Claims

1. A resistor bypass circuit for a series lighting circuit comprising a plurality of serially connected light sources and a bypass resistor being connected in parallel with at least one of the respective light sources, each respective light source low wattage and being capable operating on a one hundred percent duty cycle as desired.

2. The resistor bypass circuit of claim 1, where the circuit is series-parallel connected.

3. The resistor bypass circuit of claim 1, the light source being an incandescent bulb.

4. The resistor bypass circuit of claim 1, the light source being a semiconductor

5. The resistor bypass circuit of claim 1, the light source being an LED.

6. The resistor bypass circuit of claim 4, the light source the semiconductor light source providing a twinkling effect.

7. The resistor bypass circuit of claim 6, the semiconductor light source utilizing electronic circuits that control the flashing rate of the light source, which would only affect the individual lighting element as the resistive bypass would allow current to continue to flow in remaining lighting elements in the series circuit.

8. The resistor bypass circuit of claim 6, the electronic circuits being LED packages that incorporate integrated circuits (ICs)

9. The resistor bypass circuit of claim 5, the light source being a semiconductor light source for providing color changing characteristics.

12. The resistor bypass circuit of claim 11, the control only affecting individual lighting element, the bypass resistor providing for current continuing to flow in remaining lighting elements in the series circuit.

13. The resistor bypass circuit of claim 1, a respective resistive bypass resistor being connected in parallel with more than one light source, the failure of one of the light sources thereby only affecting a limited number of the plurality of light sources.
