An interesting thread which, as usual, generates some heat (With, or without, light).
It seems to me, having been around since the 50s, that existing laws are clear. After lighting up time, which is well before dusk, cycles should have a functioning rear and front light, and they should be on.
Arguing about whether they are built into the bike, attached to the bike, or carried in your pocket when NOT required by law to be fitted and on is, surely, immaterial?
Attempts by government to compel permanant fixed lights as an integral part of the bike miss the point and are an unwelcome and (IMHO) unacceptable interference of an individuals right to choice.
There are laid down existing UK minimum standards regarding how much light each lamp must give, which I believe have been the subject of previous threads.
So, what are we left with?
1. Yet again the enforcement of an existing sensible a law, designed to protect the individual without being draconian, is either patchy or non existant.
2. It is left to the individual to choose whether to comply with the minimum requirement or augment it with hi vis clothing, more lights, etc etc.
Perhaps we, as cyclists, should make it clear that we support the law, as good road users, while resisting the compulsory element of these suggested construction regulations? Perhaps we should also be supportive of initiatives to police the use of lights by cyclists at night?
Personally I live in the countryside and prefer to be as visible as possible both day and night. It is more difficult, I believe, to be visible in urban areas simply because of the light clutter, as has been sensibly pointed out elsewhere in this thread, so perhaps more thought needs to be given to visibility in an urban setting?
Freedom to cycle safely within the law is a right to be protected and fought for. Taking precautions to do so safely, both for the cyclist and other road users, is, perhaps, the responsibility that goes with that right.
