Fog lights - seen it all now!

[Burple]

Jeez.. I bugger off on holiday for a week and you all have a fog light "discussuion" without me!!


Now that's just rude!!

I would guess 1 in 10 drivers I passed yesterday had their fogs on. Visibility was poor though - as the Earth curved you couldn't see over it. Perhaps these eeejits thought it would help them see into the next dimension or something. Also passed a couple of tw@ts with their sides and fogs on. Words fail me.

Fog lights are not meant to make you see the road better, they are there to make you morer visible to oncoming traffic, hence they dazzle other drivers in normal conditions

I thought the idea was that they reduce the glareback from the fog by sitting closer to the surface of the road

You thought right! That's why there is a maximum height for fitment. The rears are obviously to increase your visibility to others, but that's not the primary purpose of the fronts.

It's a common misconception! Next time you are driving in really, really thick fog on an unlit road, try driving with just sidelights and fogs; you get much better visibility than with headlights on, even just dipped beams as the headlights just bounce right back at you from the fog, dazzling you. Not sure the highway code advocates this approach though. Of course the distance you can see is very short, due to the fogs throw, but headlights don't make this any better, they make it worse.

Actually, they are designed to fire light low and to the sides so that on thick fog you can follow the road edges.

Thats my understanding as well
