you only align one pattern, as by law, the
other pattern must be within 1.5” of perfect
alignment.

selected. The most inner portion of color is the high
intensity zone and this is what you center over the white
designated for the lamp pattern selected.
NOTE: Graphics on aiming screen denote position
of lamp position in inches.
6. Repeat steps for remaining lamps.
