EQUIPMENT LIMITATIONS:

An approved 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. A separate flasher assembly, such as model 7145750 or 7145751 is required for each light assembly.

The Infrared light is a non-TSO function.

Certain types of installations may require additional testing.

CONTINUED AIRWORTHINESS:

The forward position light is designed with 4 Green LEDs or 5 Red LEDs. The tail position light is designed with 2 LEDs. The Infrared light is designed with 12 LEDs. The anti-collision light is designed with 36 LEDs.

If any one bank of LEDs fails, the flasher module should be checked. If module checks good, replace the lighthead. If any one LED fails, the unit must be repaired or replaced. NOTE: To reduce eye strain, use an optical filter such as dark glasses or a blue covering dome during LED inspection. Inspect the lens. Replace if there is excessive scratching, pitting, discoloration or cracking.

Note: The anti-collision light will automatically shut-off after 9-10 flashes if a failure is detected.

INSTALLATION PROCEDURES:

The following information is to assist you in installing a Whelen light system. The installation procedure described in the following text will be confined to a single light installation, but is identical for multiple light installations.

1. Choose the appropriate Model 90569( ) light assembly.

2. Using the mounting detail information on page 2, prepare the aircraft for means to secure the LED light assembly. Remove any existing mounting adapters.
