The traffic light shows lack of Duality of patterning and productivity It shows lack of duality of patterning because it has only discrete meaningful segments that each light red, orange, green are contain meaning (Stop/Prepare to stop/Go) but if we want to apply a principle of traffic light to create a lot of communication we have to add more lights equal to the number of orders that we want to convey such as pink light means open car window or blue light to driving at speeds lower than normal. If so, it very complicated to a sender and receiver because if we need 30 orders we have produced different 30 lights to convey 30 orders and is not easy in terms of creating lights that have 30 different colors, and the difficulty in interpreting and remembering the color of the light. Also, the traffic light shows lack of productivity that traffic light can only convey meaning about the car can go or stop.
