hey man, gotta question about your lights. my roommate has an 07 600 and had issues with a different brand of HIDs. and when i go on leave(depoloyed) ill be installing some on my 07 750. but not the brand he bought now. do you have your highs and lows done? and did you have to use a relay harness or time delay relay? any help would be great. thanks and hope to hear from you soon.
