WL77 + L.I.L Bracket | Aircraft Warning Lights

WL77 Single Aviation Obstruction Light
Engineered for reliability, the WL77 is ideal for marking telecom and GSM towers, cranes, hoists, chimneys, buildings, and other structures that may pose a hazard to air navigation.

Its die-cast aluminum body, finished in a durable black or yellow powder coating and mounted on a sturdy LIL bracket, offers a lightweight yet robust construction that is waterproof, shockproof, and corrosion-resistant. The base cable entry simplifies installation and servicing, while the long-life external LEDs provide consistent visibility and extended operational lifespan.

This obstruction light combines precision optics and modern LED technology for exceptional performance. The Fresnel lens ensures even light distribution within the required beam angle, while energy-efficient LEDs deliver high brightness with minimal power use.

The durable polycarbonate housing offers excellent impact resistance, thermal stability, and high light transmittance. Its die-cast aluminum base, finished in yellow or optional red powder coating, provides superior corrosion protection.

Designed for convenience, it features an optional built-in photocell for automatic day/night operation, a secure stainless steel safety wire, and compatibility with a G3/4” mounting pipe. Available in steady or flashing modes without the need for an external controller.
