Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a traffic light that has no entering dust between a snow accretion preventive plate and a surface of a display unit while preventing snow from accreting by tilting the snow accretion preventive plate forward, is easy to clearly see, and has a simple structure.SOLUTION: The front of a housing part 13 is brought into close contact with the back of the snow accretion preventive plate 12 which has optical transparency and is arranged tilting forward. In the housing part 13, a lighting instrument is housed through an opening bored in the front of the housing part 13 so that a display surface of an LED unit comes into close contact with the back of the snow accretion preventive plate 12. Further, the part where the front of the housing part and the back of the snow accretion preventive plate come into close contact with each other in the periphery of the opening of a circle is wider than a rectangular range circumscribed with the circle which is a size larger than the opening.
