I've been doing some reading, and I really want to do a retrofit into my car. I like the idea of the Hella H9 to D2S since it seems fairly budgetable and performs well.. But here's my question.
I'd like to have Hi/Low beams out the same projector, I know I could buy Bi-Xenons that would give this to me, but Would it be possible to fit a dual-beam H4 kit into the Hella 90mm and it function as Hi/Low??

I know the optics might not be right for the H4's beam pattern, but I just wanted to get an opnion from ppl that are knowledgable rather than me guessing and wasting $$

Thanks

me thinks its not quite advisable to do so. the h9 projectors have a shield that blocks out half of the reflector within, you wouldn't get any high-beam dispersion pattern out of it even with a movable hid capsule. better off either going bixenon, or try to shoe horn in a 2nd set of projectors/hi-beam unit from Hella.

With a H4 HID kit, you might be able to get low beam function, but high beam will be garbage. Also, any kit will degrade faster than a original D2S bulb.

get the bi-zenon 90mm's.
it'll save you a LOT of trouble as it is easier to deal with a complete and well engineered product than messing with other stuff.

Ok thats what I was thinking.. Its just w/ the cheap prices I've seen for the H9 Hella 90mm and I was hoping that it could work out with the H4's.


Guess I'll start researching some bi-xenons

Whats the price range I should expect for projectors/bulbs/ballasts for bi-xenon? just so I dont get ripped off thinking i have good prices.

Or any recommendations as to where to locate them??

Thanks for all the help
