The Navigate Series® L-849I LED Runway End Identifier Light (REIL) System is a landing aid for pilots to identify the approach end of a runway. The REIL system includes two Identifier Units (Flashers) and are installed at each side of the approach end of the runway. The lights are angled to have an effective visual range in clear weather of approximately 3 miles during the day and approximately 20 miles at night. This provides pilots with adequate time to plan and execute a safe approach and landing at night or in reduced visibility conditions.
Long LED life, eliminating expensive xenon lamp replacements.
Lower power draw compared to xenon lamps.
Three brightness intensity levels for Style E with automatic current sensing.
Light weight and state-of-the-art technology provide for ease of installation.
The system Style (A, C or E) is field-configurable and can be modified as needed to meet an airport’s requirements.
