Abstract

A unique light-emitting diode (LED) light bulb which can be used in conjunction with a conventional light fixture which is mounted to a vehicle. The light fixture includes a hollow lens and a base plate attached to the lens. The base plate has a conventional socket housing with one or more contacts which is electrically coupled to a power source. The LED light bulb comprises an electrical circuit board, a plurality of light-emitting diodes mounted to the circuit board, and a connection post attached to the circuit board and adapted to be connected to the socket housing of the light fixture, where the plurality of light-emitting diodes are illuminated by the power source.

Claims

1. A light fixture adapted to be mounted to a vehicle, comprising:

a. a lens;

b. a base plate mounted to said lens and having a conventional socket housing with at least one contact being adapted to connect to a power source and two opposite slits;

c. a light bulb including an electrical circuit board, a plurality of light-emitting diodes and a connection post;

d. said electrical circuit board having a top side and a bottom side;

e. said plurality of light-emitting diodes mounted on said top side of said circuit board and electrically coupled with said circuit board; and

f. said connection post having a sidewall, a distal end and a proximal end, the sidewall having two opposite protruding flanges, the proximal end attached to said bottom side of said circuit board, the distal end having at least one contact electrically coupled to said circuit board, said connection post rotatably installed within said socket housing of said base plate such that the two opposite protruding flanges respectively latch to said two opposite slits to secure said light bulb thereto and the at least one contact of the connection post abut against the at least one contact of said socket housing for providing continuity therebetween, where the plurality of light-emitting diodes are being illuminated by the power source.

2. The light fixture in accordance with claim 1 wherein said lens is generally a hollow dome shaped body.

3. A light bulb used in conjunction with a light fixture which is mounted to a vehicle, the light fixture having a lens and a base mounted to the lens, the base having a conventional socket housing with two slits and at least one contact which is electrically coupled to a power source, the light bulb comprising:

a. an electrical circuit board having a top side and a bottom side;

b. a plurality of light-emitting diodes mounted on said top side of said circuit board and electrically coupled with said circuit board; and

c. a connection post having a sidewall, a distal end and a proximal end, the sidewall having two flanges, the proximal end attached to said bottom side of said circuit board, the distal end having at least one contact electrically coupled to said circuit board the connection post being rotatable installed within the socket housing of the light fixture such that two flanges respectively latch to said two slits to secure said light bulb thereto and the at least one contact of the connection post being abutted against the at least one contact of the socket housing of the light fixture for providing continuity therebetween, where the plurality of light-emitting diodes are being illuminated by the power source.
