Question......would Misterjungs HID kits work in old two peice halogens?

audidood

but usually everyone that upgrades to HIDs also upgrades their housing as well. would the beam pattern change?

Yeah you just have to make sure that you get the bulbs for non projector housings

My buddy put them in his 91 maxima, his beam pattern did not change... his bulbs are direct replacement and have the same exact filiment / arc location as the original bulbs

I thought the arc in the xenon lamps was bigger than the tungsten coil in a halogen lamp? That would mean that the xenon lamp will not be in the optimal focal point of the reflector.

make sure the kit has bulb that is converted from D2R bulb.

If you have the projector-type headlight (newer audi headlight) then you have to use the bulb that is converted from D2S.

D2S is a clear bulb without any light restictor. D2R has restrictor around them (black stuff).

D2S is used for projector light, and D2R is used for regular headlight.

It's come up before, but nobody ever seems to really know about this.

I have the old reflector ecodes, and those don't have a sleeves around the bulbs like the crappy old DOT reflector lamps. Would a D2R xenon bulb change the beam pattern or not?

That's pretty interesting. Do you have any url's? I would like to see those.

2-piece 3-in-1 (low/high/fog) Bosch reflector ecodes:

I remembered incorrectly. They do have those bulb sleeves...

-glass lens/diffuser
-excellent beam pattern

I bought them on a trip in Germany. I can take pictures and post them.

the difference would be in the intensity of the immediate lighting area. The pattern would "bulge" slightly in each irection but nothing worth recording..
