Aftermarket projector headlight aiming; available brands?
#22
Another installation glitch:
The OEM turn signal connector harness is just a bit too short to pull under the headlight assembly into the compartment. I can barely do so; but under the car, there is a spot where the wires are not in the plastic loom and they are pulled tight against a metal edge.
So I will route the 4 wires from the assembly under & out the light and leave the connector under the bumper. I wrapped them in tape against abrasion & to be neater in the compartment -- a loom is a bit thick to fit thru the gap under the assembly.
Also, the connector on the projector wires was shoddily potted; I can see bare wire. So I've gooped it up with silicone sealant.

Had them aimed by the mechanic and the low beam illumination is totally inadequate. It doesn't throw far enough forwards. If the ground rises its totally dark. Also there is no illumination at all to the sides; I'm making turns into complete darkness.
Are all machines really capable of correctly aiming this type of headlight?

I do have HIDs -- that's why I got the projector housings instead of replacing the OEM.
I want to at least use the machine to get it in the ballpark, and learn which way to turn the ***** to go up/down and left/right.
Today we put it on the machine again... sort of came to the conclusion that I need to shim both sides so they point rightwards, because the horizontal adjustor seems to be all the way over.
I'm wondering if the lamps are extremely far towards the driver's side horizontally, they are throwing the brightest part of the pattern in that direction instead of forwards. That would account for the low candlepower reading and maybe it is aiming too low in order to find the least-dim area ???
WRT vertical: I'm not sure the guy was using the machine properly. The top of the pattern was along the horizontal line. I would think that you want the center of the pattern on that line; but he said the machine tells him the number of inches off horizontal the pattern is, and that it needs to be adjusted to show at least 4" under. Still not convinced that the machine was built to properly calibrate this type of lens system.
Wouldn't the distance between the machine and the lens be critical? They just wheeled it over, without any measurement of that distance. Does the machine self-correct for being a random distance away, within certain limits?

Put in the shims. Also noticed that the horizontal part of the beam is not horizontal. Definite V pattern. Tried pushing down on the outside bolts to the bottom of the hole & up on the inner, but still a V.
Maybe these just don't fit the car correctly. ???

Don't have an accessible wall that far away. Have to clear stuff out to maneuver perpendicular to the garage & can back up to maybe 10 feet away. First need to decide if I want to try ovaling out the bolt holes so I can rotate the projector housing so that line is horizontal like it should be. No fun in the dark, chilly, wet. Yecch.

OK, got up in the middle of the night. Took a drive & the throw is pretty good forward; still not so great sideways.
The bulb seems to be 25" high from the ground.
The top of the left horizontal line at center is about 22" high.
To top of the right horizontal line at center is about 24" high.
I have to guess in the height at the wall because there is a "step & dip" to keep rain out of the garage; my guesstimate is a 2" difference in ground level, which I have subtracted above.
The front of the internal projector is about 12' 4" from the wall.
Driving towards this car, its pretty darn bright. But I don't get the sense that I'm being aimed directly at by the center of the bulb, if you know what I mean. Dunno.
I should have thought to stand at some distance and squat to different heights to see if I could find a significant cutoff in brightness. If that would work with properly adjusted beams ???
It will take some time to transfer photos from the camera to computer to upload...

Both, Left, Right headlight beam patterns 12' 4" away from the wall. You can see how the left is somewhat of a U curved shape instead of the crisp V. And the horizontal line is not. The right is fairly horizontal. All photos taken from the center of the dash

When you approach the lights and see a blue tinge you are seeing the top of the pattern, right? So at some distance I want that blue tinge to appear at the eye level of an approaching driver...
Had to crank the right light down some.
The upper right part of the left-beam has a definite dark spotty pattern, and it is very noticible above the brighter right-beam. Overall dimmer would be fine, but this random dim & dark prevents me from seeing things.

The blue is fine. That does not look correct. Check your bulbs. Put your halogen bulbs in and check to see if the beam pattern is the same. I know that is not correct. I still have my projectors if you want/need them.
And also, the V does not need to be the same. They are supposed to be pointed foreward. This is what is should end up looking like.
