** ON A/C NOT FOR ALL For ZODIAC Runway Turnoff Lights the runway turnoff-light system consists of:
- Two single-filament lamps (or halogen lamps in alternate solution)(3LC1, 3LC2), installed in a fixed position on the nose landing gear. Each lamp is rated at 150 Watts,
- One transformer, that gives the rated operating voltage,
- One relay of the runway turnoff-light power-supply (6LC), and
- One switch of the runway turnoff external-light (2LC), installed in the cockpit on the overhead panel.

4. Operation
The 115 VAC busbars 204XP and 103XP supply power to the runway turnoff-light system, through circuit breakers 1LC1 and 1LC2. A switch 2LC controls the control circuit, it gets power from the 28 VDC busbar 202PP through circuit breaker 2LR. A ground signal for the power control relay 6LC is available from the landing gear computer.
The ground signal is connected, when the nose landing gear is locked down. The power control relay 6LC and the control switch 2LC get power when the busbars are energized and the circuit breakers are closed. The runway turnoff lights come on when the switch 2LC is in the RWY TURN OFF position. When the nose landing gear is unlocked, the ground signal for the power control relay is disconnected. The runway turnoff lights 3LC1 and 3LC2 go off.
