I thought these kits were out for a long time now. They run like $400-500 easy for the kit. It would definitely look nice on the car, but I drive a lot at night through areas where there is a lot of deer and small animals so I would prefer the output from the OEM fogs. I considered the HIDs greatly though.
Yeah what are these. Would they allow us to have bi-xenon upper bulbs? If so I would think they need a second pair of ballasts like the dual-xenon H4's on ebay.

What is the hype with the "new" D3S/D3R and D4S/D4R HID bulbs? These new type of bulbs will look identical to current D1S/D1R and D2S/D2R HID bulbs except they will be Mercury free, to meet the environmental priorities of both manufacturers and consumers while conforming to all international specifications. D4 type and the equivalent Mercury containing D2 type will need compatible ballasts to operate

D3x and D4x are mercury free versions of the D1x and D2x light sources. They do not work with older D1x/D2x type ballasts because steady on voltage is only 36 V. Compare that to a D1x/D2x style, and u will see that voltage is 85 V. In detail, 42 +/- 9 V can be measured at a D3x/D4x bulb. They have same output, same life as D1x/D2x bulbs
These are interesting... just don't seem worth the money for nowOriginally Posted by Automotive Lighting FAQ

the whole thing is i've seen places saying that they will work with d2 ballasts and some that wont.
also some forums that have members saying they threw them in and it worked while others saying, although not tested, that they wouldnt work...
im gonna test out the waters
