The RELIANCE Runway Edge Elevated Light (L-861(L)) is a medium-intensity, omnidirectional elevated LED light fixture engineered for marking the edges, thresholds, and ends of airport runways. Available in white, yellow, red, and green light outputs, this fixture serves a vital role in both daytime and nighttime airfield operations, providing clear, reliable visual guidance for aircraft under various operating conditions. Designed for use on visual and non-precision instrument flight rules (IFR) runways, the RELIANCE L-861(L), L-861E(L), and L-861SE(L) models are ideal for applications ranging from standard runway edge marking to threshold, end, and stopway delineation. These lights are also fully compatible with non-precision approach runways as defined by ICAO and Transport Canada.
The RELIANCE runway light series is engineered to meet or exceed multiple international and national standards. It complies with the FAA AC 150/5345-46 current edition and FAA Engineering Brief No. 67, with full ETL certification for L-861(L), L-861E(L), and L-861SE(L) designations. It also satisfies ICAO Annex 14, Volume I (current edition), Transport Canada TP 312 requirements (paragraph 5.3.12.7 and Appendix 5B Table 5B-1), and the Australian MOS Part 139 standards (sections 9.10.6, 9.10.13, 9.10.19, and 9.10.22), making it suitable for installation in airfields worldwide.
A key advantage of the RELIANCE elevated LED runway light is its long operational lifespan. Under high-intensity conditions, the LED light source averages 56,000 hours, and under typical usage, it exceeds 150,000 hours—greatly reducing maintenance demands and virtually eliminating the need for regular re-lamping. The fixture is built for durability and ease of maintenance, featuring a single-latch stainless steel clamp for quick access to the internal components. Watertight sealing is ensured by gaskets placed between the lens and top cover, as well as between the upper and lower halves of the fixture housing.
For cold climates, an optional arctic configuration includes a thermostatically controlled heater, which prevents ice and snow accumulation from obstructing the light output—offering a performance comparable to traditional incandescent systems. Installation flexibility is built in with three screws that provide a 4° leveling adjustment after mounting, ensuring proper alignment and visibility. The fixture is shipped with a standard 1.5-inch coupling but can also be ordered with a 2-inch coupling or alternative thread types to suit different mounting systems.
With its rugged construction, multi-standard compliance, and extremely low maintenance requirements, the RELIANCE L-861(L) series offers a reliable and cost-effective solution for modern airfield runway lighting systems.
