As an option, just use a couple of pieces of Gorilla tape to patch the hole. If you need to replace a bulb, replace the Gorilla tape after install. I'm putting Gorilla tape over the access door anyway, so I don't lose another one.
Thank you. I will definitely be going the route of the Gorilla Tape. I switched out my HID kit and had not yet solved the open bay problem. It appears I blew a fog HID kit yet again.
Concern: I wonder why a little water would fry the bulb or circuitry. Probably a question for DDM Tuning (the manufacturer of the kits). I wired everything perfectly and did a rather clean job with reinforced electrical tape.
Slightly disappointing to have to buy multiple kits and do multiple replacements. Quite a hassle as you all probably know when you keep the wheels on the car.
