This is to prevent against car accidents in advance by giving visual warnings to drivers and pedestrians using Alarm Device (using a signal lamp) on the roads of residential areas, business areas, School zones, local housing areas, back roads and non-signal based intersections
An environmentally-friendly system using solar energy (commercial electrical power system also available)
An active and intelligent safety facility to detect vehicles with built-in optical sensors within the signal lamps and to warn about the approach of vehicles to drivers and pedestrians

Conceptual Diagram

Operation Principle(Installation Overview)

  • This is done by installing a signal lamp including an LED and sensors to detect the vehicles (the optical sensor detects the vehicle’s headlights) at the center of the intersection, supplying the power is supplied using a solar cell (Commercial electrical power is also available)
  • It gives a warning sign to the approaching cars or pedestrians by blinking the LED, if the entry of cars is detected


Daytime The Yellow LED blinks all the time
Night time It detects vehicles using the optical sensors in the signal lamp.
If there are no vehicles The LED blinks Red (Vehicle direction, 2 times/sec)
If there is an Approaching vehicle Both of the Yellow and the Red LED blinks
  The Red LED will be blink on toward an approaching car (Blinking speed will be faster)
  The Yellow LED will be blink on toward pedestrian
