I figured I would post this here as well, that way anyone else who may have done this can help. Its not important that you have an 850 I suppose, I just would like to know anyones experience with converting there headlights with a HID kit. Im refering to real Hids of course, I have played around with the bulbs for years now, I like em and all, but I want real ouput, none of this kitty cat footen crap I have been doing, hehe. I was thinking of going with the E-code lenses and then getting a conversion kit. Is there anything to look for in the kit, any recomendable brands, any ones to stay away from? I was told by a local performance shop that some of the early conversion kits required intense modifications of the housing along with using cheap unreliable ballasts that would burn up. He told me that new ones dont have this problem, even the cheaper affordable ones. I have been looking at the ones available from Autotoys, they seem to have the most complete line of Hids I have seen, they have both a 6000k and 8000K set. The 6000K set is available in blue or purple look, and costs a bit under 400 dollars. Then for a bit over 400 dollars I can get the 8000K kit with Hella ballasts. One thing I dont get is this Color Temperature stuff, how can something have either a blue or purple look but both have the same 6000K rating. I thought the rating was infact the color, I thought thats what Color temperature meant. I also dont understand this 8000K stuff, shouldnt that be nearing the UltraViolot range, I guess not that bad, but isnt that beyond the point of White light. I guess I dont really understand colortemperature in relationship to the color spectrum. Thanks.
