OPERATING INSTRUCTIONS:

Operational Voltage: . . . . . . . . .28 VDC

Average Input Current: . . . . . . .0.35 Amps

EQUIPMENT LIMITATIONS: An approved forward
position lighting system consists of two lights, one located
on each wingtip, mounted at a minimum of 4” from the
leading edge.

CONTINUED AIRWORTHINESS: The 70875 series LED
wingtip position light assembly is designed with 7 LED’s. If
any one LED fails, the unit must be repaired or replaced.

INSTALLATION PROCEDURES: The following
information is to assist in the installation of a Whelen LED
Forward Position Light System.

Choose the appropriate 70875( ) series replacement
light assembly.

The installation procedure described in the
following text will be confined to a single light
installation, but is identical for multiple light
installations.

Remove the old light, locate and save the existing
+28VDC lead and (-) ground lead. Clean and prep
ends as required.

Make sure the existing system is equipped with an
appropriate sized breaker. Connect the existing
+28VDC lead to the 18 AWG wire on the input cable
assembly (supplied with the light assembly). Connect
the existing ground lead to the black 18 AWG wire on
the input cable assembly. 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.
The pressure venting tube may be trimmed to a
minimum length of 1” from the base.

Remove the two #6-32 x 1¼” screws and remove
lens from the LED position light assembly. Retain the
screws and discard the hex nuts.

Position the base of the new light assembly onto the mounting
surface. Insert a #6-32 PPHMS from the previously installed
assembly into the rear-most mounting hole and tighten firmly.

Secure the lens onto the base with the #6-32 x 1¼" screws
referenced in step 5. Tighten these screws until lens bosses
bottom on the LED module.

Check all avionics systems for interference from the installation.

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

10. When necessary, waterproof the assembly to aircraft. Apply

aviation approved single part silicone (RTV) or equivalent
around any open area where water could get in.

11.

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