W: Distance between each headlight
center
L: Distance between the headlights
and the wall that the lights are
tested against. 7.62 m (25 ft)
C: Distance below the horizontal cen-
ter line of the light (“H”) used in
determining the main axis of light.
106 mm (4.17 in)
H-C = M
M
= main axis of light
Even if the horizontal indicator does not
align with the indicator line or the bubble is
not centered in the water level after aiming
by the chart, it is acceptable if the lines are
within the OK ranges.
