PROBLEM TO BE SOLVED: To provide cargo lamps with high heat dissipation performance that can satisfy a predetermined light distribution standard.SOLUTION: In the cargo lamps 1 having a bulb (light source) 5 housed in a light chamber 4 defined by a housing 2 and a lens 3 covering an opening portion of the housing, light emitted from the bulb 5 is reflected twice in the light chamber 4 and a heat dissipation holes 7 are formed on the upper wall and the lower wall of a position of the housing 2 where the bulb 5 is arranged. Specifically, an inner surface of the housing 2 is set as a reflecting surface so that light reflected by an inner surface 2a of the rear wall of the housing 2 is reflected by an inner surface 2b of the upper wall or an inner surface 2c of the lateral wall of the housing 2. The cargo lamps 1 are arranged on both sides of a high mount stop lamp 11 arranged at the center in the vehicle width direction of the rear portion of the vehicle. |
