I'll admit to be a 'wazock' then for front 'fogs' - but regardless of the law (and I didn't know that front fogs had the same rules as rear ones; thanks for that, though I will ignore it - just as cyclists ignore how bright their lights should be), there are also too many 'wazocks' driving around who fail to realise just how invisible their silver grey cars are under many light conditions - and not only that but how poor front and rear running lights are, such that front fogs are a good and visible alternative.
From the info given here about how far front fogs project, then using them as running lights is far more desirable than any setting of the headlights.
I will have a polite conversation with Mr Plod if he ever does pull me over for illegal use of lights - polite being that I don't intend to change and will regretably waste tax payers' money arguing it in court if needs be. Rob
