This section provides an introduction to the ADB Safegate FAA Type L-849V (voltage) and I (current), Style A and E, REIL with
LED optical flash heads. (See Figure 1 .) The ADB Safegate FAA Type L-849V (voltage) and I (current), Style A and E, REIL with
LED optical flash heads consists of two unidirectional light units, one located on each side of the runway. Each REIL assembly
utilizes an integrated head and power supply. The Primary REIL assembly controls operation of the Secondary REIL assembly.
Remote control signals are connected only to the Primary assembly. These light units flash twice a second to provide a visual
indication to pilots of the runway threshold during an approach for landing.
