Abstract
A DRL unit as a vehicle signaling light can include: an LED light source; and a plate light guiding lens formed from a light guide plate. The light guide plate includes: a light guide plate main body having a light output surface; and a light entrance portion that is formed to be continuous with the light guide plate main body and includes a light incident surface opposite to the light source and upper and lower expanded portions. The upper and lower expanded portions are integrally formed with the light entrance portion on top and bottom surfaces of the light entrance portion so as to expand in the thickness direction of the light guide plate main body. Here, the upper and lower expanded portions can have asymmetric cross sections in the thickness direction and different sizes when seen in a top plan view.
