A wait staff signaling apparatus and method used to summon wait staff to a restaurant table includes a housing having a plurality of signaling indicators wherein the indicators illuminate by means of a light source driven by a battery and an integral control module when activated by a patron at the table by pressing or touching the respective switch. The indicators are color coded with the color codes corresponding to the type of service required by the patron. The device incorporates a high efficiency secondary optics lens component so as to provide high visibility in all light conditions at a wide variety of viewing angles, including a narrow low angle intense beam for distant viewing, thereby providing a low power, portable, battery driven device with a long service life and a low manufacturing cost. |
