Hi. New here and my first post, so I thought I would try to be helpful. I recently bought my 3rd Trans Am, a standard issue 1977 with black paint, gold decals and firethorn red interior. It is a base model that has a few options, am/fm stereo (according to the build sheet, anyway-there's a non-working plain old am radio installed currently), power windows, power door locks, air conditioning, auto trans. That's about it. She has 74,xxx original miles on her. I will be doing several mods to her over the next few years, but the first thing I wanted to do, was to upgrade all of the lighting to LED, starting with the somewhat dim 1157's in the tail light assemblies. I have used these bulbs in other applications:

They are now in my T/A, and let me tell you, they are FAR brighter and more visible than the 1157's they replaced. And a set of 6 is only $62. If they hold up over the long term, I will be more than happy with the money spent.
Just thought I would offer a less expensive option for those that are on a budget.
