Flickering headlights on a 2005 Silverado may be caused by faulty relays or electrical wiring. The fuses and lights may also be going out.

how to adjust headlights on 1992 silverado
Probably your alternator.
The alternator is on the way out.
The headlights on a 96 Chevy Silverado are adjusted by turning the screws on the top and side of the headlights. It allows the lights to be adjusted for optimal night vision.
I have an 2005 and the headlights on it will dim, and then brighten back to normal. I bought it brand new, and it has done it since I bought it. I actually took it back to the dealership, and asked them about it, and they said that Chevy knew that it would do that, but that the car would keep running, and that there was nothing that they could do about it. Hope this helps.

You may have a pull on your batt, or a surge.
