Ever since my firstcar, i have been buying lights from one person and only had problems with the bulbs once and he very quickly send me a replacement. If you want I can give you his e-mail Ir ecently purchased 4 SETS (8 bulbs) of h1 superwhite bulbs for about $35.... So let me know, heck tomorrow I'll look at what color the cables were that I cut from my parking light to power my DDE's (the good parking light delete) and let you know.
