A hand held beacon uniquely suited for hailing taxicabs is an excellent signalling device that is easy to operate and adaptable for carrying. By pushing a button on the handle portion that releases a protruding member from a groove in a light element, the tubular plastic light element that has a lower annular metal lip and that is telescoped between an outer tube and an inner copper tube springs up and closes a circuit to cause a bulb at the top of the handle portion to beam light through the light element.
