The irradiation pattern (Pi) has a main instruction symbol (Am) and one or more sub instruction symbols (Av), and the main instruction symbol (Am) is emphasized more than the sub instruction symbol (Av). In the projection lens (12), with an impingement surface (25) as a continuous surface, there are an upper lens part (31) that forms the main instruction symbol (Am), and a lower lens part (32) that forms the sub instruction symbol (Av). In the projection lens (12), at least both end parts in the horizontal direction of an upper emission surface (26A) that emits light from the light source (21) in the upper lens part (31) protrude further to the projecting side than both end parts in the horizontal direction of a lower emission surface (26B) that emits light from the light source (21) in the lower lens part (32).
