You don't want HIDs in standard Stilo headlamp units, they chuck the light everywhere, have seen it first hand myself. You want to install proper projector units ideally or just use uprated xenon bulbs.
id assumed he wasnt talking about those cheapo ebay kits....if you are then STAY AWAY they are crap....uprated xenon bulbs? are those the halogen ones with mythical xenon gases inside? (i'm dubious as to there effectiveness, when i tried them they were nowhere near as good as nightbreakers, on par with £1 H7's from the garage)....as MEP said, and in my opinion, for real xenon light output, projectors are the only way...reflectors are just too imprecise
Id love to do what youve done Hussein....but i'd balls it up lol
i want to say "its not that hard" but it took a **** load of effort, including me giving up half way through because progress was SO slow....but it is worth it in the end, i reckon i could do it again in a day, the first light took about a month to do an figure out, the second one took about 2 days...
