This Low Beam Conversion kit was used once for about 2 weeks. It was installed in a Range Rover and the conversion kit was not compatable with the Range Rovers onboard computer system. They were given to me to put in my 2005 F-150, but after I looked up the specs, this was not the proper kit for my truck. Everything is included: all wiring, set up manual, ballasts, diodes and bulbs (H4-7000K) . I know they were originally purchased for about $550.00 They are stillin the original box. The only name brand markings on them are on the ballasts that read "Vega" The box has a bunch of Asian writing on it and I am unable to translate.This lighting system is compatable with: C-Class 94-96, E-Class 94-95, S-Class 2dr 94-96, S-Class 4dr 94-UP, 300(SD,SE)/500SEL/600SEL 92-93, 400-SEL/500SEC/600SEC 93-UP, and 400SE 92-UP. If you are interested in these lights, I have posted them on ebay. The link is: http://cgi.ebay.com/ebaymotors/ws/eB...;rd=1&rd=1. Thank you for your interest.
