Headlight adjustment

[DizzyDevil]

PT just had new headlight assemblies put in at Tool Time on Sunday (Thanks to Tony.... )

that being said they are out of adjustment, so since the last time I adjusted headlights (on a 1966 Chevy Caprice).... there has been some changes like no headlight adjustment ring.

I looked it up in my handy online PDF Manual but it seems that you can take this in and have it done semi automatically.... Is this true? and suggestions on where to take it? dealership? Anyone know about how much it would run?

This is from the Hella website: It is geared more toward the installation of H-4 type bulbs which have a horizontal line and then a light line that goes up to the right which illuminates the right side of the road. Most of the aftermarket (or stock) lamps can be adjusted similar to this. If after you adjust them people keep flashing you thinking you have your high beams on, then they might be a little high.

How do I aim my European technology headlamps?

Set your correct tire pressure, full gas tank, and then park the car on a flat surface facing a wall, parking 25 feet away. Measure from the ground to the center of each headlamp and mark this spot on the wall. Measure the distance between the headlamps and mark this on the wall.(***) Turn the lamps on. Center the high beam on the mark on the wall. Stand behind the car and make sure the beam is parallel to the direction of travel of the car. Check your adjustment by switching to low beam. The low beam horizontal cut-off should fall about three inches at 25 ft. below your mark on the wall for the center of the headlamps. Finally, take a test drive, as aiming is partially a matter of personal taste and vision.

For driving lamps, aim them as you would your high-beam headlamps.

(***) One other thing, when using the method above, you will need to find the centerline of the car which for some reason they left out. You will need to find the center of the rear window and the front window and then sight through the 2 lines (use tape or grease pencil) to find your centerline on the wall. Then once you have the distance between the 2 headlights you can measure 1/2 the distance from the centerline to find your aim points and then measure distance from ground to center of lamp for cross reference.

I'm sure if you google "How to aim headlamps" you may even find some diagrams. It's not too hard to do and it will cost a lot less (FREE) than going to a dealer. Best to do it when near dark.
