1. An apparatus for conducting light to a fabric surface, the apparatus comprising:
a light source configured to emit light;
a light guide physically and operatively connected to the light source;
at least one optical fiber bundle physically and operatively connected to the light source;
a circuit board operatively connected to the light source;
a case to enclose the light source, the light guide, the circuit board and a part of the at least one optical fiber bundle; and
a sleeve positioned on the outside of the case, the sleeve wraps around the case section covering the optical fiber bundle;
wherein the light guide is configured to guide the light emitted by the light source towards the at least one optical fiber bundle,
wherein the light source is connected to the optical fiber bundle at a coupling interface, and
wherein the at least one optical fiber bundle comprises fiber optic strands configured to conduct light from the light source.
