Nelson, Hugh - As a one-time headlight lens designer from a past life,
the aiming procedure for the headlights in this website is applicable
for european style halogen lamps. If you have them, then this is an
excellent procedure. If you have run of the mill round headlights from
Sylvania, GE, etc, then this procedure needs to be modified since US
headlights tend to produce a spot at 25 feet, not a horizontal spread of
light that is typical of european headlights. I would follow the basic
procedure but before backing the car up, I would also make a vertical
line for each headlight corresponding to vertical centerlines of the
headlights. Back up the car and aim each headlight so that most of the
spot is to the right of this line, and below the horizontal line.
You can also check your high beam aim, which should ideally wind up
going right down the middle but rarely is this the case. Unfortunatley
with single low/high beam headlamps there is usually a wide separation
between low and high beam aim. You can try to strike a compromise by
adjust the low beams a little down and right, but bear in mind that if
you are like me the high beam is usually not used often. In my case I
go for best low beam performance and let the high beam go where it will.
