Out driving last night and I noticed the dash lights pulse, I checked the volt gauge seemed normal , It was intermitant ... of course they always get brighter the faster you go !!! loose wire? :help:

Check the rheostat. They get dirty and don't always work well.

check your load draw to the lights the fusable link and the switch itself sounds likea amperage problem that is causing the lights to dim. if everthing is fine calculate total electrical usage amd make sure you are running the correct alternator for your needs and regulator.
