A proximity detector that determines an overtaking vehicles proximity (and optionally speed) as it passes the device. The portable device 1 has a video camera 2, a road vehicle proximity detector, a data storage device, a computer processor C and a warning light 4. The device may be used as a bicycle accessory that is fitted on a seat tube, seat post or the seat rails. The device may be powered by a battery 5 and a voltage regulator 6. The vehicle proximity detector may be in the form of two beam-type sensors (3, figure 2). The processor may be programmed to record and overlay the proximity and video data of an overtaking vehicle onto the data storage device. The warning light may be a single red LED or may be a pattern of lights or infrared light. The red rear bicycle light may have a static or moving warning symbol. The video camera may have a front lens that is recessed into a side to protect it from water spray when used on a bicycle. The components of the device may be contained in a housing that is held to the cycle with a bracket 14.
