Hi

I drive for a living and I see many cars during the day with their fog lights on. I have noticed over the last year that whenever I see a car with one light out, if you keep looking you will see either the out light come on and the on light go out, both lights come on or both go out. Can't understand whats going on here and it never seems to happen with headlights.

Oh yes... talking of headlights, why do we see so many blown bulbs on cars of today, including tail lights and brake lights. There appears to be no enforcement on our roads.

Number plates completely obscured in filth is another common and illegal sight.

Headlight bulb renewal can entail lots of dismantling, not always obvious how to do it, so put off till owner can afford (or be bothered!)

Defective lights and obscured number plates mainly because the only Road Traffic enforcement these days is done by cameras, how often do you see traffic patrols stop anyone for these offences? Not enough patrols (and too much paperwork involved?).

Even my MAN lorry illuminates a fog light (may be an extra light its got lots built into the headlamp unit) the same side as i'm indicating at appropriate speeds, wouldn't illuminate it at overtaking speed, at first i thought it a bit silly, but when turning into dark wet roads particular right turns where the beam pattern is non existant it's proving itself a very useful thing.

Sure i'm going to regret this post, bound to get drummed out of the Luddites Association, in mitigation m'lud i don't run the DRL's.

But what is the point in only illuminating one? Is it to indicate to other road users "Hey look at me- I'm turning a corner" if not, then two lights are surely functionally better than one?
