Abstract
A vehicular room illuminating lamp includes: a plurality of illumination units applying voltages through courtesy wires thereof to lamps which irradiate positions in a vehicle cabin, the positions corresponding to four doors; a mode switch capable of selecting an all-lights-on mode, a door mode and a light-off mode; and a controller that individually receives a mode selection signal of the mode switch and respective door open/close signals of the four doors. The controller applies the voltages to all of the courtesy wires in the all-lights-on mode, applies the voltage only to the courtesy wire of the illumination unit corresponding to the door indicated to be open by the door open/close signal in the door mode, and does not apply the voltage to any of the courtesy wires irrespective of states of the door open/close signals in the light-off mode.
