Each optic is covered by a respective lens cap. A single LED is connected to the body in alignment with the center optic. The center optic receives light emitted by the LED and divides the light such that a first portion thereof is emitted from the light bar through the center lens cap, a second portion thereof is transmitted along the left light pipe and emitted through the left lens cap, and a third portion thereof is transmitted along the right light pipe and emitted through the right lens cap.
