My name is German Osorio Cortes from Buga-Colombia. I have an idea to change the old traffic light system. We don't need 3 lamps (Red, Yellow and Green) for the traffic lights. We only need 1 LED lamp with dual color LEDS (Red and Green).
1) Green LEDs on: run
2) Green and Red LEDs = Yellow: prevention.
3) Red LEDs on: Stop.
My system is very easy and inexpensive and work for two hours when the electricity fails.
