SOURCE: REPLACEMENT OF [LOW BEAM] HALOGEN BULB IN 2004 Buick LeSabre

I just Replaced a Low Beam Light bulb on a 2005 Buick La Sabre.

If You use a Metric socket and Remove the Two Silver bolts Attaching the headlight Assemble onto the metal surrounding the the lamp assembly it comes out to the front. This makes it much easier to access the bulb. Twist it counerclockwise & it comes out by pulling gently on the bulb. Then by realeasing a tab that is the socket holder bulb can be removed & replaced with a New #9006 low beam halogen light bulb. Wrap a Paper towel around the bulb & do NOT touch it with your bare hand as this wiil ruin a halogen bulb,

The bright light fitting is the same as the dim so take it apart fist to see how the cover screws off/on and the light comes out. Both the cover and the bulb are removed by a standard twist to the counterclockwise and replaced by a twist to the clockwise. Now to the dim light. You have to release the entire light assembly before you can remove the screw-on cover to reach the light. On the rear edge of the light unit closest to the engine is a white locking tab. Pull that tab up just to the point where it releases…pull too far and it locks again. Next, locate the other locking bracket which is a metal bracket in the center-rear of the light assembly. This bracket is held down by a screw. Remove the screw with a 10mm wrench. Lift the bracket just like you did the white bracket. You should now be able to pull (or pry) the entire light unit forward a little. Depending on the size of your hands this might be enough. If not, then you need to release the plastic bumper assembly to give you a little more space. This is done by removing two expansion locking pins, one that holds the little plastic strip down between the bright and dim lights and one that is located inside a rubber bumper on the engine side of the light unit. To remove these locking pins, pull or pry up the little tab in the center of the pin just like you were pulling a nail by the head. That should give you a little more space.

The relay under the hood may have gone out. We had the same problem on our 2007 Buick LaCrosse CX. The bulbs were fine, high beams worked, all turn signals and everything except the low beams turned on. Turns out the relay had gone bad.

Possible relay fault,also a burnt dimmer switch will cause this symptom
