note that

- there is (apparently) no minimum height for a front light. Max =1500mm
- the range of permissible rear light heights (350-1500mm) is not the same as the range of permissible rear reflector heights (250-900mm).

Thanks Brucey - somehow I knew you'd be the first to answer.
And thanks to everyone else for taking the time and trouble to answer.
And as for Halfords..................... :( :shock: :cry: :oops: :roll:

They don't know what they are talking about (as I think you know). The requirement for front lights long pre-dates WWII. The CTC were famously involved in a debate during WWII, when the requirement for rear lights was introduced. It happened because blackout requirements meant that car front lights were dim, so making bikes carry rear lights would help to compensate. WWII happened a little before 1988, for those whose history is a little shaky.

The CTC was not opposed to the extra safety per se, of course, but was concerned that what was proposed as an additional safety measure would quickly become a basic requirement, and so the responsibility for safety would be further transferred from the driver, as source of the danger, to the potential victim. That indeed is what did happen very quickly. Instead of courts saying, "What, he had a rear light, and you still managed to hit him?", they said, "Oh, he had no rear light, so of course you couldn't see him!", even though, at least in principle (and blackouts apart), the assumption beforehand was that drivers could see cyclists without rear lights.

I've changed my batteries on the move before (yeah yeah I know - don't do as I do, do as I say :roll: )
Kinda of think that even Ethan Hunt (mission imbecilic) wouldn't change the batteries on the penny fart whilst cycling at 20mph :lol:

Maybe Carfords are actually suggesting that we cycle at least 1500mm off the road, preferably in a ditch or otherwise where we won't interfere with the smooth progress of all their HID and LED belighted car drivers..... :|

I seem to remember reading that it became a legal requirement or maybe only a recommendation,that the back mudguard was to be painted white at the rear during the war.
