Janey,
Interesting decision from Coachman for a couple of reasons.
First, I happen the think it is a pretty important safety feature to have a reversing light, not so you can see with it, but because it tells people behind you that you are reversing.
Second, I recall a couple of years ago, during an MOT test on the Volvo estate we had at the time, mentioning to the tester that one of my rear fog lights needed a new bulb because it wasn't working. He laughed and said that Volvo deliberately left the bulbs out (and sometimes disabled the wiring) of one of the reversing lights because in the UK it is illegal (vehicle contstruction regulations, I think he said) to have two reversing lights. Apparently they were banned because of the danger of people thinking they are brake lights. He was a part time policeman and also used to train coppers in vehicle law. He reckoned there was barely a car on the road that could not be legitimately pulled over by the police and that this was one of the main reasons. I never did bother to check whether he was spinning me a yarn. It always struck me as an unlikely story because so many new cars still have two rear fogs. If I ever have time I will try to remember to check; and if he is still right we ought to pass the info on to Coachman.
Cheers,
Mike A
