Interesting pdf! Was that 1/2 inch at 9.84 feet, or 25 feet? Did you notice a great improvement on the road, afterward? How many turns do you estimate it took to move it 1/2 inch?
I'm definitely going to mess with mine; my low beams are pretty bad.
Thanks.
1/2 inch at the 9.84 ft. I have the marks on the garage wall and a spot marked on the floor to set the distance. I can make a quick check by just driving into the garage. I think lot of cars are shipped with the lights set too low based on the number of complaints I've seen. Just setting to spec makes a big difference. It takes several turns of the screwdriver to make much difference, but you don't want to over do it. It's best to cover one of the lights with a cloth while adjusting the other one. I set the right side a little higher than the left and it helps a lot to see road signs, etc.
I've always been picky about headlight alignment and usually end up with the best for vision, without getting flashed by other cars on the road. That's kinda the ultimate test. Set the lights and then go out and drive at night, then set again if need be. Probably 8 out of 10 cars on the road need their lights adjusted. Most people just don't pay much attention to that, and I doubt that most car dealers actually check during predelivery inspection.
