1. A lighting device for attachment to a motor vehicle, the device comprising:
- a light module attachable to the vehicle including a plurality of light emitting diodes;
said plurality of light emitting diodes at least including a cluster of at least two white light emitting diodes comprising a first white light emitting diode and a second white light emitting diode;
electrical circuitry for supplying electrical power to said cluster of white light emitting diodes;
wherein said first white light emitting diode of said cluster individually emits substantially white light when said first white light emitting diode is powered by said electrical circuitry and said second white light emitting diode of said cluster individually emits substantially white light when said second white light emitting diode is powered by said electrical circuitry; and
wherein said light module comprises at least one of an interior lamp, a vehicular reading lamp, and a vehicular ground illuminating lamp.

Abstract
A lighting device for attachment to a motor vehicle inside a housing 4. One or more light emitting diodes 9 which emit substantially white light are employed as lighting emitters. On account of the small amount of waste heat of the light-emitting diodes 9 the lighting device can be particularly easily integrated into existing subassemblies of the motor vehicle, in particular into the outside mirrors, inside mirror, trim strips and door handles, and can serve to illuminate the region around the vehicle or the interior of the vehicle.

32. A lighting device/interior rear-view mirror system suitable for use in a motor vehicle, the system comprising:
-
an interior rear-view mirror assembly, said interior rear-view mirror assembly comprising a mirror housing having a driver side portion and a passenger side portion, said interior rear-view mirror assembly further comprising a mirror mount for attachment of said interior rear-view mirror assembly to an interior portion of the vehicle; an interior mirror light module; said interior mirror light module including a plurality of light emitting diodes; said plurality of light emitting diodes at least including a cluster of at least two white light emitting diodes comprising a first white light emitting diode and a second white light emitting diode; electrical circuitry for supplying electrical power to said cluster of white light emitting diodes; wherein said first white light emitting diode of said cluster individually emits substantially white light when said first white light emitting diode is powered by said electrical circuitry and said second white light emitting diode of said cluster individually emits substantially white light when said second white light emitting diode is powered by said electrical circuitry; and wherein said interior mirror light module radiates light downward from a lower portion of said interior rear-view mirror to illuminate a lap region of a front seat occupant of the vehicle. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
