Change the bulb. Some cars have one bulb others have 2. Without knowing your model there is no way of knowing. If you problem persists you may need to replace a fuse relay or the socket and wires. But bulb is more than likely your problem.

SOURCE: low beam headlights do not work, but high beam headlights do

Clyde,

I've been troubleshooting this same problem on a different vehicle this week, and I can give you the steps I'd take.

1. If both sides went out at the same time, the problem is *NOT* likely to be the bulbs.

2. Check the fuses to see if both low beam lights are on the same fuse. Many cars have one fuse for low beam and another for high beam, so both lights out at the same time typically means fuse blown.

3. If the headlights are OK and the fuses are OK, then the problem is *LIKELY* the headlight switch. In my case, AutoZone has one and it can be installed easily; but in your case, that may not be as simple.

Please post your findings or comments.

SOURCE: high beams wont turn on.

First place to start is with headlight switch. I did have a case many years ago when both high beams were blown out at once, but this is rare. When you have the headlight switch out, jump power from te low beams to the high beam contacts. If high beams come on, replace switch.

SOURCE: Jeep Headlights not working. High beam works

had the same problem on my 92....check under the hood on the drivers side,towards the front,there is a "junction box" with all of the lighting wires connecting from the switches to the lights.My wires were all corroded inside,so I cleaned the ends and bought a new box from the local electronic supply store.The problem has not come back.

Could be the relay for the lowbeams is faulty, if your DRL's are your lowbeams, then your DRL Unit could be bad. Also did you blow a fuse cuz a random surge could blow the fuse

SOURCE: 2006 grand prix low beam headlight do not work,

I'm having the same issue. I have changed the bulbs and fuses. I can't find a relay but I don't think that is the issue. Some other people have suggest the Dimmer Control Switch. I am working on that. Please let me know what you find out.

Headlight low beam r side no power high beam works fine

Sounds like the low beam element in the right side is burned out. The auto parts store should be able to verify that and sell you a new bulb.

One low beam head lights will not work, high beam works though

check for a damaged wire for the low beam. Also wouldn't hurt to check the ground wire as the high beam will try and ground through the low beam but not visa verse

2002 pontiac grand prix gt. High beams are dimmer

A loose ground wire to the headlight will keep it dim,Or a headlight adjustment will bring the headlight up.If you can have your headlight turned on a garage door or something at night,and then watch as you change your headlights from low beam to high beam which ones are higher.the last thing to verify is that your high beam headlights are not the plastic lens type that turn dull which cuts the light power.
