Alright, so I've decided to go HID with my JDM foglights for my 99 TL, problem is the bulb is japanese, and I can't figure out what the exact size is because all my searches come back with japanese pages. I have fit a DR2 bulb in there, but it is pretty tight and I think that may be a problem if i hit a bump and it moved a little, right?
The bulb looks similar to an H1, so I may go with that just for safety.

Can anyone shed some light onto this for me??
