Dome lights. The dome lights are installed in the crew compartment for interior illumination. The dome light switches
provide for either white or colored light as the tactical situation requires.
4.
High beam indicator light. A high beam indicator light glows red when the vehicle service drive headlights or IR
headlights are changed to high beam through the driver's dimmer switch.
5.
Winch compartment light. The winch compartment light is operated by a switch on the accessories panel and illumi-
nates the hoist winch, main winch, and surrounding areas in the winch compartment.
6.
Rigger's fixed spotlight. The rigger's fixed spotlight is controlled by a handle that extends through the roof into the
rigger's area in the crew compartment.
7.
Rigger's service light assembly. The rigger's service light assembly, controlled by the rigger's light selector switch,
projects a high beam.
8.
Rigger's B.O. light. The rigger's B.O. light is controlled by the rigger's light selector switch and projects a high beam.
