I have seen a few members who took the front clear side markers and were able to use them in the rear by flipping them and doing a little DIY instillation work.

I really would like to have them all around the car as I have them only on the front as well. I good deal has not presented itself however for me to acquire two more. Needswings use to sell them, when I asked Rob about them he said, "I do not know if I will ever be able to get them in again." (BUMMER!)

I do have some front yellow ones sitting on my parts shelf. If you would like I could send those to you, they at least have the housing for the bulb.
