After installing my new OEM HIDs i was wondering whether this is the proper beam cutoff.
the car in this photo was sitting on a level surface about 25 feet away from the wall.

the following two photos are a comparison between my halogen Sylvania Silver Star capsules and the HIDs in the second (camera settings were identical in both photos, shutter, aperture, ISO, etc.)


the only reason i ask, is because i couldn't really find any photos of cutoff beam patterns on the net to compare them to.
the only awkward thing with these OEM HID units i've noticed is that the high beam seems to be offset at a slight angle to the left. i guess i'll have to adjust those separately.

Pattern looks fine to me.
You didn't happen to take any comparisons of the high beams did you?

Re: HID beam cutoff (dennisgli)

thanks, by the way guys, do any of you have any info on how to make the low beam Xenons stay on when i turn my high beam halogens on? when i jerk the stalk back to flash the beams, it works fine, but when i push it down my low beam HIDs turn off.
i know there was a post somewhere about running a cable from the center console to the light switch, but i was looking for more of a simpler approach.

Amazing difference between the stock and the HID set up. Great comparison pics. http://****************.com/smile/emthup.gif

I did it like this, it's really simple http://****************.com/smile/emthup.gif

Re: HID beam cutoff (daniel.ramirez)

the only issue at this point is the high beams which seem to be offset to the left a few degrees.
i have realized that the adjustor screws not only adjust the projector low-beams, but the whole unit as a whole, including the high-beams.
the problem seems to be that low-beams and high beams are not aligned as you see in the below photos:
this photo was taken with the low-beam HID on (the black dots was where i put black tape as a reference point).. and sorry for the pic quality, only had my phone with me.

now as for what the pattern looks like with the high-beams on as well:

as you can see the high-beams are offset to the left quite drastically.
even when i drive on a dark road at night, my low-beam HIDs illuminate the road evenly, but when i turn my high beams on, they seem to point off to the left by about 2-5 degrees or so.
so i tried adjusting them with the adjustor screws, and got the high beams to point straight ahead, but then, inherently, my low beam HIDs were offset to the right.
i wonder why this is, considering they are brand new factory HIDs. perhaps the high-beam capsules are loose? they certainly don't seem to be.
pity there aren't separate adjustors for the high-beams.

Are you saying that the two bottom "dots" in the picture are not straight ahead of the car?

Re: HID beam cutoff (dennisgli)

those dots represent where the low-beam HIDs project their light. in the second pic you'll notice the bright oval areas lit up by the high-beams being quite off to the left instead of in-line with the low-beams, which are lined up directly ahead.

If I look at the lower left "dot" it looks like the left high beam is higher (which it should be) and to the right of the dot - not too the left. Or do you see it differently? The right high beam does seem to be to the left - maybe that light is defective?

Re: HID beam cutoff (dennisgli)

yes the left high-beam seems to be fairly within the acceptable range, it's really the right high-beam that is really offset to the left.
when i aimed these lights i only did so vertically, and only used an educated guess as to how far apart they should be horizontally.
i'll re-aim them this weekend and take measurements, both vertical and horizontal and see if i can get that right high-beam where it should be. not that i use high-beams in NYC much anyway, but having dropped almost $1200 i'd prefer to have them working properly

Re: HID beam cutoff (advocatexxx)

You say that these are factory HIDs - and then you mention high-beam capsules. I thought the factory HIDs had tungsten bulbs for the high beams?
You can't tell from the pictures where the centerline should be and how far apart the beam patterns should be. If the bulbs/capsules are seated correctly in the lights then you should be able to get them aimed properly. But I've never seen these lights - does the HID projector bolt on to the rest of the headlight - maybe that isn't mounted correctly?

the HID low beam projectors are part of the whole headlamp unit as a whole. they are not adjustable independently from the rest of the headlamp. and yes the high beams are separate halogens.
