Taxiway light

for airport runwayfor airportLED

Product overview
The circular runway threshold light is designed for runway and taxiway threshold marking. The lamp body is made of aluminum alloy with anti-corrosion surface treatment and a high-strength forged cover. The LED light source is low-profile (LED protrusion 6.3 mm) to reduce impact on aircraft tires; equivalent halogen protrusion is 12 mm. The unit meets airport lighting mechanical and optical safety requirements and resists severe environmental conditions.

Technical specifications

Installation and maintenance
The unit is designed for flush installation in runway surfaces. Smooth cover geometry minimizes risk of tire damage. Fasteners and modular components allow straightforward replacement on site. Although the LED source is maintenance-free, periodic inspection of optical surfaces, seals and fasteners is recommended per airport maintenance schedules.
