The calculated value Vn calculated by the vehicle speed calculation means 5 is input to the light intensity control means 6 in the central control unit (CPU) 11. The light intensity control means 6 also includes the above-mentioned manual operation switch SW1 and door switch SWo ON/OFF.
When the manual operation switch SW8 is turned on manually, or when the movable terminal d of the manual operation switch SW8 is set to the contact C on the door switch side, and the door switch SWD operates only in at least two cases when there is an input in the ON state, and compares the input vehicle speed value Vn with a predetermined set value Vs (for example, Vs = 40 Km/h),
When the calculated actual vehicle speed value Vn is equal to or higher than the set value Vs, a dimming signal is output to the control current output circuit 7 to determine the value of the control current i to be output to the switching transistor Q. By reducing the value of the electric current flowing through the room lamp 1, the luminous intensity of the light emitted by the room lamp 1 is reduced.
