Aiming my headlights

[Blast47]

First - I searched... so if you find the answer to my question searching, don't flame - just point.

I recently hightowered my headlights, but when I put them back in, I noticed they were not aligned properly anymore. From going through searches, I derrived using the bubble levellers built in, was useless. I am just not too sure as to how to adjust the headlamps using a wall etc. I know how to make the adjustments, just not sure what they need to be at for optimal viewing (so I don't blind other drivers by being too high, etc)

SO, with all that said - any pointers on how to use a wall to properly line up the lights? (how high/low should they be aimed, what to aim for, etc)

Dude, I'm having the same problem since to put my HID's in....the best luck I had was to get on a road with no traffic and well marked lanes. If you have halogen bulbs I would try to get the light to emitt about 20-30 feet, which is my judgement. I don't know if this will help too much but whatever.

The general aiming guidelines are pretty simple.

1) Pull up to a flat level ground wall
2) measure from the ground to the center of the lenses (low beam) there is a little circle molded to indicate the focal center
3) Measure the same height on the wall and mark it off with tape.
4) find a center reference point (the ford logo on stock mesh is a good starting point.
5) Mark that spot on the wall
6) Measure from that center to the little molded circle on the lense
7) Transfer those measurements to the wall
8) Back your car up from the wall roughly 25-30 feet (staying straight on against the wall!)
9) Measure down 2.5 to 3 inches from the horizontal line you have. Make a new line
10) Turn your lights on and see where they fall. The headlight output has a really funky hotspot that should be used as your center point of reference.
11) line your hotspots up with the vertical indicators you made, and the lower horizontal line

done? should be... drive on the road and see how it feels, if you're getting flashed they are probably too high.

That's what those little dots are?! I was wondering if they were imperfections or something while I was doing the hightowers but they looked like they belonged . heh.

Seems simple enough, thanks for the detailed info. Much appreciated.

Very useful info, I have been wondering about this for a long time.

no worries, let me know if anyone has any other questions

Not to completely flame, because you probably didn't find anything on ceg, but you could have google searched. I know I've found the info on the web somewhere!

Eh, I totally didn't think of that

I guess I figured coming from someone here would be better off since you guys know a lot about our own cars etc.

Strange that the Haynes manual for my wifes Intrepid has alignment instructions, but the manual for the Contour does not. I think it states the lights should be around 5" lower at 20'. Found the same instructions on an Audi site too.

5" at 20 feet will terminate the beam too soon.

3" at 25 is the euro spec aiming method, and I have found gives the best tradeoff between output and disturbing the peace
