Explanation
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
Operate
| 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 |
