TepEvan, I have found at night that the ground immediately in front of the car is way too bright... Has anyone noticed the same and found a solution? I am experimenting with tinted film on the bottom edge of the headlight to dim the light striking the road up close in front.

I would not be into film reducing the power of the light at all, I too live in deer country and these low/wide/bright lights are just great for picking up their eyes way off on the shoulder of the road!

The Honda specification is to measure from the ground to the small dot in the middle of the low beam.
Park the car 25 feet from a wall, turn on the low beams and measure the lower of the split horizon. It should be 2.1 inch lower than the dot on the headlight.
I did testing and found that a 180 lb driver will raise the headlights about 2 inches at 25 feet. 100 lbs in the trunk will raise the headlights about 2 inches at 25 feet. A couple on vacation will need to adjust the headlights a little lower.
A good rule of thumb is to have the "horizon" at the top of most cars bumpers when you are stopped behind them at a stoplight. If they are higher than that you may get flashed from oncoming traffic.

Bringing this thread back from the dead.
I been searching around trying to find out what measurements I should be adjusting my headlight to. The only information I can find is that I have to be 25ft away from the wall.
anybody?

If you are not used to driving with projectors and particularly HID projectors they SHOULD appear to be aimed too low because of the sharp cutoff.
DOT specifies that for HID projectors the cutoff line should fall 2" every 25' away from the front of the vehicle. This means that when you are on level roadway the cutoff will hit the roadway between 250 and 300 feet up the road. Now when going down dips in the road you will notice the cutoff MUCH closer to the front of your car. This just takes getting used to. If you aim them up too much you will blind every oncoming car.

Thanks for the infomation... but I'm still confused on where the cutoff should be if my car is 25' away from the wall.
I lowered substantially and I have also replaced my headlight with a new one. I can tell a big difference from now and when my car was stock.
