PROBLEM TO BE SOLVED: To provide a signal light capable of preventing pseudo lighting by shielding sunlight from the front of the signal light and obtaining sufficient signal light luminance. SOLUTION: This signal light is composed of a light source 1, a reflector 2, a light source side lens array LA1 having a convex on the light source side, a sun side lens array LA2 disposed on the sun side while having positive refracting power, and a light shading plate 6 provided in the vicinity of the light source side focus of the sun side lens array to enhance shading of the sunlight and the light distribution of the signal light, and the optical axis of the LA2 is eccentrically shifted downward by a prescribed eccentricity relative to the axis of the LA1.
