wus up guys. i have some problems with my indiglo gauges going dim after a few minutes.

well heres what i found out. the gauges work fine when the car is off with no problem. then when i turn on my car after 2-3 mins the gauges start to flicker and turn dim. why does it do that?

and while its all dim, i turn off my car and the gauges start to work nice and bright. i have no idea what the hell is going on . any one got a solution? thanx an advance
