In the dark

I have just finished my first night trip after adjusting the headlights down. It was much better. I used 10 turns down from the factory setting. Low beam was ok for up to 55. High beam was acceptable. Perhaps Santa will deliver HID. AL

Yep, I found it necessary to adjust my headlights down also. I used a 5/32" Allen wrench and it worked fine. Only one adjustment screw on each lamp.

I just pulled it in front of my garage door with lights on so I could gage the amount of adjustment. It's so easy you can just try it out and adjust more or less to your liking after you drive it some.

I have not seen any angry driver(s) in front or around my Hummer, and no one ever flash me, certainly no finger, but many thumbs-up, but after so many of you reported having head lamp problem I decided to adjust my head lamps down a bit. As you said, it is super easy, the adjustment is outside by the lamp, very unusual to me, maybe this setup is common on trucks/SUVs? All other cars I have/had adjustment is inside the hood.

Question: on the road, how far ahead the light should cover the ground? I did the adjustment against the garage door, but during a test drive, I felt the light maybe too low. Do you have some measurement or words of wisdom on this subject? Example, if H2 is 10' from door, where should the top edge of light be? 4' from ground? this may not work, because any small incline on my/your garage approach will influrence the light height.

or else, I can go for a drive with my wife driving H2 following me in Jaguar. Seems troublesome but maybe the best true test.

Government standards measure the headlight adjustment at a point only twenty five feet in front of the car, and allow a tolerance of about four inches in any direction from center.

However, a four inch vertical error at 25 feet becomes a four foot vertical error at 300 feet in front of the car. I've heard that 300 feet is considered the critical point of illumination. You should be able to clearly see a man, an animal or a parked car at 300 feet. Aimed just four inches low at 25 feet and you loose about 50 percent of your illumination and four inches high can blind on-coming drivers.

Vehicle inspection locations should be able to check it for a few bucks.

That's good stuff, Red. I adjusted ours down.

I added four lightforce driving lights that are so bright they vaporize bugs at 10 feet.

If they don't like my headlights, they quickly learn that there are worse alternatives....



BOOWAHAHAHAHA.... Love them Lightforce Lights!
