercoating off of the chassis to get hood grounds, but it is a lot less wire to do it this way. Also - old light sockets are a common cause of problems. Don’t be afraid to buy brand new bulb sockets for your bulbs so they have a good, clean connection to the bulbs. Good luck! I’m rooting for you!

[@manningcustom]

@@WiringRescue thanks for the advise. I'll start there

[@Dubst3pT3ch]

You may want to check and clean your light switches as well. Older cars tend to run full current through their switches which can cause issues. I know my mk1 Jetta has issues with low voltage high beam circuits because of the power going through the stalk instead of a relay.

[@Christopher-yh5lh]

Huge question: I'm trying to find a relay to add a blinker function to a taillight and headlight of a KRX1000 UTV. There has to be a relay I could supply power to that has enough function to allow the lights to flash regardless to weather or not the brake is on or off / lights are on or off... Any thoughts? I would like to tie this directly into the factory wiring harness.

[@HAMMER_2.2]

Do these LED flashers draw any current when the Signals/ Hazard switches are turned off? I'm thinking of the Hazard flasher in particular ,being connected to constant 12v. Since the LED flashers aren't Load Sensing, I assume they are always On (Always flashing)? If so, any chance they pull current before the Hazard switch directs the flashing 12v signal to the Marker lights? Hope that makes sense!

[@ElectraJetProp]

No, they don't because the circuit is open, not complete. The flasher has 12V coming in, but the three-way switch is in the middle position (open), that way the circuit is incomplete and thus no current flow. Another way to see it is a bulb that is connected to battery positive but not grounded: you have no complete circuit and no current flow. Much like those horn circuits with two wires going into the horn diaphragm because unlike most other automotive components, they are ground-switched instead of battery-positive switched.

[@MothBird]

Is there a way to wire a hazard switch in without a double pole single throw? Could you wire it with spst and diodes?

[@ElectraJetProp]

You can: you'll need a distribution block from the hazard flasher load side splitting to both halves of the turn signal lights. Remember that some installations have a fender turn signal light as well, and most will have a dash indicator as well, so you'll need to keep that in mind when calculating your loads.

What Gauge Wiring Do You Use In Your Videos? 10 Gauge?

[@WiringRescue]

The wire and fuse sizes greatly depend on which components you are using, and what amperage draw they have. I made a video about it actually - check it out kzbin.info/www/bejne/e5ndf2mLmdOghqM

Just saw this video. Would you be able to help me with a project? That revolves around a wiring harness. And branches into the brakes of light system

Can you put the switch between the power supply and led flasher?

[@WiringRescue]

You could, as long as your switch is rated for the proper amperage for the circuit. If not, you’ll burn out the switch for sure. Maybe even light the switch on fire.

For this set up using turn signals only not hazards were you using 16 gauge wires ?

[@mainemagnetfishing]

Could you do a video like this one showing how to do this setup with headlights taillights and brake lights I am building a motorized bike but can't find a good video showing how to do all the light wiring

[@WiringRescue]

Check out my wiring playlist. I actually have a few videos that should be what you are looking for. Good luck with your project!
