A lamp housing (143) houses a light source (141). A front sensor housing (152) houses a front LiDAR sensor (151). A supporting unit (17) supports the lamp housing (143) and the front sensor housing (152). The lamp housing (143) and the front sensor housing (152) are arranged in a direction corresponding to a left-right direction of a vehicle, when viewed from a direction corresponding to a front-rear direction of the vehicle. A maximum dimension (UD1) of the lamp housing (143) in an up-down direction of the vehicle is smaller than a maximum dimension (UD2) of the front sensor housing (152) in the same direction.
