    Aiming Headlights

    Does anyone know the correct criteria in aiming the headlights for the Rex i.e. how far from a wall should the car be, how high off the ground should the headlights come up, and how wide apart should the lights be when measured from the center of the beam. I tried this website:http://lighting.mbz.org/, but it doesn't seem to have anything under aiming, I think the site is messed up or something. Can anyone help me out?

    Thanks!

    Thanks for your help...but I already knew about the level switch, and I do have JDM STi LHD headlights, and that is why I am actually at the point I am at right now. When I put my lights in, they were crooked, and I needed to fix them. And in order to get the level switch correctly working, the headlights have to be in proper position before hooking them up. So I just need a good criteria to follow to get my headlights on proper target. So if you know of any, it would be much appreciated. Thanks for you help!

    I've haerd 15 to 25 feet.

    Find the center locations for the low beams....translate them on the wall...the bright spots should be in the area.

    Here's instructions I found on a VW forum. I think my CRX service manual might have a drawing. I'll look later.

    >>> Headlight beam adjustment for left-hand-drive Beetles and Buses


    Tools required:

    1 screwdriver (1966 and earlier Beetles and 1967 and earlier
    Buses, slotted. 1967 and later Bugs and 1967 and
    later Buses, Phillips.)
    6 feet of butcher's paper, approx. 2 foot in width
    1 roll of making tape
    1 felt tip pen or marker
    1 adult assistant (approx. 150 lbs.)
    30 feet of nylon cord
    1 measuring tape (25 feet)
    A few pages of a newspaper (or other material to cover headlamp)

    Proper headlight beam alignment is necessary for the safe operation
    of any automobile. Elements such as wear-and-tear and headlamp replacement
    both contribute to the misalignment of the headlamp beam. Most automobile
    repair facilities are capable of aligning your car's headlamps; but we think
    the task is simple (and much easier on your pocketbook!!).

    Before you begin, check all four tires and inflate to the proper
    pressure. Park your car on a level surface area with the headlamps 25 feet
    from a vertical wall. From the exact center of the headlight, measure this
    distance to the ground. Attach butcher's paper to the vertical wall, keeping
    the distance (headlight to ground) in the approximate center of the paper.
    Using your marker, draw a horizontal line (the measurement from the headlight
    center to ground) across the entire length of paper. We will refer to this
    line X.
    Using the nylon cord, have your assistant hold the cord at the exact
    center of the left headlight. Extend the cord outward towards line X,
    following a straight path. Mark the point of the straight line formed by the
    nylon cord onto line X. At this location, draw a vertical line the entire height
    of the butcher paper. We will refer to this as line Y. Perform the same
    procedure for the right side. Label this line Y as well.
    Measuring 2 inches to the RIGHT of BOTH Line Y's, mark a vertical
    line intersecting line X. We will refer to both lines as A. Cover the right
    headlamp with newspaper (or other material). Have your assistant sit in the
    driver's seat of the car, and turn on the headlamp switch. Make sure the
    headlamps are set to the low beam position. Observe the light reflection on
    the butcher paper. A properly aimed beam has the upper edge of its high
    intensity zone on the horizontal line X, and left edge on line A. Adjust left
    side if necessary.
    To adjust beam, turn the screws located on the outside of the
    headlight rim for 1966 and earlier Beetles and 1967 and earlier Buses. For
    1967 and later Bugs and 1968 and later Buses, remove the chrome headlight
    rim. The adjusting screws will be located on the headlamp housing at the 12
    and 9 o'clock position.
    Remove the paper from the right headlamp and attach to the left side.
    Follow the same procedure for right headlamp beam alignment.

    IT would seem to me that the farther from a wall you were, the most accurate your aiming would be.... Im not all that concerned with how my headlights illuminate the road 30 ft in front of me.... but more like 100 ft plus, since this is the distance i will need to being seeing things in order to react to them at speed.... So what i generally do is go to an empty parking lot with a building at one and and get nice and far from it - and aim at the wall that way.

    just my thoughts,
