hmmmm I'm hesitant to take those dam HID's out because of how hard it was to put in. put me through hell. Is that cap really expected to make a seal? I figured it was just for dust not for condensation issues, but thought I would mention it anyway just in case. I would think it would be an issue with the headlights themsevles due to all the previous problems and the TSB that is out on them. Just wanna make sure before I take them out, it really was a ***** putting them in, almost gave up lol.
