this could be helpful to some but I was parting out my most recent parts car and discovered that the guage lights (light bulbs on the back of the guiage cluster) are the exact same light bulbs used for the running lights on the front fenders and rear quarter panels. this may not be any new news but I thought I had to wroter this especally anyone goes cruising. in Mn if you go to University ave and any of your lights are burned out or flickering you will get a ticket and if you have a parts cat or even just an old guage cluster laying around then it is a good idea to keep a couple of those bulbs in your car in case you need to change on out quick. this is at least true with 82-84 Firebird/Trans Am's.
