Question type: Maintenance & Repair

I drive my 2003 chevy impala for about a half hour and my dome lights (
lights on the mirror and back seat lights) come on and slowly fade out. A

frequently they come on in other words the light will just fade out and come
right back on but when it first starts there is more time in between before it
comes back on please help I just got this car 2 months ago and have been
buying parts left and right and am paying on a loan for it so i cant really
afford much money.
