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