    Question Dimming head lights?

    I have a 09 Silverado with 11,000 miles and the headlights seem to dim too easily. If I'm driving along at night with the windows up and try to roll up the windows (when checking to make sure they are closed) and the headlights dim at a very noticeable level.

    Has anyone experienced this?

    Tapping the power door lock buttons to the beat of the radio makes for a nice light show too.

    Both of my Silverado's did that too, I think it's a quirk just like a Harley leaking oil they all do that LOL!

    Ive never noticed this happen on any vehicle I have driven, except the re-worked electronic system on the 2007+ GM vehicles - trucks, an 07 impala i drove once, and my moms 08 buick lucerne. I also saw a cobalt the other day that couldn't handle its stereo at a stop. The guy had a sub in it and everytime it hit, his brake light lost AT LEAST half of their brightness (although this was hardly the fault of the car - you just shouldnt put that into a car with and alternator that cant handle it at idle).

    Are your lights dimming when you are "driving" or waiting at a light at idle with the foot on the break. If you are driving there is no way that should ne happening, I would suspect a weak alternator, or loose connections.
