Flashing rear light

[Tony Griffiths]

No, lights must be "steady". But, have you noticed that cyclists have found a way around this? If a flashing light is attached to your body, that avoids the attention of Mr Plod. Though I doubt that, in any case, as most bicycles now appear to be festooned with flashing lights, that said constable would not leave his warm station - where he's busy investigating your Facebook posts and "checking your thinking" - to bother with the six reams of paper that must precede an attempted prosecution. If stopped ..... 'ello, ello, 'ello, what's this flashing business then young man? .... you could claim that it was an "occasional electrical fault" while reaching surreptitiously beneath the dash to switch it off.
