PASSENGER COMPARTMENT
1. DESCRIPTION AND OPERATION
This section covers the passenger compartment lighting. Each passenger light is controlled by an over-
head switch. The eyeball lights consist of two lights and switches mounted in the headliner above the
seats. Each light is round, and flush mounted with a swivel lens. Each light is individually switched with a
push on/off toggle switch. The eyeball lights are powered from the Main Bus 2 through the 3-amp Cabin
Lights circuit breaker, and receive power to the switches when the BAT 1 Switch is on.
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.
