Any tips on adjusting headlights?

I've read to park in front of a wall and mark the center then backup 24' and set the up/down to be 3" lower and the left/right about straight on. I got a set of LEDs.

 

i just parked on a nice flat dead end road in the middle of the night, and adjusted them until i had them where i wanted them on the actual road, i pushed them out slightly farther than the original ones were, which was kinda too close.

Adjust it a little one at a time while covering each one to adjust them vertically until i got them where i liked them, and then uncovered them to make the tiny adjustment so they were symmetrical.

Took me about 15-20 minutes or so to get them just right.

It helps if you have a helper to stand in front of the left, then the right so you can compare them while adjusting.

 

First if you have reflectors housing take those LED's out, its unsafe for other drivers.

For adjusting low beam headlights your goal is for the top of the beam hit 300ft (according to the IIHS).
Step one will be measure the top of the beam right at headlights from ground, for this example we will say that measurement is 30".
Now divide measurement in step one by 300ft, this will give your factor to determine what height the top of the beam should be at a set distance. For our example 30÷300=.1
Step three after finding a flat spot/wall. Measure your distance from headlights to wall and multiple your factor. We will use 10ft from wall for this example, so 10 feet times our factor .1 equals 1.
We will now subtracted the number from step three by our measurement in step one. 30-1=29. This gives goal for top of beam of 29" at ten feet away from the wall.

Lets use the same height in step on but change how far we are away from wall, 30ft. 30ft times our factor would = 3. So 3 from 30 would equal 27. 27" would be our goal for top of beam if we parked 30ft from wall.

This will give us the best IIHS range while not wasting.

 

I go behind Home Depot at night with a tape measure and blue tape and use s flat level space and tape out the grid on their wall.

 

Aim them where you want them and then take a night drive on a two lane road. Adjust them downward to a point where no one flashes you and you’re set.
Sounds like a redneck solution, but it works for me. Get as much light down range as possible without pissing anyone off.

 

And when you need to flash someone else who has stoopid brights, thats what the 780w LD light bar on the roof is for.
