How to wire a low beam and high beam switch?

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?

Why are the dim lights on my Chev not working?

The dim lights on my 2004 chev. Impala will not turn on. The daytime driving lights work, however as soon as the sun goes down they turn off, as they should, and the dim lights will not turn on automatically or with the switch. The brignt lights work fine.

What to do when your low beam light goes out?

Disconnect the battery. Be sure you remember which side of the car has a blown out low beam bulb before disconnecting the battery. To disconnect it, use a hand or socket wrench of the appropriate size to loosen the nut holding the ground cable onto the negative terminal of the battery.
