[@jeramiahrussell-ansbro6573]

hey i was wondering how many amps should go through the swtich to the relay to turn on the headlights i think 5amps should do but i want your opinon on it.

Great Video! I am working on my 1978 Ford Bronco - it had been sitting in a barn for 20 years!

[@b.s.adventures9421]

On older cars it’s a good idea to wire two separate relays down stream of the dimmer. Close to the actual lights. One for the low beam circuit. One for the high beam circuit. You eliminate a lot of the resistance though the hi, low switch itself, the plug on it, the firewall connector, and all the length of small gauge corroded old ass wiring. You’ll get a nice bright light with much less voltage drop. Still a great video on the concept. Nicely displayed.

[@technicalitems731]

So you mean have a relay in same spot as this video? Then add two more right before each headlight?? I appreciate your advice and I'd like to understand what you are talking about?

This is the way. I'm doing my 59 imperial this way. The old harness is still mostly intact but I don't want the heavy load of all 4 headlights going through the factory wiring. Instead I am using the factory wiring to trigger the relays for the new wiring and lights.

Great video, thank you, and congrats. Right now I am rewiring two projects from end to end. An '87 Jeep YJ upgraded to V8 etc. That is mine. The wiring was the worst I have ever seen. Took it out in pieces then threw it all in barrlel. All new made by me. The second is a '74 Karmann Ghia used for the base of a kit car, who knows when owned by my former wife. It has all of the original '74 wiring. Pretty much the same but had to take it apart one at a time to learn what made it tick. A complete rebuild one piece at a time. Thanks again for all of your info. Subbed.

I used a 91 grille in an 85k10, but instead of using just winners for highs. Or outters for lows. (They are single flament headlamps) I hooked the lows up normally. But added a relay from high positive to backfield lows when highs are on. And so I get all four. The rectangle ones that have four. Usually have 2 filaments of 45w on the top ones, (one aims down, one up) and the bottom ones are 50w and are wired to the top aimed up filaments. And of course the round ones or single rectangle ones are wired in a way like a twilight bulb.

I have a 2001 International 9900i semi truck. I was driving in heavy rain Thursday night. I dimmed the lights for oncoming traffic and blue light on dash dimmed slightly but high beams stayed on. They wouldn’t shut off and occasionally the low beams would come on. Now high beams are stuck on. All fuses and relays good. I got a dimmer switch from a Chevy truck brand new at parts store. No one had international switch. One place said they could order it for $160. It’s the same kind of switch as the Chevy switch. The old switch was wired with electrical tape and when I pulled the tape off the wires came off so I didn’t know which one went to which terminal. I put the green wire with constant power in the middle top terminal. I tried switching the yellow and black wires from left to right on the bottom two terminals. I got it so it’s doing the same thing it was. The blue light is dimming, but the high beams are staying on. The driver side headlight when I go to dim it is flickering. The terminal on that light had a problem with it before because it was all green, so I cleaned it up and it worked for a little while. Today I wired a new plug onto it. That didn’t help. It is still doing the same thing. What else could it possibly be?

SoI have a quick question. I thought the reason behind having relays is so you do not have high voltage coming into a switch that can’t handle the power. But looking at your diagram you have power coming from the battery into the switch and then it is going into the relay

[@kman1644]

I really like your setup for the headlight wiring. Could you show how to connect to the ignition switch so that we don't accidently drain the battery? My 2007 ram 1500 headlight circuit is no good and I don't want to replace the TIPM. I want to connect my headlight circuitry outside of the TIPM.

[@WiringRescue]

It could if this is the design you are wanting. It is sort of up to you. If it were me, I’d probably fix the factory wiring harness, unless it was severely damaged or burned or something. The connectors at the headlights often fail on the Firebird style (sealed beam) headlights, so it may be worth diagnosing yours and starting right at the headlights themselves.

[@rodneyenglish2490]

@@WiringRescue thanks I really appreciate the input on my question I’ll definitely diagnose the factory plugs first before I have to do any aftermarket hookups like this great one you have showed here !

[@KymannaGrothaus]

On semis there is a button on the steering wheel that you can press to turn off the headlights there is also a separate button that can be pressed to turn off all the daytime running lights. All lights come back on when you let go of their respective buttons. I would like to install those buttons on my car because I’d use them every day as I do in the semi. How would those buttons be worked into this system?

[@umnscx13]

If we have 2 headlights on each side instead of one, do we need anything extra to support the circuit, i.e. more relay or more fuse?

[@WiringRescue]

Yes! So it all depends. Are you going to have two low beam headlights and two high beams? If so, that’s a slightly different circuit. If you did four lights that all swapped from low to high, that may be weird on a car. A normal headlight is between 35 and 55 watts depending on which you choose. That means it can draw between 4-5 amps of electricity through the circuit. So if you had four of them, all on at the same time, you would draw 16-20 amps. That means your fuse should be somewhere around 20 amps and your wires all need to be thick enough to hands 20 amps. Most relays can handle 30, so you are probably safe there, though it’s worth double checking.

I have a suzuki forsa 1988 and my headlight switch is damage is very hard to find and super expensive so i have a question my light switch has 4 wires one is for the headlight dimmer one is for ground the other one is for the park light and the other is for power can i wire this to a relay with one switch or i have to buy an universal switch any help will be appreciated

[@WiringRescue]

Unfortunately I don’t think I can be much help because I don’t have any experience wiring those. The biggest thing to note is that you need switches that are rated at an amperage that can handle the circuit that they are powering. If you use switches that are not rated properly, it could burn the switches or even catch on fire.

Can I use a 2 prong on off switch with this setup and just put the white wire and power wire together on the on side of the switch?

So are these bulbs why cars went from 4 head lights (4 high 2 low) to just 2 headlights that can do high and low

[@WiringRescue]

Pretty much. Car manufacturers were required to use certain types of lights by the department of transportation for a very long time, decades. That’s why the cooler car manufacturers had pop up headlights and hideaway lights. They were trying to make their cars look good when they were all forced to use the same lights. Imagine if that were still the case? Ford, Chevy and Toyota cars and trucks all shared a single headlight! It would be totally bananas, but that’s they way things were from the 1940’s until the 1980’s. These dual filament lights were a small way that car manufacturers could gain some flexibility in the car design rather than the dual lights on each side. Fun stuff right?

Thanks for this super helpful , I'm working on a 64 chev impala and the dip switch is faulty . Would a normal 3 way toggle switch work?

[@WiringRescue]

I also have a 64 impala. A normal 3-way switch would probably work I would think, but the new floor switches are very cheap. I think the one I recently bought was like $15. Maybe just get a new one?

@@WiringRescue cool, many thanks man.

I’m wanting to put lights on n old Ford 2N Tractor. I want to have tail lights with optional flashers/warning lights. There is one wire coining out of the fixture. What’s the best way to have them powered with two options? (Solid on, flashing and, of course, off. Thank you.

How to wiring headlight using ac voltage and other one using dc voltage using same switch?

Does the low beam go off when the high beam goes on

[@RobertJohnson-yi2mu]

First I want to say, great video. Very well laid out diagram and clear. But why wouldn't you wire it so that pin 87a is low beams and the high beam contact on the dimmer switch triggers the relay. That way you only have control voltage going through the dimmer switch.

[@WiringRescue]

There are tons of different ways to wire a circuit. My video was just one option which may or may not be right for your application. If it were wired as you suggest (assuming I understand it right), the low beam headlights would be on all the time, possibly even with the car off. That may be the preferred wiring for some scenarios, just not the one I was trying to demonstrate. Maybe I’ll do some additional headlight wiring videos showing additional methods.

[@RobertJohnson-yi2mu]

@@WiringRescue you're right. I didn't even think about that. I was trying to keep only control power going through switches so I guess my way would require two relays. One triggered by your on/off switch to give power to the headlight relay, and one triggered by the dimmer switch to control hi/low. Little more complexity but keeps lower amperage running through your switches which I like. But either way man, still a great video. I wasn't trying to hard talk you at all.

[@WiringRescue]

@@RobertJohnson-yi2mu - I also like to use relays to keep switches alive longer. In the case of these floor-mounted headlight dimmer switches - generally they are only powering two headlights at once, which should be less than 10 amps. I found a spec sheet for one of these floor-mounted dimmer switches that says it is rated for 20amps. So wiring the way I did in the video should work very safely without any additional relays, assuming the wire gauge and fuse is also correctly sized for the application.

If my headlights use a 12 gauge wire to feed power do I need a relay with 12 gauge wire
