It may be from some corrosion or rust, brittle wiring or loose connection.

That's why so many people have trouble with dim headlights. The new lights drew so much more power that the existing circuit breaker in the headlight switch was being overloaded. If you have no idea why you might even want to do that, let alone how to do it, read on. Here's a good place: Third, make sure you use the right gauge wire. Q: number of interconnection ways.
I think that you would be better served to have them on their own switch. Note that in the original version of this diagram, I had the labels for the right side headlights reversed - it has since been corrected thanks to a sharp-eyed reader who pointed out the mistake to me. I: number of the function involved. Tip: You can buy trailer wire cable to run wiring to the back of a car. There are 3 fuses to check.
If you know what that means, now you know. That resistance sucks up electrical energy that could be used to produce light at the headlights, so your lights are dimmer than they could be. . Make sure it does not interfere with anything like closing the hood or getting to anything else you may need to service on the engine in the future. There was lots of good info in there, but the hand-drawn wiring diagram was less than readable - even for someone like me who actually understands how this all works. Ford truck information and then some Ford Truck Enthusiasts from 2008 f250 headlight wiring diagram img source : ford-trucks.
That's why you need relays nowadays. I would be driving along, and all of a sudden, all the lights would just go out. Wiring up your lights doesn't have to be too complicated. See the lighting diagram below. It should be zip tied in place to keep it that way. Use the existing high and low beam wires coming from the firewall to trigger the relay, run a new high power feed with a fuse! Instead of the power having to go through all kinds of connections, switches, tons of wire, etc.
Too small a wire can cause resistance, low voltage, and dim lights. There will typically be two wires - one for the low beams and one for the high beams. Check for good ground and then for power when switch is pulled. For reasons I am unable to fathom, some people produce and sell relay kits that have no way to mount the relay. The second reason is to simply improve the brightness of your existing headlights.
So, use the right size wire. It's cheap, by the foot, and protects the wiring from any cuts, wear, etc. However, many cars suffered from dim lights from the factory. Once you confirm the fuses are good, test for power and ground at the headlights. To find circuit and wiring diagram now a day its easy. If in doubt consult a factory wiring diagram for your car or break out the old multi-meter and do some testing and tracing of the wires in your harness to figure out what goes where.
So read on and learn how to do this. I prefer to connect them both together. Finally, I figured out that what was happening was the light switch itself had corrosion inside it where you couldn't see it. If one was out and now both, start with replacing the headlights. The first is that you have installed high output headlights off-road units, etc. E-learning through internet as a right place to search an exact circuit and wiring diagram of your choice and it's much fun and knowledgable. Once that checks good move to the headlights.
J: representation of a wire depending on vehicle specification. Just make sure the gauge is ok for what you want. S: representation of a partial interconnection. Good power and ground means replace the headlamps. Really needing to get this ccfl wiring figured out. Whatever you do, just be sure to get relays that have a connector and wires with them along with a way to mount them. Second, make sure you are able to tie into good power.
H: representation of information going to another function. However, it worked just fine when it was cold. Basically, what you are doing with relays is supplying a short cut for the power. See my for more details. When I would try to figure out what was wrong, I had the door open, the switch cooled back down, and worked fine. Then add in the years of corrosion at connections, wear at the light and dimmer switches and the amount of resistance in the circuit goes way up. You can either tape off one of the low beam wires or connect them both together where you make the relay coil trigger connection.
If you are using split loom to cover the wiring, still be careful of these considerations. You should read the entire list and understand it before you start this project.
