Sounds like a ground somewhere. I am having the "dim lights" issue on my 97 K3500 Crew. I cleaned all the grounds and it got better for a while. Now it is not as bad as it was but lights are dimming again. I now plan on replacing the battery cables w/ bigger ones and may go w/ top post terminals as well. Also I will replace chassis grounds and such while I am in there.
My problem doesn't sound as bad as yours, but grounds would be a good place to start.

I agree with every thing Hraney said but just for grins and giggles check the stacked positive terminal on the right side battery. But remember my golden rule! If things make sense you can check the positive side.But if it acts wacky makes no sense checks the GROUNDS!! Grounds will get you every time!!!
