Assembly. Remove any existing mounting adapters.

3. 28 VDC (+) and (-) ground leads equipped with an appropriate
sized breaker to be supplied to the LED Flashing Split Anti­collision Light Assembly System. Both leads must be connected
by an approved FAA connection. Insure that the wire leads are
clear of any obstructions and ty-wrap as required.

4. Install the light assembly by first removing the lens. Remove the
adapter plate. Attach the adapter plate to the aircraft mounting
holes. Refer to page 2. Reinstall the light assembly and lens.

5. All inverted (bottom) mounted units shall require waterproofing of
the flasher base assembly to the aircraft. Note: Drill a 1/8” hole in
the center of the lens for bottom mount units.

6. Check all avionics systems for interference from this installation.

7. A flight check should be performed by a properly certified pilot.

8. Update aircraft records, complete Form 337 and obtain FAA field
approval for installation, as required.
