its been a while since i installed these hid's in my old projectors. now im putting them in stock bulbs. the pin on the hid that runs length wise of the bulb is supposed to be faced up correct? thanks in advance. searches have been done and found nothind with this specific question

 

the tabs on the bulb itself determines how the bulb fits in the actual light housing..
Basically it should only fit in the housing one way

 

i dont have an aftermarket kit. and im putting this in my stock head lights so. can you be specific as to which way it goes. the tab your talking about is the little sleeve that sits on the bulb

 

 

I'm not quite sure, but after reading a few HID threads, dont HID bulbs + stock housings = hella m@d headlight glare = blinding everyone passing you? Or am I thinking of HIDs in shitty projector lamps?

 

mine faces down...

but regardless if its an aftermarket kit or not that bulb should only fit in your housing one way so that it is seated and will not move when you hit bumps and potholes!!!!


if aimed appropriately you will not glare oncoming traffic, don't get me wrong its not as crisp as projectors, but it 100% more effective than halogens or even the ever so popular silverstars

 

of course they should fit only one way. thats not my question. im doing the conversion with the h4 plates so they just sit there.. but im asking is which way they face. can anyone say for sure its supposed to go a certain way or it dont matter

 

what housing do you have your hid's in?

 

the bulbs should face up i believe

 

i just went outside (in the snow) and checked mine, the pin on mine is definitely on the bottom/faces down

 

and how do they light up?

 

not sure i understand your question..
i'll try to answer anyway.. mine only fit in my housing in one direction so there can be no confusion in which way the pin faces (down in my case). if i were to guess they reflect the light from the top of the housing down, to reduce glare.

 

the picture in my sig was b4 i adjusted the beam, so you can see that the right side has glare and the left side does not.
