Abstract
A hand-held beacon uniquely suited for hailing taxicabs is an excellent signaling device that is easy to operate and adaptable for carrying. Pushing a button on the handle portion closes a circuit to cause a light source at the top of the handle portion to beam light. In some embodiments, a reflective, blocking layer adhesively attached to the inside of the device focuses the light in a desired direction. Also desirably, the device has a plurality of annular bands. The reflective layer, which reflects light coming from outside in some embodiments is reflective also on the inside for enhanced distribution of light through the light element.
