Abstract

A turn signal indicator lamp system for a car including a car speed detection unit, a luminous intensity calculation unit for calculating a luminous intensity around the turn signal indicator lamp on the basis of the car speed detected by the car speed detection unit, a luminous intensity control unit for controlling automatically an irradiated angle of the turn signal indicator lamp. The operation of the turn signal indicator lamp and the irradiated luminous intensity of the turn signal indicator lamp, which are blinked with operation of the hazard warning, are controlled automatically by the luminous intensity calculation unit. The system is also applied to a brake light system and a headlight system for a car.
