"Golf" 3rd brake light?

A while ago while driving I spotted a Golf with a 3rd brake light that when lit up said "Golf". From a distance it would look light a regular brake light, however upon getting closer you could see it. It didn't appear to be an overlay sticker. Any ideas where I could find this? I've tried searching around but couldn't find anything.

Haha that's interesting, never seen that before. Hoping to see if anyone else has

Ehh not quite, it wasn't an overlay, the actual LEDs appeared to represent the word "Golf"
