I am looking for information I once saw on a custom car/truck show or maybe it was a magazine. Anyway, they had a LED third brake light assembly that they mounted flush with the body but actually put a coat or two of paint over it so that when the light was off, you saw absolutely nothing, but with it on it would shine through the paint. I have searched on here as well as google for hours and while I feel I am inputing the most probable search terms, I am still coming back with nothing.

Any help would be appreciated, thanks

Pete
