Abstract: A vehicle side light that can decrease the number of components to reduce the cost, that does not produce a dark portion not easily visible, and that can more easily perform efficient light distribution control only in necessary directions with a simple configuration. In a vehicle side light (10) that is provided on a vehicle side surface, and that is constructed by supporting, in a light body (11), a light source (20) and a lens (30) for distributing light from the light source (20), the light source (20) is constructed by mounting a plurality of LEDs (22) on a surface of a single substrate (21), and the lens (30) is arranged in a front direction of the light source (20), and is capable of distributing light of any of the plurality of LEDs (22) to both sides of the vehicle side surface in addition to the front direction perpendicular to the vehicle side surface.

Abstract: Purpose is to enable communication with a vehicle installation installed in a vehicle in a manner that facilitates implementation of a security measure and with high sensitivity and at low cost. An in-vehicle communication system includes an interior light with communication function, a seat and a display device, the interior light with communication function including a LED configured to transmit information to the seat and the display device via visible light communication, and the seat and the display device including light receiving units configured to receive information transmitted from the interior light with communication function and control units configured to control themselves based on the information received by the light receiving units.
