3. Connect the black (–) wire from the search light to a known
good vehicle ground as close to the unit as is practical.
Permanently Mounting
To permanently mount the search light:
1. Scribe the locations of the three mounting holes on the
mounting surface using the desired mounting holes in the
flange or base as a guide.
There are two sets of evenly spaced holes 120° apart on the
bottom of the search light itself. Holes for the #8 self-tapping
screws are on a 2.75-inch diameter (where the lines intersect
the inner circle in Figure 3). The holes for the #10 self-
tapping screws are on a 4-inch diameter (where the lines
intersect the middle circle in Figure 3). The 4-inch pattern is
the preferred pattern for permanent mounting.
If one of the optional mounting flanges is to be used,
three #10 screws are on a 6.00-inch circle (where the lines
intersect the outer circle in Figure 3).
