Can you use flashing cycle lights on a motorcycle?

Some riders are starting to use flashing bicycle lights in addition to their normal dipped beam when they are riding through heavy traffic.

The trouble is that it is illegal under the Road Vehicle Lighting Regulations 1989 which say that lamps on motor vehicles have to show a steady light, unless it’s an indicator, emergency vehicle headlamp, a warning beacon or special warning lamp fitted to a Police vehicle.

However if you clip or tape the lights to your clothing, then they aren’t vehicle-mounted and aren’t subject to the lighting regulations…
