This chapter gives instructions relating to maintenance of lighting equipment used on the aircraft.
1. Description and Operation
All switches are back lit rocker type. Electrical switches, the pitot heat (if installed) switch, and radio
master switches, along with other avionics switches, are located in the center instrument panel just
below the radio stack.
Flight instruments are lit by post lights. All radios and navigation instruments are lit internally.
The switch lights, instrument post lights and radio lighting are controlled by individual electronic dimmer
control assemblies operated by adjustable potentiometers. The dimmer control assemblies are mounted
on the aft side of the firewall to the right. The adjustable potentiometers are located on the lower left
instrument panel below the pilot’s control wheel.
The annunciator panel, located on the top right of the pilot’s instrument panel, includes starter engage,
alternator inop, oil pressure, vacuum inop, low bus voltage and optional pitot heat off/inop and/or carb
ice. A press-to-test switch is located to the right and a day-night toggle switch is located to the left of the
annunciator panel.
A combined instrument panel flood/map light is located above the pilot seats and is controlled by an
adjustable potentiometer type control. A dome light controlled by its own ON-OFF switch is located in the
overhead panel between the front and rear seats.
In addition to navigation lights, standard exterior lighting includes white strobe type anti-collision lights
installed in each wing tip. The Warrior III also has a landing/taxi light installed in the nose below the
propeller.
Optional exterior lighting includes wing tip recognition lights and/or a fin tip strobe.
