1. A serial light emitting diode light string that does not use a rectifier comprising:

  • a plurality of bidirectional light emitting diodes, each of said plurality of bidirectional light emitting diodes comprising;

    a first light emitting diode mounted on a first wafer that is encapsulated by a lens, said first light emitting diode having an anode and a cathode;

    a second light emitting diode mounted on a second wafer that is encapsulated by said lens, said second light emitting diode having an anode that is electrically connected to said cathode of said first light emitting diode to form a first node and a cathode that is electrically connected to said anode of said first light emitting diode to form a second node;

    a serial string of said plurality of bidirectional light emitting diodes formed by connecting said first nodes of each of said plurality of light emitting diodes to said second node of another of said plurality of bidirectional light emitting diodes;

    an alternating current connector attached to said serial string of bidirectional light emitting diodes to form said light emitting diode light string, said alternating current connector providing alternating current to said serial string of bidirectional light emitting diodes, without a rectifier, which causes said first light emitting diode to be illuminated while said alternating current is positive, and which causes said second light emitting diode to be illuminated while said alternating current is negative, so that said bidirectional light emitting diodes do not flicker and have an extended life, since each of said first light emitting diode and said second light emitting diode is illuminated for a half of a cycle of said alternating current.
