The new traffic lights you are seeing are made out of arrays of mild emitting diodes (LEDs). These are tiny, purely digital lights which might be extremely power environment friendly and have a very long life. Each LED is about the size of a pencil eraser, so a whole bunch of them are used together in an array.

A giant city has thousands of intersections, so it could cost millions of dollars simply to energy all of the traffic lights. LED bulbs would possibly consume 15 or 20 watts instead of 100, so the ability consumption drops by a factor of 5 or 6. A metropolis can simply save one million dollars a yr by replacing all of the bulbs with LED items. These low-energy bulbs also open the possibility of utilizing solar panels instead of operating an electrical line, which saves money in remote areas. What are amps, watts, volts and ohms?
