I searched the forums to see if there was a thread on this and I didn't find anything. Does anyone else with a 2007+ Silverado ever notice their headlights dimming? Mine dim slightly (but noticably) every once in a while. This has been happening since I bought the truck but since it is not really significant, I haven't had the dealership investigate anything. If anyone else sees this happening in their truck, I would like to hear about it and if there is a fix for it. Thanks in advance!
