so it looks like my ballast is bad, swapped them today and found that the left ballast works on eithter headlight. the bulbs themselves say 6000k on them, so i am going to assume that is right. the wording on the ballast is as follows:
5DV 007 760-01
DOT D2S,D2R 2500h
made in germany
What is a good ballast to replace this with? or should i replace both of them? i dont know where these originally came from, and i dont know what would be comparable. would replacing the bulbs with 4300K make the ballasts last longer?
