LED bulbs for traffic lights designed by traffic light construction professionals

What are LED bulbs for traffic lights?

  • ・LED bulbs for traffic lights have sophisticated functions that have been patented.
  • ・Since they can be installed wherever incandescent bulbs are used, existing traffic lights can easily be converted to the LED type.
  • ・They consume less power than incandescent bulbs and have a longer life.
  • ・Electricity costs are reduced and since there is no need to replace the bulbs every year, the running costs are also reduced.
