An automotive lighting device including a light source configured to emit light in a light direction, a sensor and a cover. The sensor is configured to acquire information outside the lighting device by emitting a wave in a sensor direction, the wavelength of the wave being comprised between 1 mm and 1 cm. The cover comprises a first portion located in the light direction and a second portion located in the sensor direction, the second portion including a sensor region having a refractive index and a thickness which is between 0.8 and 1.2 times an ideal thickness, the ideal thickness being equal to a natural number multiplied by the wavelength and divided by two times the refractive index.
