First, check that the battery connections are clean and not corroded. If not look for the ground wires that connect to the chassis. Check to see if any are corroded or loose. Finally if that has no effect, you have a short somewhere in your wiring. The easy way to isolate it is to pull the fuses for each device one by one and see if the dimming stops. The last one to cause the dimming is the problem. If it happens when you hit a bump it also might be a ground fault in the interior car grounds....good luck!

there should be 2 brackets at the rear of bulb housing, 1 may have a small bolt.....lift these up and the headlamp housing should come out. you will see how it works when you get it apart.

2009 lacrosse...compass, clock and milage lights sometimes stay real dim and then later pop up to normal brightness so I can read them...what goes ?


Starting car in garage turns on headlights which makes believe it is dark out and therefore dims dash lights. When car is out of garage it switches to running lights which allow dash lights to get brighter. I guess I should have figured that !!!
