Abstract:
An LED light bulb adapted for use in standard automotive bayonet type bulb sockets in a brake light mode and a tail light mode, comprising:a printed circuit board; a plurality of light emitting diodes mounted on the printed circuit board and electrically coupled with the printed circuit board; a body having a first end and a second end, with the printed circuit card attached to the first end of the body; a base having a sidewall, a distal end and a proximal end, the sidewall having two alignment pins thereon, the distal end having at least one contact; and electrical control means electrically connected between first and second contacts on the base and the printed circuit board, whereby when an electrical signal is supplied to the contacts the electrical control means transmits a processed electrical current enabling the light emitting diodes to be energized and emit light, wherein the electrical control means causes substantially all light emitting diodes to illuminate when used in either the tail lamp mode or the brake lamp mode, and causes the intensity of the individual light emitting diodes to be greater when in brake lamp mode than when in tail lamp mode.
