just to start i just joined this is my 1st post so please be nice lol. i've looked around threads prior to writing so if there is a post already please tell me where to go if not here we go. i have an 04 6s wagon with sport package. i want to put hids in the low beams, ive been looking at the phillips kits are they worth the money 1st. and are there any detailed instructions, videos etc on this before i but and try it. i am mechanically inclined i just want to know what im getting into before i do it. also that black cap that seal where the bulbs goes, does that stay on or does it stay open, how does the ballast connect to the bulb otherwise? anything to help me in the right direction would be great thanks again.
