The Whelen 01-0771259-01 is a 28V LED taxi/landing recognition light assembly designed for aircraft exterior lighting systems. It is part of Whelen’s 71259 series, which uses compact internal LED modules combined with optical lenses to provide controlled beam patterns for taxi and runway ground operations.

This model is commonly used as a 30-degree optic taxi light configuration, producing a wide forward beam that improves visibility during ground maneuvering while reducing power consumption compared to traditional halogen PAR-36 systems.

Its primary features include:
28V DC LED taxi/landing recognition light assembly
30-degree wide beam optic for ground visibility
Designed for aircraft taxi and low-speed operations
Low power draw (~1.25A typical operation) 
Clear polycarbonate lens construction for durability 
Compact sealed LED design for vibration resistance
Direct replacement for legacy taxi/landing lighting units
Compatible with general aviation aircraft lighting systems

The Whelen 71259 series is widely used in aviation upgrades because it replaces older incandescent taxi lights with a lighter, more efficient LED system while maintaining similar mounting footprints and improving reliability in harsh operational environments.
