EXTERIOR LIGHTING
1. DESCRIPTION
This section contains information on servicing the landing, position, and integral anti-collision strobe lights.
The anti-collision light assembly and strobe light power supply are mounted to the outboard surface of
each wing tip. The light assembly includes a strobe light with forward (red-left, green-right) and white posi-
tion lights.
A single 34-watt High Intensity Discharge (HID) landing light is installed in the lower left engine cowling.
The light is spring-mounted to the engine cowl and is ground adjustable by mounting screws. The landing
light is powered from a ballast mounted on the firewall. The ballast provides increased voltage to illuminate
the HID lamp. Electrical power is supplied directly from the main distribution bus and a 15-amp fuse in the
MCU.
WARNING:
Always disconnect the power supply prior to servicing any portion of the electrical
system. Ensure the main power switch is in the off position; then remove the negative
battery cable first and then the positive battery cable.
CAUTION: Always wear clean cotton gloves when working with light bulbs. Never allow the glass por-
tion of the light bulb to come into contact with exposed skin. Oils from the exposed skin will
cause premature bulb failure.
