Abstract: A micro universal serial bus (USB) socket is disclosed which improves the invisibility of a micro USB port connection, especially in low light environments. The USB socket includes a light source, for example, a light emitting diode which is disposed to illuminate the periphery of the socket housing and around a set of USB connector pins in the socket. Some embodiments include a translucent or semi-transparent casing around the light source and proximate the set of USB connector pins which may be a light reactive polymer that produces photoluminescence when lit by the light source.
