A. Position Lights (if OÄM 42-222 is NOT installed)
The DA 42 NG has left and right position lights. The front part of each light unit has a red (left) lens
or green (right) lens. The light can only be seen from the front or the side of the airplane.
Each light unit also has an aft light. Each aft light has a clear lens. The light can only be seen from
the rear of the airplane.
A switch on the top left of the instrument panel controls the position lights and a circuit breaker
protects the system.
B. Strobe Light (Anti-Collision Light - ACL), if OÄM 42-222 is NOT installed
The middle part of each wing tip light unit has a clear optic lens for a strobe light. The filament gives
a high intensity flash. This is followed immediately by a less bright flash. The double-flashes occur
about 50 times per minute. The strobe lights can be seen from all round the airplane.
A separate power unit for each strobe light is mounted in the wing tip. A switch on the top left of the
instrument panel controls both the strobe lights and the system is protected by a circuit breaker.
The power unit generates an electrical impulse of approximately 600 Volts. The pulse ionizes the
gas in the strobe light which causes a bright flash. A second less powerful pulse occurs
immediately after the main pulse to give the lower intensity second flash.
C. LED Position and Anti-Collision Light (if OÄM 42-222 is installed)
The DA 42 NG has left and right LED position and anti-collision light assemblies. The position and
anti-collision lights are installed on a base plate covered by a clear lens. The LEDs provide the
coloration. The forward position light is covered with red (left) or green (right) LEDs. The rear
position light is designed with two white LEDs. The anti-collision light is designed with 24 white
LEDs. If one of the LEDs fails, the unit must be replaced.
The position lights and the anti-collision lights are controlled by separate switches and are
protected by individual circuit breakers.
