POSITION LIGHT:

Operational Voltage: . . . . . . . 28 VDC (nominal)

Input Current: . . . . . . . . . . . . . 0.25 Amps

EQUIPMENT LIMITATIONS: A lighting system

consists of two lights, one located on each wingtip.

The baseplate must be mounted parallel to the

vertical and horizontal centerlines of the aircraft to

project the patterns properly. The strobe tube

assembly must be connected to a strobe power

supply, such as Whelen model 70888, 70879 or

other approved models.

CONTINUED AIRWORTHINESS: The 71172 series

LED wingtip position light assembly is designed with

3 LED’s. If any one LED fails, the unit must be

repaired or replaced. Inspect the lens. Replace if

there is excessive scratching, discoloration or

cracking.

INSTALLATION PROCEDURES: The following

information is to assist in the installation of a Whelen

71172 LED Forward Position Light/Strobe System.

1. Choose the appropriate 71172( ) series

replacement light assembly.

2. The installation procedure described in the

following text will be confined to a single light

installation, but is identical for multiple light

installations.

3. Remove the old light, locate and save the

existing +VDC lead and (-) ground lead. Clean

and prep ends as required.

4. Make sure the existing system is equipped with an

appropriate sized breaker. Connect the existing +28

VDC lead to the POSITIVE wire on the input cable

assembly (supplied with the light assembly). Connect the

existing ground lead to the GROUND wire on the input

cable assembly or use the supplied connector as shown

in the illustrations. 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.

Connect the strobe, J1, to the strobe power supply as

shown in the figure.

5. Remove the shroud from the light assembly.

6. Position the base of the new light assembly onto the

mounting surface. Insert three (3) #6-32 pan head

screws into the mounting hole and tighten firmly.

7. Reinstall the lens so that the two notches are positioned

under the shroud, with each notch equidistant to the

centerline.

8. Check all avionics systems for interference from the

installation.

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

pilot.

10. Update aircraft records, complete Form 337 and obtain

FAA field approval for installation, as required.
