Abstract
The invention relates to a device for optimal coupling of light into a light conductor in an illuminating element in a vehicle rear view device, which comprises a light conductor with a coupling surface. The light conductor is placed at a distance from a TIR lens and a light source of at least one LED. The LED protrudes into a recess of the TIR lens, which includes the LED.
