Portable traffic signal light

Abstract

This product is a portable LED traffic signal light used at road construction sites and similar locations. It is a single-lamp type with multiple surface-mount red and blue LEDs arranged alternately on the same circuit board, forming separate electrical circuits for each color. Power is supplied to the device via a power cord (not shown) extending from the outside of the casing, connected to a mobile battery. A two-contact switch with a center point located on the power cord allows switching between the red circuit, complete OFF, and the blue circuit, enabling the display to be switched between red LED on, off, and blue LED on. This product is stored and used within a compartment located on the back of the front panel of a special vest worn by traffic controllers at road construction sites and similar locations.
