Parallel/series LED strip

A light string comprising:

• a flexible electrical cable including a pair of parallel conductors, a continuous series conductor and an electrically insulating material covering for the electrical conductors, the conductors having the insulating material therebetween;
• a first plurality LEDs mechanically affixed to the cable and electrically connected to one another in parallel;
• and
• a second plurality of LEDs mechanically affixed to the cable and interposed between two adjacent LEDs of the first plurality of LEDs, wherein the second plurality of LEDs are electrically connected to one another in series.

A light emitting diode (LED) light engine comprising:

• a flexible electrical cable including first, second and third electrical conductors and an electrically insulating covering material for the electrical conductors;
• a first socket housing mechanically affixed to the flexible cable;
• a first LED received in the first socket housing and electrically connected to the first electrical conductor and the second conductor;
• a second socket housing mechanically affixed to the flexible cable;
• a second LED received in the second socket housing and electrically connected to the second electrical conductor and the third conductor;
• a third socket housing mechanically affixed to the flexible cable;
• a third LED received in the third socket housing and electrically connected to the second conductor at a first location and a second location that is spaced from the first location along the second conductor, the third LED being interposed between the first LED and the second LED;
• and
• an insulation member disposed between the first location and the second location that separates the second electrical conductor to prohibit flow of electricity.
