Mike Gouldsborough (NCE 22 June) suggests a clampdown on cyclists riding at night without lights. It is of course already a punishable offence; and he should be in no doubt that police pursue errant riders far more vigorously than they pursue drivers whose offences are merely life threatening.
Danish research found that cyclists riding with lights were more likely to be involved in an accident than those without.
The reasons are obvious - the instinctive reaction of a driver coming upon a cyclist unexpectedly is to brake; if on the other hand they can see you, most will accelerate and try to force their way past.
The claim that accidents are caused by invisible cyclists is not supported by the facts. The overwhelming majority (85%) of accidents involving cyclists happen in broad daylight.
