ABSTRACT:
A side directional signal includes a base and a cover that together define a compartment receiving a circuit board on which first and second groups of light-emitting diodes (LEDs) are mounted. Mounted between the LEDs and the cover is a light-guiding plate including an inner face with a plurality of semispheres aligned with the LEDs. The light-guiding plate further includes an outer face with grooves. A portion of the semispheres concentrates the light beams emitted from the first group of LEDs to provide enhanced brightness. The concentrated light beams transmit through the outer face and then the cover after being reflected by sidewalls of the grooves. A reflective plate is mounted between the first and second groups of LEDs. The light beams emitted from the second group of LEDs are concentrated by a remaining portion of the semispheres, reflected by the reflective plate, and transmitted through the cover.
