The traffic light has several different names, like traffic signal, stop light, traffic lamp, stop-and-go lights, robot or semaphore.Its is used to indicate, using a three colours Red Yellow and Green. The traffic lights we know mean Red is stop, Green is go and Yellow is “prepare to stop”, but in the UK, Canada and New Zealand, Yellow means stop aswell. Also in the UK, Hong Kong, Macau, Pakistan, Germany, Hungary, Czech Republic, Poland, Denmark, Iceland and Israel, red and yellow light up together to mean “prepare to go”.

Old Traffic lights looked like a clock with one part of a circle red, one yellow and one green and the arrow in the middle would indicate by pointing to the colour these were called Marshalites. But in the 1990’s a more cost effective lamp was made, it was run by electicity and consisted of lights the lighted up to indicate. These are called LED lights (Sorry, forgot to say that last bit in Audio :oops:)
