DISCLOSED IS A ONE PIECE LIGHTGUIDE (24) STRUCTURE HAVING AT LEAST TWO LIGHTGUIDES (22, 24), ONE OF WHICH (24) CAN BE MOVABLE WITH RESPECT TO THE OTHER (22). IN A PREFERRED EMBODIMENT, THE LIGHTGUIDES ARE INTERCONNECTED BY A RESTRICTED LIGHT PATH STRUCTURE (28), IN A PREFERRED EMBODIMENT, A LIGHT DISSIPATING SPRING WHICH MECHANICALLY INTERCONNECTS THE TWO LIGHTGUIDES BUT SERVES TO RESTRICT ANY LIGHT TRANSMITTED FROM ONE LIGHTGUIDE TO THE OTHER. THE LIGHT PATH RESTRICTION IS CREATED BY DISPERSING ANY LIGHT TRANSMITTED ALONG THE SPRING, REFLECTING LIGHT BACK TOWARDS THE ORIGINATING LIGHTGUIDE, TRAPPING LIGHT IN VARIOUS LARGER CROSS-SECTIONALAREA PORTIONS OR VARYING COMBINATIONS OF ALL THREE. IN A PREFERRED EMBODIMENT, A LIGHT DISSIPATING SPRING COMPRISING THE THREE LARGE CROSS-SECTIONAL AREAS (44, 46, 48) CONNECTED IN SERIES BETWEEN A FIXED LIGHTGUIDE AND A MOVABLE LIGHTGUIDE BY SMALLER CROSS-SECTION PORTIONS (38, 40, 50, 52) WHICH SERVE TO MECHANICALLY INTERCONNECT TWO LIGHTGUIDES.
