I don't know if this was asked before but sucks not to have the serch. I got a pair of Sylvania Ballast from a Mark VIII and i was wondering what kind of 9004 bulbs would be compatible w/this and where to get them. Thanx in advance.

well you need the 9004 capsules. These are already made to fit your headlight just like a simple stock bulb. You can try and buy some from www.misterjung.com since he sells replacement capsules for like 70-90 bucks. U might wanna email him and give him the ballast model number to make sure that your ballast are compatible wih his capsules.
