The Whelen 01-0771424-15 is a PAR-36 LED taxi light designed as a 14V drop-in replacement for legacy incandescent sealed-beam lamps used in general aviation aircraft. It belongs to Whelen’s Parmetheus Plus series, which modernizes traditional landing and taxi lighting systems with high-efficiency LED technology while maintaining the same PAR-36 form factor.

This model is specifically optimized for taxi lighting, producing a wide beam pattern to improve ground visibility during taxi, ramp operations, and low-speed maneuvering. It replaces older halogen bulbs such as GE 4509-type lamps without requiring modifications to the aircraft lighting housing.

Its primary features include:
14V DC LED aircraft taxi light
PAR-36 form factor (drop-in replacement for sealed-beam lamps)
Wide beam optic designed for ground maneuvering visibility
Lower power consumption compared to halogen equivalents
FAA-PMA certified aviation lighting component
Vibration-resistant, sealed LED construction
Compatible with pulse/wig-wag light systems
Direct replacement for legacy PAR-36 taxi lamps

This type of LED landing/taxi light is widely used in general aviation because it significantly improves visibility and reliability while reducing maintenance needs and electrical load compared to traditional incandescent PAR-36 lamps.
