Abstract: A beacon light includes a tubular bottom shell having a closed end and an open end. A battery housing is in the bottom shell and is adapted to contain batteries and connect them in series. A tubular, translucent light diffuser is on and secured to the open end of the bottom shell. A printed circuit board is in the light diffuser. A plurality of light emitting diodes (LEDs) are mounted on the printed circuit board and electrically connected in parallel with respect to each other. Also on the printed circuit board is a switch and a integrated circuit which are electrically connect in series with the LEDs. The printed circuit board also has battery contacts at one end which engage electrodes on the batteries in the bottom shell so as to connect the LEDs to the batteries through the switch and the integrated circuit. A switch button extends through the light diffuser and is adapted to engage the switch to operate the switch. A cap is on the top of the light diffuser.
