In the early hours of Friday morning I had a Newcastle run, on the way there the fog was thick enough to cut with a knife, I don't have fog lights so had to rely on the dipped beam and crawl along

If I fitted a Hid kit would this help or would you get the light being thrown back just like using high beam

My xenon's are worse in the fog than halogens; they are brighter so the reflection off the fog is even more intense.

Saying that the fogs aren't particularly effective either.

Slowing down and 'crawling along' is probably the best solution!

The brighter and whiter the light (as in Xenons) the more scatter you get in the fog resulting in reduced visibility.

One reason why I can never understand why people insist on 'upgrading' their front fog lights.... ooh sorry it's because they look cool isn't it?

FWIW I do over 100K miles PA and can count on two hands when I have really needed front fog lights on.(and yes I regularly drive in foggy conditions - just rarely when front fog lights actually improve MY vision)

What I did was use the load dial and drop the dip beam down slightly down to around 1.5 I think it was, then used main beam this lowers the headlights so made it easier to see a bit further ahead, as the main was hitting the road earlier

I agree the factory fit HID set up on the pre-facelift was really hard work in fog at night - very bright with a sharp horizontal cut-off. I found it better to drive on fogs alone (yes - I know that is BAD).

I haven't experienced fog in my Scout which has AFSII - I'm hoping its better, but we'll see.

I once saw a skoda with the old french type lights fitted in the fog lamps, i have no idea as to how, were the lamps came from but they would be great in the fog.

As others say it is rare that fog is that bad, but on my last car with Xenons (BMW) I seem toremember that I thought the Xenons on dipped were better than an earlier car with standard Halogen. At the time I had put it down to the fact that Xenon have more UV content (hence more blue tint), so narrower wavelength, so will scatter less for a given density of fog. If I remember my physics when you have a narrow aperature that is approaching its wavelenghth you get fringes, or spreading of light. With UV being narrower wavelength I would have thought you would have less spreading. However, matbe my memory and physics knowledge is fading fast

Although, as others say, any reflection you get will be more with Xenons.

I think the idea of front fogs is that they are lower, and fog forms a little bit above the ground. So you get a bit of illumination cutting through the fog, so maybe need to turn off dipped all together when driving with fogs on. Can't remember if that is possible on my light control since the fogs are on the same switch as lights.

I think you can switch on the fogs by pulling the switch out when in the side light position, thus the dipped beams are off.

Yes it is possible.

The switch won't pull out to the first position (front fogs) or second position (front & rear fogs) when in '0' or 'Auto' but they will when the switch is turned to either sidelights or headlights.

I guess this means that Skoda also believe fogs alone may offer more visibility than fogs and headlights combined in certain conditions. Not sure on the legality of this for driving on UK roads though?

Anyone living or travelling through London at night will confirm this is possible on most cars, as there are numerous drivers idiots who drive ether on just sidelights or sidelights and front fog's at night

I once saw a skoda with the old french type lights fitted in the fog lamps, i have no idea as to how, were the lamps came from but they would be great in the fog.

It used be a case of simply spraying the headlight / fog light with a special yellow paint.

Some manufacturers actually applied in the factory for the French market...

Thats the whole point... Dipped or full beam headlights in fog are better than useless, hence the fog lights are able to be used with only the sidelights on, as mentioned earlier the fogs are set low which gives less glare and can sometimes cut under the fog to give better visibility... Also as mentioned many idiots use this function to look cool (sorry, like idiots)...

And as we all know driving at night with fogs when not needed and dazzling oncoming traffic is breaking the highway code.....

I have my fogs in Yellow, just get some yellow lamin-x and apply it to the lens of the light

Pure white or blue light (what HIDs produce) are useless in Fog. What you need for driving in Fog is Yellow lamps.

This website explains it very well
