The invention provides signalling apparatus comprising: a power source; a light; a switch, operably connected between the power source and the light; and connection means to enable the apparatus to be secured, in use, to a user's hand or wrist, and maintaining it, in use, in a fixed position thereon. The invention provides for the use a range of switch options, including tilt switches, inertial switches and strain-actuated switches. The invention has particular application for use as an indicator for cyclists. The apparatus may comprise a glove (Fig 3) or a strap (Fig 2) worn on the hand or, as shown, a wrist band 17 connected to finger portions 18 by a back portion 19. The switch 3 may be provided on the index finger for actuation by the thumb. Alternatively stretching of the elastic back portion 19 on bending the fingers may actuate a strain-gauge switch. A further embodiment (Fig 9) uses a tilt or inertia switch which may comprise a ball in a tube to operate the light on tilting or movement of the wearer's hand. A timer may switch off the light. |
