1. A vehicle illumination system, comprising:
- a light source configured for emitting light for illuminating surroundings of a vehicle, an interior of the vehicle, or both the surroundings and the interior; and
a modulation unit configured for modulating the emitting of the light of the light source, where the emitted light is modulated with a frequency that is high enough so that the modulation of the light is substantially not perceivable by a person.

Abstract
A vehicle illumination system includes a light source emitting light for illuminating the vehicle surroundings or the vehicle interior or both, and a modulation unit modulating the emitting of light of the light source, where the emitted light is modulated with a frequency that is high enough so that the modulation of the light is substantially not perceivable by a person.

37. A vehicle illumination system, comprising:
-
a light source including a plurality of light emitting diodes configured for emitting light in a visible wavelength range to illuminate the surroundings of the vehicle, an interior of the vehicle, or both the surroundings and the interior; a modulation unit configured for modulating the emitting of the light by the light source with a frequency high enough so that the modulation of the light is substantially not perceivable by a person; a detector configured for detecting light; a range finding unit configured for determining a distance to an object on the basis of a distance signal generated by the detector in response to detecting light emitted by the light source and reflected by the object, the light being modulated at a first frequency; and an information transfer unit configured for sending predetermined information, the information transfer unit further configured for controlling the modulation unit so that emitted light is modulated at a second frequency different from the first frequency in dependence on the predetermined information, where the information transfer unit is further configured for receiving information by demodulating a light signal given out by the detector in response to detecting modulated light emitted by another vehicle.
