1. A lighting system for a vehicle, the vehicle having a battery/ignition voltage, said lighting system comprising:

  • a sealed unitary light module disposed at one of (i) an interior portion of the vehicle and (ii) an exterior portion of the vehicle;

    said sealed unitary light module comprising at least one high-intensity power light emitting diode;

    said high-intensity power light emitting diode emitting with a luminous efficiency of at least about 7 lumens per watt and passing a forward current of at least about 350 milliamps when operated at its operating voltage;

    said high-intensity power light emitting diode having an operating voltage in a range of about 1 volt to about 5 volts;

    wherein said high-intensity power light emitting diode emits white light with a luminous flux of at least about 25 lumens when operated at its operating voltage;

    said sealed unitary light module including a heat dissipating element and wherein said high-intensity power light emitting diode thermally couples to said heat dissipating element;

    said sealed unitary light module including a lens;

    a voltage converter, said voltage converter comprising a DC to DC converter; and

    wherein said sealed unitary module is removable from said one of (i) an interior portion of the vehicle and (ii) an exterior portion of the vehicle as a unit.
