Thanks - I think it will be tough to fit the ones I currently have. I'll call TRS and see what they think; may end up going with the Matchbox Mini's. It sucks, because the ones I currently have are Bi-Xenon, which would be lovely for a fog setup IMO. Moar bright lol

 

every time I read the bulb threads I think I should have payed more attention in physics with the electrical stuff. Never interested me and I never had much to apply it to so it was in one ear and out the other
