The PRO III 8" RCLI/TDZI/REXI light is a highly adaptable, multi-function in-pavement airfield lighting fixture designed to serve as a Runway Centerline Light (RCLI), Touchdown Zone Light (TDZI), or Rapid Exit Taxiway Indicator Light (REXI). Engineered to meet the demanding needs of both civilian and military airfields, this unit delivers dependable performance across a wide range of applications. Whether used to mark the centerline of a runway, indicate the touchdown zone for aircraft landing, or guide ground traffic on rapid exit taxiways, the PRO III 8" fixture offers precise lighting with optimized beam direction and color configurations.
As a runway centerline light (RCLI), the fixture is bidirectional and commonly configured with clear/clear or clear/red optics, utilizing two 48-watt quartz halogen lamps for reliable output. In its touchdown zone (TDZI) configuration, the unit operates as a unidirectional clear light with a single 48-watt lamp, delivering critical visual guidance for aircraft approaching the runway. The rapid exit taxiway (REXI) configuration transforms the fixture into a yellow unidirectional light designed to support safe and efficient ground operations by helping aircraft vacate the runway quickly and safely, thus reducing runway occupancy time.
The PRO III 8" light complies with ICAO Annex 14 requirements and conforms to Figures 2.5, 2.6, and 2.7, making it suitable for any ICAO Category I, II, or III runway, as well as military airfields. Its low-profile design—less than 0.25 inches (6 mm) above the pavement surface—meets FAA Style 3 requirements and minimizes disruption to aircraft and ground vehicle movement. The optical assembly is constructed from high-strength aluminum for durability and weather resistance.
Designed for ease of maintenance and operational efficiency, the unit features low power consumption and a simplified structure with few parts, making inventory and servicing straightforward. The beam orientation can be quickly adjusted for left or right toe-in without complex disassembly, and there is no need for sealant when replacing the prism or feedthrough assemblies. A pressure test plug is included for verifying seal integrity, and the shallow base design ensures compatibility with installations where depth constraints exist. Overall, the PRO III 8" RCLI/TDZI/REXI light provides a versatile, low-maintenance, and ICAO-compliant lighting solution for modern airfield environments.
