     SUMMARY OF THE INVENTION 
     The present invention includes versatile LEDs for use in a variety of applications. The present invention includes Multi Angle Functioning Led Bulbs and Lamps. 
     “Single bright” as used herein means LED lamps which typically shine at a single brightness when on, while “double bright” refers to LED lamps (such as those described in my prior patents) which shine at two different brightnesses when on (such as an LED lamp functioning as a tail light and a brake light). 
     PCB refers to printed circuit board. LED or Led refers to light-emitting diode. 
     The bulbs of the present invention can be used in the applications mentioned in my prior patents and patent applications.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     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. 
     1 Multi-Directional LED Bulbs and Lamps 
     LED bulbs and lamps with LEDs pointing to the sides, top, bottom, and even to the back in addition to the front are desirable to light up more or different parts of the lamp and or lens or to produce more total light in many applications. Various viewing angles and configurations are used to achieve the desired light pattern and brightness. If the correct viewing angle and number of LEDs are selected and placed at the proper locations, it is possible to emit light at the same or near same viewing angle of the incandescent bulb for that application. Restrictions and customizations are achieved by changing the variables of PCBs, LEDs and positioning during the manufacturing process. One group of examples are lollipop LED bulbs with one or more PCBs where LEDs face opposite directions in various or same colors that replace incandescent bulbs in fender top mounted turn signal and running lights on freight trucks. Typically they have amber lenses on front and red on rear facing, but it is also common for red and red. The LED colors, types, brightness, viewing angles and so forth as well as positioning are preferably all determined for specific applications. A second group of examples are single or multi directional LED bulbs for cab top lights in trucks. Another example is one or more PCB radial LED bulbs used for tail lights, running lights, marker lights, and much more where light is directed both directly to lens and also directed to reflector or housing. The embodiments are virtually limitless but examples are shown using 1 PCB, 2 PCBs, 3 PCBs, 4 PCBs and 5 PCB in a variety of arrangements, using various circuitries, positioning and configurations each for use in specific or universal applications. Applications are encompassing. Examples of some applications are flashlights, trucks, trailers, motor cycles, automobiles, marine, aviation, commercial, industrial, agricultural, government, rail, and home. These bulbs are different from prior art known to the inventor (LEDtronics bulbs) because prior art bulbs are limited to 2 stacked PCBs with LEDs on one side of one PCB pointing one way, and LEDs on one side of a second PCB, pointing out radially from the center, toward the sides. Six LEDs are each spaced 60 degrees apart in a circle, lying on their sides. The two PCBs are attached using “stanchions”, preferably three, to attach the two PCB&#39;s together. In contrast, the bulbs of the present invention use no stanchions to attach only 2 PCBs together nor do the LEDs necessarily mount upright on the top of a top PCB and down flat on a second PCB in a radial configuration nor are they limited to two PCBs. All bulbs of the present invention either operate in single brightness mode, dual brightness mode, or combination, or with split LEDs (as in the prior art to U.S. Pat. No. 6,371,636) or shared single brightness LEDs (for example, brake/tail LED bulbs in which some LEDs light up for tail and all light up for brake) or integrated dual element operation (as in U.S. Pat. No. 6,371,636) if dual action.
