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?

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!2004 Chevy Colorado

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.99 K1500 Suburban LT "THE BEAST"

i can see it dimming a bit when you are at idle, but if you have no accesories drawing extra power then it should never happen especially while the vehicle is moving. i have 2 subs and 1000 watts between two amps and NO capacitor and it never even dims when bass hits at idle. Something is drqwing power, loose connection or corrosion sucking power from alternator or battery
