Abstract: A lighting apparatus and method of use provides for increasing the visibility of a cyclist. The lighting apparatus includes a plurality of lights that may be arranged in a linear array to facilitate attachment to elongate members of a bicycle. The plurality of lights can be mounted on a substrate that is received in a mounting member, which in turn can be attached to a bicycle. Alternatively, the lighting apparatus may be formed integrally as part of a bicycle. Attachment of one or more lighting apparatuses to a bicycle can provide for increased visibility of a cyclist from the front, the rear, or the side, and may be configured to provide increased visibility when it is either dark or light outside.

Abstract: An LED lighting device for use in and powered through an incandescent light bulb alternating current socket is provided. The lighting device includes an LED light, a regulation circuit and a base. The regulation circuit converts an alternating current input to a direct current output. The base is adapted to fit within an incandescent light bulb alternating current socket. In addition to the LED light, regulation circuit and base, the invention can further include a heat sink that removes heat from the LED light, regulation circuit and combinations thereof. Preferably the heat sink is a ceramic. In addition, the regulation circuit can be a printed circuit that is printed directly onto the ceramic heat sink. The LED light, regulation circuit, base, and ceramic heat sink take the form of a lighting device that is exchangeable with an incandescent light bulb in traditional lighting fixtures.
