Abstract

To provide a lighting system capable of suppressing dazzling sensation felt by passengers while ensuring eye-catching quality.SOLUTION: A lighting system 100 includes: a door illumination 1L (1R) provided on an inner surface of a side door; a rear detection sensor 43L (43R) for detecting an object around a vehicle; and a control device 3 for controlling the door illumination 1L (1R) based on a detection result of the rear detection sensor 43L (43R). The lighting system 100 further includes a brightness sensor 45 for detecting brightness around the vehicle. The control device 3 is configured to turn on or blink the door illumination 1L (1R) when the object is detected by the rear detection sensor 43L (43R), and is configured to adjust the brightness when turning on or blinking the door illumination 1L (1R) according to brightness detected by the brightness sensor 45.SELECTED DRAWING: Figure 1
