Hey what did you do to seal up the back? A friend of mine did some ghetto way of having to use duck tape and told me that he worked on it with see_fu and said there is no way but to use duck tape to completely seal it up. I thought it looked really ghetto. I want to try to avoid this if at all possible. I bought myself a pair of audi a6 projector, ballasts, and bulbs all for $356 shipped to my house. Just waiting on that and trying to find a used set of oem headlights.
