• each lens body includes a front light exiting surface and a rear surface that includes a light incident surface on which light emitted from the LED light source is incident,
• each light incident surface is a cylindrically recessed light incident surface that is formed by extending a concave semicircle section with respect to the LED light source in a direction to define a recessed space, and each LED light source is disposed within the recessed space defined by the light incident surface so that the light emitted from the LED light source is incident on the light incident surface, and
• the second optical module and the third optical module are disposed on respective sides of the first optical module.
