Any question answered...

I thought there were specific laws about lights, the rules about reflectors only aply to bikes as sold. So if you buy a bike and take the reflectors off you aren't breaking the law?

Well that's what I thought originally but the highway code says:

It MUST also be fitted with a red rear reflector (and amber pedal reflectors, if manufactured after 1/10/85).

I've found some clarification from the CTC and in the actual legislation (http://www.legislation.gov.uk/uksi/1989/1796/contents/made)

Pedal Reflectors
Four are required, coloured amber and marked BS6102/2 (or equivalent), positioned so that one is plainly visible to the front and another to the rear of each pedal.

But is any of this enforced? I don't know many cyclists who ride with reflectors so are we all throwing away our defence in the case of an accident after dark? Or is it generally ignored?
