PROBLEM TO BE SOLVED: To enable accurate light distribution control during rainfall and snowfall.SOLUTION: A light-transmitting member 2 partitions a part of a lamp chamber 4. A light source 5a is stored in the lamp chamber 4, and irradiates light forward through the light-transmitting member 2. A detection means 6 is stored in the lamp chamber 4, and obtains information of the front through the light-transmitting member 2. A step part 7 is formed on an outer surface of the light-transmitting member 2, and guides a waterdrop stuck to the outer surface to make it avoid a detectable range of the detection means 6. |
