hi I have a 06 Z with bi-xenon headlight and the light coming out from the driverside is lower than passenger side. does anyone know how to adjust it?

Thanks.

It's supposed to be that way. Like mc350z said so we don't blind oncoming vehicles.

You need a LONG phillips screw driver. At least a foot.

Problem with the factory settings are you can overdrive them at 30 mph.

From what I have heard, the procedure is the same for all Zs even though the fixtures are different.

Take a look at this http://www.hypersprite.com/auto/tech-z-003/index.asp

Nice article. Mine are a little low, but its not causing me any problems.

I used a 18" phillips (you'll need at least 10). you can adjust the height level.

thanks k3silk, I just installed some 06 lights and I have the same problem. You saved me the time to dig for this thread.

That is not the correct way to adjust projectors, as it doesn't take into account ride height at all. Also, 8 ft from the wall is too close to be able to properly adjust the aim because changes are too small in the projection at this distance. Using your headlight aiming guide for the actual adjustment, they should be aimed like this:

A.
This is your reference line, it is the distance between the ground and the middle of the projectors. Measure this distance with the tape measure, and transfer this to the wall, making a straight line parallel to the ground at this height with the masking tape. All your aiming is based off this line, so make sure it is straight and the right height

B. This is the amount of slope the headlights have to meet DOT specs. At 25ft, the lower step of the cutoff should be 2.1-2.5" below the middle of the projector, which is the reference line in red that you marked using the masking tape previously. Check each headlight seperately to make sure the lower step falls on this line.

C.
This is the distance between the projectors, and is measured between the centers of the two projectors. This distance on the wall is measured between the slopes of the two projector cutoffs. This measurement is to make sure the projectors are actually pointed straight ahead. Another way to make sure is to drive towards and away from the wall and see if the two angled slopes move left and right. If they aren't pointed straight, either loosen the headlight bolts and adjust them until they are straight, or remove the headlights and adjust the two 8mm bolts on the rear which adjust the horizontal alignment. This is a tedious process and will require multiple removal/reinstalls

D. This is the distance from the projectors to the wall as mentioned before, 25ft. This is the standard distance for measurement performed to meet DOT specs.

Make sure that the lower and upper cutoffs are even with each other and that they are parallel to the ground. If they are rotated/angled, its likely the way the headlights were installed, and you need to loosen the bolts and adjust them around until they are level.

This was for a g35, but its the same steps for any projectors. This way its relative to the projector height, and the 1.2% slope that is DOT specs is maintained
