SELF CONTAINED LIGHT ASSEMBLIES
MODEL 71055 ( ) SERIES LED BEACON
ANTI-COLLISION LIGHT ASSEMBLY
71055 series beacons are FAA TSO compliant self-contained LED Anti-Collision lights.
They are designed to replace existing quartz halogen flasher beacons installed as original
equipment on single engine Cessna's from 1967 and later (contact factory for details). They
can also replace remote mounted strobe lights (ref. Whelen Aerospace A470 series) allowing
for removal of the strobe power supply. Internal mounting plate provided with choice of mount-
ing holes to retrofit most existing mounting patterns. STC SA615EA approved.

Operation
Equipment Limitations: The Model 71055 Series LED anti-collision
light assembly meets or exceeds the requirements of FAR 23.1401,
and FAR 91.205(c)(3).
Continued Airworthiness: The 71055 Series LED anti-collision light
assembly is designed with 6 vertical columns consisting of 2 or 3
LED's each. Should any one LED or any vertical column fail, the unit
must be repaired or replaced. Periodically inspect the lens and
replace if there is excessive scratching, discoloration or cracking.
Installation Procedures: The Model 71055 is a self contained flash-
ing beacon that requires no external flasher or power supply. In some
installations, it may be necessary to remove several existing compo-
nents. When replacing flashing halogen beacon assemblies, the
flasher box and ballast resistor (if present), and associated wiring,
need to be removed. When replacing strobe light assemblies, the
strobe power supply must be removed. In both cases, 18 gage DC
voltage wires, A+ & Ground (-), must be continued from the location
of the previous box, (flasher or power supply), to the location of the
new LED beacon.
The following information is to assist in the installation of a Whelen
Aerospace LED Flashing Anti-Collision Light System.
1. The installation procedure described in the following text will be
confined to a single light installation, but is identical for multiple light
installations.
2. Using the "suggested mounting hole pattern" prepare the aircraft
for means to secure the LED Flashing Anti-Collision Light assembly.
Remove any existing mounting adapters.
3. 14 / 28 VDC (+) and (-) ground leads equipped with an appropriate
sized breaker to be supplied to the LED Flashing Anti-Collision Light
Assembly System. Both leads must be connected by an approved
FAA connection. Insure that the wire leads and the pressure venting
tube are all 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. Check all avionics systems for interference from this installation.
6. A flight check should be performed by a properly certified pilot.
7. 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.
8. Update aircraft records, complete Form 337 and obtain FAA field
approval for installation. If not covered under STC eligibility list.
