Silverado Duramax Headlight trouble

Unread post by baron » Sat Feb 27, 2010 11:40 pm

I was wondering if anyone could help,
when i accelerate quickly and get my rpms above 2500 the headlamps dim, and then when the rpms get back to 2000 and lower then are bright again, what could be causing this ?
thanks

Bobby

Slipping belt, or faulty alternator.
