The Whelen 01-0770029-29 is a self-contained red anti-collision strobe light assembly designed for 14V aircraft electrical systems. It belongs to Whelen’s HRCFA / CometFlash-style beacon family, which integrates the flash tube, reflector, and control electronics into a single sealed unit, eliminating the need for an external strobe power supply.

This unit is typically installed on general aviation aircraft as a red rotating-beacon replacement or supplemental anti-collision light, mounted on the fuselage or vertical fin. It produces high-intensity xenon strobe flashes that improve aircraft visibility in both day and night operations.

Its primary features include:
14V self-contained xenon strobe anti-collision light
Red lens configuration for aviation beacon applications
Integrated flash tube, reflector, and electronics (no external power pack required)
FAA-approved aircraft lighting component (legacy HRCFA series)
Designed for direct replacement of older rotating beacons
360° visibility for improved aircraft recognition
Durable, vibration-resistant sealed construction
Commonly used on general aviation aircraft fuselage or tail mounts

This model is part of a legacy Whelen strobe system that has largely been replaced in modern installations by LED anti-collision lights, but it is still widely encountered in maintenance and retrofit work on older aircraft fleets.
