The invention features an apparatus including a first portion defining an optical axis and configured to connect to an optical fiber, a second portion having a reference surface configured to connect with a terminal, and a third portion between the first and second portions. The third portion bends more easily than either the first or second portion to permit adjustable alignment of the optical axis relative to the reference surface.

A helmet-mounted wireless frequency-modulated infrared beam-actuated auxiliary brakelight system capable of reliable operation in all ranges of ambient light while permitting the rider to turn his head from side to side over a large angle approaching 180 degrees or more. The system comprises a frequency-modulated infrared transmitter, in operative combination with a switch for detecting brake system actuation, and a helmet module, including a frequency-modulated infrared receiver and decoder in operative combination with a stop light. Brake system initiation results in switch actuation which causes the transmitter to emit a beam of frequency-modulated infrared energy towards the helmet module. When the beam is received at the helmet module, it is captured using a lens in operative combination with a novel lightpipe which ensures reception over a 180 degree angle. The infrared energy is then transmitted through a solar filter which further discriminates between solar infrared energy and the infrared beam from the transmitter, before being received at an electro-optical circuit. This circuit decodes the frequency-modulated infrared energy and activates the auxiliary brake lamp.
