<p>A bicycle pedal is provided with a power source, such as a replaceable long-life battery or a rechargeable battery, recharged, from an external power supply via terminals on the pedal, or, if required, by a solar panel on the cycle, and an electronic circuit for driving a number of light emitting devices (LEDs) positioned to provide rearward facing constant or flashing red light to warn approaching vehicles. The circuit is coupled to switch means, such as a force sensitive switch, so that the illumination is enabled when a cyclist puts pressure on the pedal. The safety pedal may also be provided with a light sensitive switch that acts as a poower saving arrangement ensuring operation of the electronic circuit only when the ambient light level is sufficiently low to require rearward illumination. The pedal may also provide a green, white, or some other non-red light forward facing from the pedal.</p> |
