Description:This is the device which is often seen along highways to call attention to a barricade in the road. It is a bit more complicated than a simple RC circuit, but does use an RC time constant to control the rate at which the lamp flashes. All of the circuit components are embedded in a block of waterproof plastic, which can make them hard to see in class.
