An indication light in which side luminance is enhanced by disposing a diffusion member, arranged radially around an axis perpendicular to the fixing face of the indication light with a plurality of light guide bodies each having a focusing inclined face for focusing a part of light emitted from an LED light source and a reflecting inclined face for introducing the focused light to the side of the diffusion member, on the front side of the LED light source and diffusing light from the LED light source incident on each light guide body laterally. Since the side luminance of the indication light is enhanced through diffusion effect of the diffusion member, an indication light having a wide viewing field and good visibility is realized at low cost without increasing the number of LED light sources.
