So after getting my retro's, I did a lot of searching and asking question's to find the way to aim your headlights. After awhile I was able to figure it out, thanks to Yodums for all the help aiming and to J-Ro for building an awesome setup and also helping with aiming!! :clapping:

So I thought why not make a thread for it instead of trying to piece together a bunch of answers. Hopefully this will help anyone trying to do some aiming.

So here are the measurements: :dancing: (These are more exact for projectors but can also be used for just regular halogen or hid bulbs)

Honda Specs:
1. measure vertically the ground to the centre of the lens
2. multiply that number by 0.9
3. measure 25ft forward from the centre of the lens
4. measure vertically from the ground to the cutoff at 25ft. Your objective is to have the cutoff at the height calculated in Step 2.

In other words
- Find a [near] perfectly flat surface with at least 30ft of room and a wall
- Measure the distance from the ground to the middle of your projector bulb (Mine is 25")
- Mark with tape on a wall that distance minus 2". So, 23" for me.
- Back your car up 25' (Distance is from the wall, to the projector bulb).
- Adjust the drivers side headlight cutoff (very top) with mark on the wall.
- Adjust the passenger side headlight cutoff to match drivers side.

As for some pictures:
Tools needed 6-8 inch phillips screw driver like this

and a flash light (because you should be doing this at night so that you can see the cutoff on the wall properly)



^This is the adjustment piece. Works like a gear when you turn the screw driver.

Then this is the area your going to be working in.


Closer up view


^That little hole is where your going to be sticking the screw driver down. Now it's a little hard to see, but really if you follow the hole it pretty much guides you right into the gears that was circled before. Both sides are the same, it's just a little harder to see on the drivers side because of the battery.



^As you can see there are guides that direct the screw driver into the gears.

Now that you have caught the gears with the head of the screw driver you turn it CLOCKWISE to move the light up and COUNTER CLOCKWISE to move it down, to line it up with the measurements you did previously. (NOTE- Do not turn the adjustment peice to far as it will eventually stop and break. If you do not see the light getting lower or higher you've hit the limit that the lights can be adjusted too.

So I hope this helps somebody out and maybe it will get turned into a sticky i don't know. If anyone has anymore questions or would like to see some more pictures of a specific thing feel free to ask. :dancing:

The final outcome.

So this will work for adjusting for a PnP kit as well? I have a DDM Tuning 5000k kit coming in the mail soon and I want to make sure I properly aim my headlights after the install. Great writeup BTW.

Yeah i'ma subscribe cause i'm getting my HID's soon for my OEM headlights and I MAY have to readjust the headlight beam to reduce the glare for oncoming drivers. Thanks for this DIY.

yes this works for just regular pnp kits. the specs are from honda, it's just with a projector it is obvious where the cut off is. a little harder with just a pnp, but you can limit the amount of glare above the line you make on the wall. glad this is helping some people :dancing:

hmmm, after install my ddms and letting my friend drive my car behind me...it doesn't blind ppl too much with stock aiming. But I might lower it a bit.


edit: thats the most insane cut off I've ever seen. Wonder what can do that.

I did a search and found this and Im glad I did. It saved me a bunch of time figuring it out myself. My headlights were WAY misaligned.

Someone with PnP, show me pics of your headlights aimed down at the ground.

I really don't think there is any point in adjusting them from OEM aiming. (You won't pass inspection if they are aimed too far down, for one)

With projectors, you have an actual projector which is tilted up and down, but with reflector housings, it doesn't quite work the same way.
