I have a question for you since you work for Umnitza. I have an '02 M5 and recently purchased this headlight from your web site (Description : 1-Projector39 with Predator Angel Eyes** & DS2 package). I wanted to make sure that it was going to be plug & play with my vehicle or will I need more parts. (i.e. can I use my existing ballasts?) Thanks in advance!
