ok i have a 85 cutlass. i got some bulbs out of a gas store to put in for my License Plate Lights. they went in like it was nothing to it,so i cut the headlight switch on and they work,,, but before i could have put them back in the housing the bulbs was already hot as hell. so i waited and next thing i knew the bulbs were burning up, they start to turn black... any idea's what is wrong with my light please i need info ASAP...thanks guys
