EQUIPMENT LIMITATIONS:
An approved forward position lighting system consists of three lights,
one located on the tail and one located on each wingtip. Model
OR650( ) is a wingtip forward position and anti-collision light.The
assembly should be mounted as far outboard on the aircraft as
practical. The baseplate must be mounted parallel to the vertical and
horizontal centerlines of the aircraft to project the patterns properly.
Certain types of installations may require additional testing.

CONTINUED AIRWORTHINESS:
The forward position light is designed with Green or Red LEDs. The
anti-collision light is designed with 18 white LEDs. If any one LED fails,
the unit must be repaired or replaced.
Inspect the lens, replace if there is excessive scratching, pitting,
discoloration or cracking.
Note: To reduce eye strain, use an optical filter such as dark glasses
or a blue covering dome during LED inspection.

INSTALLATION PROCEDURES:
The following information is to assist you in installing a Whelen light
system.

Choose the appropriate light assembly.

Using the mounting detail information provided, prepare the
aircraft for means to secure the light assembly.

Carefully remove the #4 phillips head screw and lens retainer.
Remove the lens from the light assembly by lifting the rear of the
lens approximately 1/2”. Now slide the lens rearward
approximately 1/4” and lift upwards to remove. CAUTION! To
avoid potential damage, do not touch the LEDs with either
fingers or sharp objects.

Remove the 6-32 hex nut and washer from the stud on the
underside of the mounting adapter. Remove the ground strap off
the stud. Remove the 3 Phillips head screws securing the
baseplate to the light assembly. Remove baseplate.

Using the appropriate hardware install the baseplate directly to
the aircraft.

Route the wires through the opening in the baseplate. Connect
the light inputs according to the chart shown. Connect the power
lead to an appropriately sized breaker. Connections to be
according to FAA approved methods.
Note: SYNC is a low-power, bi-directional control signal.
Connecting to the synchronize signal of any Whelen LED anti-
collision assembly to another Whelen anti-collision assembly will
cause the lights to flash at the same time. If Synchronization is
not necessary, the connection may be left open.

Reconnect the ground strap to the mounting adapter and secure
using original hardware. Tighten until a maximum torque value of
9 in-lbs is achieved. WARNING: Do not overtighten!

Re-install the light assembly on to the baseplate and insure that
all leads are clear of any obstructions and secured as required.
Note that proper orientation is achieved with the drain hole down.

Install lens in the reverse order as removal and return the lens
retainer to its installed location. Note: Visually confirm that the
lens and retainer are fully and properly seated. Re-insert #4
phillips head screw and tighten firmly.

10. When necessary, seal the light to the aircraft. Apply sealant

around the perimeter of the base. Do not cover the drain hole.

11.

Check all avionics systems for interference from this installation.

12. A flight check should be performed by a properly certified pilot.
13. Update aircraft records, complete Form 337 and obtain FAA field

approval for installation, if required.
