Claim of US Patent No. 10,117,299

1. A light set circuit comprising four polarized light sources and first, second, and third control signal lines arranged in parallel, two of the light sources being connected in reverse polarity with each other between the first and second control signal lines, the other two light sources being connected in reverse polarity with each other between the second and third control signal lines,a) whereby one of the light sources is selectively activated when opposite signals are applied between the first and second control signal lines, the third control signal line being kept in a floating state, a different light source being activated when the signals are reversed with the third control signal line remaining in the floating state, and
b) whereby another of the light sources is activated when opposite signals are applied between the second and third control signal lines, the first control signal line being in a floating state, a still different light source being activated when these signals are reversed with the first control signal remaining in the floating state.
