TUBE FLASH (P/N r4321a) - New Surplus

The r4321a is a xenon gas-discharge tube flash element for aircraft anticollision strobe lighting systems. This lamp provides the bright light source within exterior beacon and strobe assemblies used for aircraft visibility during low-light conditions and night operations. Commonly found in Hawker Beechcraft anticollision systems, the tube flash restores strobe output when the original lamp dims or fails.

Installation requires following the aircraft maintenance manual and wiring schematics specific to your airframe. Verify the correct part number in the Illustrated Parts Catalog before replacement to ensure compatibility with your strobe assembly.
