What can cause a low beam headlight to be dim?
If it is, use a voltmeter to see how much power, if any, is reaching the headlights. If there is no power reaching them, there is a break in the wiring somewhere between the fuse panel and the headlights themselves. Thanks! What can cause the light to be dim except when on the high beam setting?
What are the wires in a headlamp relay?
In the diagram, the top wires are voltage, bottom wires are ground. The dimmer switch is part of the ground circuit, if you wan t to word it that way. The low beams ground through the headlamp relay in diagram. The high beams ground through dimmer switch ground. The ground wire location is the same for high and low.
What is each wire color for each headlight wire harness?
Right front turn signal wire is dark blue. Right rear turn signal wire is dark green. Grounds are black. Common power for tail and license plate lights is black and white. Common power for front parking lights is yellow. High beams are pink wires.

What to do when your low beam headlight blows out?
You can often tell when a headlight blows out while you’re driving, but confirm which bulb has actually blown out by leaving your headlights on and getting out of the vehicle to check. Then get back in your vehicle and turn on your high beams. Some vehicles use a single bulb for both high and low beams while others do not.
