I have this problem that whenever my headlights are on, when I use the turn signals my headlights and dashboard dim on and off. At first I thought it might be that there isn't enough power... but it's a brand new battery and a brand new alternator. Plus if it that was the problem, then the lights would dim in accordance with whem the turn signal bilnks, and it doesn't always do it in a pattern.

Does anyone have a thought or suggestion for this?
