I used vinyl to do it...but it only cost me $5 because of a friend who owns a body shop. I removed the housings. I had some issues with laying it because it wanted to bunch up on the edges. I just took it out for a drive and the lights are very dull. Almost a blue color now, but my friend Matt told me a few minutes ago (after driving it) that the vinyl is the equivalent of 20% window tint...no wonder I can barely see! I'm gonna strip them in the morning and just put LED bulbs in later in the afternoon. I would rather have functional than cool.
