How To Shim A HID Bulb For Proper Alignment

[Mostafa United]

any shimming ideas ?

[Pklemm]

Shim upward. Place a piece of a cereal box at 6 o'clock spot of the bulb.

Permed the clear lens mod on my G37 projectors, but feel as though the hotspots are off?

It's hard to tell in that photo because the projectors are facing right into the ground. Is that how they are aimed?

No, my driveway is sloped so they're facing the ground there.

Heres another picture, hopefully this one is better:

The placement of the material depends on the direction the hotspot needs to go. So if it needs to go up, the shim is placed at 12 o'clock. if the hotspot needs to go down, you place the shim at 6 o'clock. And so on

i think HK45 is right

i did shimming on 12 o'clock but other areas got worst.

i think the problem is the bulb itself as it is not High Quality ( Cn-Light) because other side is very OK

What you're going to need to do is undo the bulb for the bulb holder and move the bulb up and down just slightly to see where the best spot is for the hotspot. If you could get a shot of each side with the other side covered that would be best. I want to see what's going on with each side. Maybe stand in front of each side and snap a shot?

probably noob question... will incorrect rotation affect hotspot? if so will get the rotation fixed first then do the shimming... thanks!!

No, the rotation of the projector won't affect the hotspot. Do the shimming first. Shimming can sometimes affect the cutoff straightness too.

You can tell the Philips has proper alaignment, but you can also see the rotation is slightly off on your right projector

Finally got around to reading this thread - My car has H7 based halogen projectors, and I know for a fact they need to be shimmed. I know that alot of times halogen based projectors don't handle HIDs well, but I've played with bulb alignment and the output wasn't so bad.... The problem I am facing is is tuning it right. I really don't have any walls outside (I live in an apartment complex with ALOT of trees) and at the moment don't have a power supply to do it in the house.

I am thinking about going with morimoto bulbs, because they atleast have a form of quality control and alignment... so it would be a little easier to shim than the crappy innovited bulbs I have now.

It's been my experience that an improperly shimmed / aligned bulbs affects width, distance and foreground... So thanks very much for the thread.
