Re: Headlight aiming
Thanks I will give it a try. I just would like to know what **** on the headlight assy. does what. We have projector headlights. Some of them need to be adjusted in a different manor. There are 3 adjustment screws on each Assy.

First, i can see to find the proper seating for these bulbs. I see there is a short tab at the bottom of the ring on the bulb and that slots into a slot in the head lamp fixture. However, its not what you would call "precision" it can vary up and down. If i'm going about this wrong can someone advise?

Re: Headlight aiming
Hope this gives the information you need.
Headlamp Alignment Preparation
HEADLAMP ALIGNMENT PREPARATION
The Headlamp Unit is a housing that integrates separate bulbs for low beam (3) and high beam (1) headlamps. It also includes the turn signal bulbs (2) and front position bulbs (6). The low beam, high beam and turn signal bulbs are enclosed with access covers for protection. One single harness connector (5) supplies power from fuses within the Illumination Control Module/IP fuse block, and ground. The entire Headlamp Unit is mounted onto the front of the core support structure and aimed with built in adjustment screws (4).
Headlamp Alignment Preparation
HEADLAMP ALIGNMENT PREPARATION
- Verify headlamp dimmer switch and high beam indicator operation.
- Inspect and correct damaged or defective components that could interfere with proper headlamp alignment.
- Verify proper tire inflation.
- Clean headlamp lenses.
- Verify that luggage area is not heavily loaded.
- Fuel tank should be FULL. Add 2.94 kg (6.5 lbs.) of weight over the fuel tank for each estimated gallon of missing fuel.
- Position the vehicle on a level surface perpendicular to a flat wall 7.62 meters (25 ft.) away from the front of headlamp lens (NOTE: If necessary, tape a line on the floor 7.62 meters (25 ft.) away from, and parallel to the wall).
- From the base of the wall, measure up 1.27 meters (5 ft.) , and tape a line on the wall at the center line of the vehicle. Sight along the center line of the vehicle (from rear of vehicle forward) to verify accuracy of the line placement.
- Rock vehicle side-to-side three times to allow suspension to stabilize.
- Jounce front suspension three times by pushing downward on front bumper and releasing.
- Measure the distance from the center of headlamp lens to the ground. Transfer measurement to the Alignment screen (with tape). Use this line for up/down adjustment reference.
- Measure distance from the center line of the vehicle to the center of each headlamp being aligned. Transfer measurements to screen (with tape) to each side of vehicle center line.

Re: Headlight aiming
I put in my McCulloch HIDs yesterday, and can't see S&%T! I tried taking the bulbs back out and making sure they are seated properly, and even with my trusty Mechanics Mirror, they damn sure look like they are in right. They feel like they are in right. The lights, however light up the group right in front of the car, and only about 15 feet in front of it. Has anyone else had this problem? I've tried three times to get them, and I'm fairly certain they are correct. Hopefully i can adjust the light up enough to see.

Re: Headlight aiming
OK, NOW I'M REALLY FRUSTRATED!!!
I went back and re-installed the HID Bulbs today, and yes, i finally got them in correctly. That's all well and good. Well, knowing me, I couldn't leave well enough alone...
I decided I still wanted them a "little" higher. No problem right? The Adjustment **** is right there and easy to adjust right? Yeah, well it was for the passenger side. Got that one no problem.
The Driver's side is another story. First off it's harder to get to. I actually put a 12mm ratcheting combo wrench on it, to make life easier, and so I didn't get that NASTY black adhesive all over me. Well, apparently, the adjustment **** needs to be turned the opposite way than the passenger side to get the same result. I didn't realize this until the aim was angled DOWN as far as it would go(I thought nothing was happening) . Ok, no problem. Turn it the other way right? No such luck. THE WHOLE FREAKING ADJUSTMENT SHAFT CAME OUT OF THE HEADLIGHT ASSEMBLY!!! EVEN THE SQUARE PART THAT IT THREADS INTO!!!
Anyone else have this lovely problem? It looks simple enough to just screw back in, but I can't get it in. I guess I'll have to start pulling stuff out of the car so I can actually get to it and pray it will go back in. HELP ME IF YOU KNOW A SECRET!

Re: Headlight aiming
I had a ***** of a time seating my HIDs, I was getting a horrible pattern but the only way to really get it right is to adjust them at night time with the lights on in a dark area, not the best way to do it since it's really tight in there. It was a real PITA but now there's a nice even pattern over the road.
I also adjusted my lights a little higher to get rid of the purplish edge of the light pattern that would shine on the road. So far no one has flashed their lights to tell me to put my high-beams off so I think I'm good and I can see a really good ways down the road (especially reflectors).
