I have been looking at HID kits on the ebay and read in one of the auctions that the ballast should be in a ventilated area because it produces heat. I would hate for yours not to last as long as others because of trapped heat. Just an FYI and I do not know for sure if it will hurt it. I did have a kit on my mustang and ballast do get warm.deezyellownutz said:The insulation I used is kinda like foam, used in the seats. I just wrapped it around the ballast and then taped it so its like surrounding it. So then I just stuck it in between the inner and outer fairing in that little space. The foam forms around the space and holds it in place. No glue, zip ties or nothing, just the fact that it fits in there.
