to control the flows of traffic at road intersections,
pedestrian crossings and other locations
Solar traffic lights are signalling devices powered by solar panels positioned at road intersections,
pedestrian crossings and other locations to control the flows of traffic.
They assign the right of way to road users by the use of lights in standard colors (red - amber/yellow - green),
using a universal color code (and a precise sequence to enable comprehension by those who are color blind).
Most of the solar traffic lights have battery back-up for functioning during night.
solar traffic lights use LED lamps as they are more reliable and have more advantages over other lighting devices
like CFL lamps as they are more energy efficient, have a longer life span and turn on and turn off quickly.
