- Introduction
- Signaling devices installed in roads, which give instructions of go, stop, or turn to vehicles and people passing by pedestrians by flashing red, green, yellow, or green arrow lights
- Equipped with a dimming control function to protect: driver’ eyes and reduce power consumption at nighttime
(The dimming control function is recommended by the standards for LED Traffic lights by the National Police Agency)
- Reduces brightness by 50% and energy consumption by 40%–50% if operated during day and night
