Operation
The supply to luggage compartment lamp 55 is taken from fuse 28 and then on to switch 56. When the luggage compartment lid is opened, the switch will close the circuit to earth and the lamp will light up.

The luggage compartment illumination can be switched off manually by means of the switch in the lamp fitting.

Convertible
On the Saab 900 Convertible, the luggage compartment lamp is switched on and off by means of a mercury switch (56) which closes the supply circuit when the lid is opened.
