A625 Strobe Light Assembly
The A625 strobe lighthead assembly fits into a 1.1 inch hole. The mounting
screws are 1.75 inch center to center. It protrudes 1.7 inch outside the air-
craft's skin, and 1.1 inch inside the aircraft.
When installing an A625 strobe lighthead assembly on the rudder, refer to the
aircraft's MAINTENANCE and/or SERVICE MANUAL for accepted procedures
3 8
for balancing the rudder before returning the aircraft to service.
Mount the anti-collision strobe lighthead assembly as close to the stabilizer
center line as practical, to eliminate backscatter as much as possible for the
horizontal surface.
4
When installing the A625 strobe lighthead assembly in an enclosed area like a
1
Beech enclosed wingtip or tail cone, maintain at least 0.060 inch clearance
around the lens to the plastic cover. The A625 mounts conveniently just behind
2
the forward position light on Cessna's conical camber wingtip. Make sure that
the navigation light pattern is not interrupted when installing the A625 strobe
light head on a wingtip. The A612 lens is not considered an obstruction.

A625 INSTALLATION IN CESSNA 300 OR 400 SERIES WINGTIP TANKS. The
A625 fits just under the navigation light, on an adapter plate of 0.032 inch
aluminum, approximately 2-3/8 inches x 3-1/2 inches. Fit this plate between
the navigation light and its mounting surface, and locate the A625 strobe head
below the navigation light.
Bend and trim the adapter plate as necessary, so that the A625 clears the
transparent window that covers the navigation light area 0.060 inch minimum.
The conduit for the navigation light wire is very small. To get the necessary
wires to operate the strobe light and the navigation light through this conduit,
use a 20 gauge wire, with less that 0.060 inch OD. It has been found that the
Belden 8502 or 8308, has an 0.058 inch OD.
