The interior lighting systemconsists of the dome lights, passive night viewer, winch lights, gauge panel lights, fixed spotlight and troublelightassembly. The exterior lighting system consists of the headlights, stoplights, marker lights, turn signals, rear ser-vice light and warning flasher.System power (+24 -- 28 V dc) is supplied to the interior lighting system any time the MASTER switch is turnedON. The left front and left rear dome lights are supplied through a switch panel 15--amp circuit breaker while thecenter and right front dome lights, winch lights, fixed spotlight and troublelight assembly are supplied through anaccessories panel 15--amp circuit breaker. The gauge panel lights are supplied through a separate circuit from thelight switch assembly in the switch panel. Each dome light has a three position switch that allows either a whitelamp or a blue (blackout) lamp to be turned on or both lamps to be turned off. The fixed spotlight and troublelightare both turned on and off at their respective lamp locations. The winch lights are turned on and off by the WINCHLT switch on the accessories panel. The passive night viewer operates when the PASSIVE NIGHT VIEWERswitch is set to the ON position. The PASSIVE NIGHT VIEWER indicator also lights whenever the PASSIVENIGHT VIEWER switch is turned ON. The gauge panel lights are lit whenever the main lighting switch on theswitch panel is set to any position other than OFF. The gauge panel lights are then controlled by the auxiliaryswitch and can be set to either PANEL BRT (bright), DIM, or OFF. If the main light switch is set to the SER DRIVEposition and auxiliary switch is set to PARK, dim panel lights are automatically selected.System power (+24 -- 28 V dc) is supplied to the external lighting system whenever the MASTER switch is turnedON. Power is applied through a circuit breaker in the switch assembly and, depending on switch position, routed toselected lamps. The main lighting switch defines the operating mode of the external lighting system and includesSER DRIVE (service drive), STOP LIGHT, BO MARKER (blackout marker), BO DRIVE (blackout drive) and OFF.In the OFF position, all circuits are open and no lights are lit. In the SER DRIVE position, the service drive head-lights, service drive stop lights, and service drive turn signals are all operable. When the STOP LIGHT position isselected, the service drive turn signals and service drive stop lights are operable. In the BO MARKER POSITION,the blackout marker, blackout turn signals, and blackout stop lights are operable. When the BO DRIVE position isselected, the blackout driving lamp, blackout marker, blackout turn signals, and blackout stop lights are all oper-able. Additionally, in the BO DRIVE position, a BO SELECTOR switch enables blackout driving lamps.When the service drive headlights are in operation, a dimmer switch selects either a low beam headlight or a highbeam headlight. The HIGH BEAM indicator lights whenever the high beams are selected.When the brake pedal is pressed and the turn signal control lever is in the center position (no turn signal operation),both stoplights will light. If the turn signal is in the right turn position when the brake pedal is pressed, only the leftstoplight will light; and, in the left turn position only the right stoplight will light. When the turn signal control lever isin the right turn position, the right front turn signal lamp and the right rear turn signal lamp will flash. Likewise,when the turn signal control lever is in the left turn position, the left front and left rear turn signals will flash. If theturn signal control lever is pulled out, all four turn signal lamps flash. When the turn signal control lever is in eitherthe right turn, left turn, or 4--way flasher position, the indicator on the directional signal control assembly will flash tosignify turn signal operation.
