Abstract
Disclosed is a lighting device (D′) on a motor vehicle, including: at least one light source (D1, D2, D3, D4) controlled by a pulse-width modulated lighting signal (PWM′); and a body controller module (10) generating the lighting signal (PWM′) linked to the light source and, to at least one sensor (100, 200, 300, 400) detecting the approach and/or contact of the user's hand. The device includes a switching element (S1, S2, S3, S4) located between the detection sensor and the light source. The detection sensor includes: receiving and a processing element (101, 201, 301, 401) of the lighting signal; and a control element (102, 202, 302, 402) of the switching element, linked electrically firstly to the receiving and processing element, and secondly to the light source via the switching element. Also disclosed is a method for controlling the light source.
