Passenger compartment courtesy light

The courtesy light with passenger compartment lighting controls (reading light) F35 is supplied directly by the battery, routed through fuse F16 (7.5A) of the fusebox G1; this permits the reading light or courtesy light to be illuminated by acting on the relevant switch.

When the sidelights are on, F35 receives another supply which lights up the ideograms on the controls.

The passenger compartment courtesy light F3 also receives supply direct from the battery and once again is routed through fuse F16 (7.5A).

Timer controlled courtesy light:

The courtesy light electronic timer device N10 controls illumination of the courtesy lights F35 and F3 and of the lamp illuminating the ignition switch ; where applicable

Battery voltage is supplied through fuse F16 (7.5A) in the fusebox G1 to the Ta and Tb devices of N10. Pin 11 of the device receives the "door open" signal from the Check Panel C16 when any door is opened (this signal is the same as that which prevents locking/unlocking of the doors - see "Door locking system").

The Ta timer sends a ground signal through pins 8 and 9, to the timer controlled lamps , and F16 (supplied by battery voltage by the fuse line ) and illuminates them for 100 to 200 seconds from the moment the door is opened. When the "door open" signal is interrupted, the Tb timer sends the same negative signal and illuminates the lights for a further 10-20 seconds approximately.

From chassis N.___, the timer has been modified: the key operated power supply signal which interrupts the timing when the ignition key is engaged reaches pin 2.

Luggage compartment lighting:

The luggage compartment courtesy light F5 is also illuminated by battery voltage routed through the line protected by fuse F16 (7.5A); it comes on when the boot lid is opened and switch H24 sends a ground signal

From chassis N.2521 a radio anti-interference condenser N53 is installed to prevent disturbances from the roof light .
