as of last week my gauge cluster lights have been dimming and slowly coming back up to its full brightness. So i thought i needed a new battery and got a diehard put in last week. Well the same thing hapend again tonight, only tonight it was worse and the battery light and parking break light were on the whole drive home. And i havent done any electrical mods lately to the car.

Anyone know what could be the problem??
