what is this indicator light. it's yellow and i think it's shoing light coming off the rear. it dosnt always come on. i notice it does when i step on the brake tho. ichecked out the lights and they are all fine... what gives?

 

if it comes on after you step on your breaks and stay's on until you turn off your car, its one of your break light is burnt out. They are Dual filament bulbs. so even if they seam to light up. the 2nd filament which lights up ONLY when you apply the breaks and have your headlights on might be burnt out. have someone step on the breaks for you and compare the 2 sides.

 

Jmai is right. I had the same light last week and found it was the inner driver side taillight (had my bro step on the brake).
