Abstract: There is described a handlebar mountable bicycle light for fitting to a bicycle handlebar (3) between brake levers (4). The bicycle light comprises an upper cover (5) and a lower cover (6) which are preferably made from injection molded plastics and of a clam shell type arrangement able to receive handlebar (3) and rigidly retain light pipe assembly (7) with cover screws (8). Lower cover (6) contains an aperture (14) through which the handlebar stem (9) extends. The light pipe assembly (7) comprises a transparent rod-like light pipe (18) with LEDs (26) mounted at each end of the light pipe (18). The light pipe assembly 7 further includes heat sinks (24) to draw heat away from the LEDs (26). The arrangement is such that when the bicycle light is mounted to the handlebar, the heat sinks (24) are in contact with the handlebar so that heat from the LEDs may be conducted via the heat sinks (24) to the handlebar material.
