We have a couple of options for 1st gen Camaro/Firebird interior lighting, everything from a led bulb for your dome light to a completely new assembly. In addition, we have a footwell lighting kit and center console lighting options. All led products on the link below use Diode Dynamics bulbs which have a 3 year warranty and brighter than most other led bulbs on the market.
