BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention generally relates to the field of vehicle 
accessories. More particularly, the present invention relates to the field 
of light bulbs for light fixtures, e.g., turn signal lights, marker lights 
and etc., for vehicles. 
2. Description of the Prior Art 
In the prior art, most vehicle light fixtures are comprised of a hollow 
dome shaped lens, a base attached to a bottom of the dome lens, a 
connection socket housing attached to the base, and a conventional light 
bulb connected to the connection socket. The disadvantage with the prior 
art light bulb is that it is made only for one electric light bulb or 
incandescent lamp which is a tungsten filament enclosed within an 
evacuated glass bulb glows as electric current passes through it. 
It is desirable to provide a light bulb that has a plurality of 
light-emitting diodes (LEDs) which can be illuminated all at once. It is 
also desirable to provide an LED light bulb which has a conventional 
connection post for connecting to a conventional socket housing of a light 
fixture, thereby providing a conventional connection therebetween. 
SUMMARY OF THE INVENTION 
The present invention is 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 
connection socket housing with one or more contacts which is electrically 
coupled to a power source. 
The present invention 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 connection socket housing of the light fixture, where the plurality 
of light-emitting diodes are illuminated by the power source. 
It is therefore an object of the present invention to provide an LED light 
bulb with a conventional connection post which is adapted to a 
conventional connection socket housing provided by a conventional light 
fixture. 
It is an additional object of the present invention to provide an LED light 
bulb with a plurality of light-emitting diodes which can be illuminated by 
a conventional light fixture through a power source. 
It is a further object of the present invention to provide an LED light 
bulb with one or more contacts which match the contacts provided in a 
conventional connection socket housing. 
Further novel features and other objects of the present invention will 
become apparent from the following detailed description, discussion and 
the appended claims, taken in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
Although specific embodiments of the present invention will now be 
described with reference to the drawings, it should be understood that 
such embodiments are by way of example only and merely illustrative of but 
a small number of the many possible specific embodiments which can 
represent applications of the principles of the present invention. Various 
changes and modifications obvious to one skilled in the art to which the 
present invention pertains are deemed to be within the spirit, scope and 
contemplation of the present invention as further defined in the appended 
claims. 
Referring to FIGS. 1 and 2, there is shown a light fixture 2 adapted to be 
mounted to a vehicle (not shown). The light fixture 2 is conventional in 
the art and the description thereof will only be described in general 
terms. The light fixture 2 includes a generally hollow dome shaped lens 4, 
a circular base plate 6 mounted to a bottom edge 8 of the hollow lens 4 by 
conventional means, and the present invention light-emitting diode (LED) 
light bulb 10 enclosed within the hollow lens 4 by the base plate 6. The 
circular base plate 6 has a central aperture for receiving a conventional 
connection socket housing 3. The socket housing 3 is permanently fixed 
thereto by conventional means. One or more contacts 5 (only one is shown) 
are installed within the socket housing 3 and are adapted to be connected 
to a power source (not shown) by electrical wires 7. The socket housing 3 
has two opposite lateral L-shaped retaining slits 9 thereto. 
It will be appreciated that the hollow dome shaped lens 4 may be any shape, 
size or color. 
Referring to FIGS. 3 and 4, the present invention LED light bulb 10 
comprises an electrical circuit board 12, a plurality of light-emitting 
diodes 18, and a conventional connection post or means 20. The circuit 
board 12 is generally a circular shaped plate which has a top side 14 and 
a bottom side 16. The circuit board 12 is conventional constructed and 
prepared to receive electronic components, and the process for 
constructing and preparing the circuit board 12 thereof will not be 
described, since the process is well know to one skilled in the art. 
The plurality of light-emitting diodes 18 are mounted on the top side 14 of 
the circuit board 12 and electrically coupled with the circuit board 12 by 
conventional means, where the plurality of light-emitting diodes 18 are 
arranged in a circular configuration. The plurality of light-emitting 
diodes 18 may be multiple of color LEDs. The connection post 20 has an 
open proximal end 22 and a closed distal end 24. The open proximal end 22 
is attached to the bottom side 16 of the circuit board 12 by soldering 
means or any suitable means. The closed distal end 24 has two contacts 26 
which are electrically coupled to the circuit board 12 by conventional 
means 15, for example electrical wires. The distal end 24 is adapted to be 
inserted into the connection socket housing 3 of the base plate 6 such 
that the two contacts 26 of the connection post 20 abut against the two 
contacts 5 of the connection socket housing 3 for providing electrical 
continuity therebetween (see FIG. 3), where the plurality of 
light-emitting diodes 18 are being illuminated by the power source. 
The connection post 20 further includes two opposite side flanges 28 (only 
one is shown in FIG. 4) which are integrally attached to an exterior 
sidewall of the connection post 20, where the connection post 20 is 
rotatable such that the two opposite flanges 28 latch to the two opposite 
slits 9 provided on the connection socket housing 3 respectively. 
One of the unique features of the present invention LED light bulb 10 is 
that it can replace a conventional light bulb used with the light fixture 
2, without any modification to the light fixture 2 (see FIG. 1). 
Referring to FIG. 5, there is shown an alternative embodiment of the 
present invention LED light bulb 110. In this embodiment, there is only 
one contact 126 instead of two contacts 26 as previously shown. Since, the 
alternative embodiment functions the same as previously described above, 
the description thereof will not be repeated.
