Yeah hot glue seems like a good way. For the camaro I'd go buy a couple cheapy little flashlights and steal the light buckets out of them and drill for the proper size of the LED!

The camaro lights are round so I think it would work great. I love that camaro body! If you look at my gallery you can see two different black ones I did. I know it's not creative or anything, but I like the camaro solid black.
