I wonder why they chose red as the legal colour of fog lights? Is this colour most visible through fog? Just seems strange to have them the same colour as brake lights.

By a curious co-incidence, red is also the colour of normal tail-lights, and one of the colours which suffers least colour change when viewed from a distance and/or through fog or snow.

Blue isn't all that visible , green is used on traffic lights , yellow/orange for indicators.

Red is already used for "the lights on the back of the car" so that's why rear fogs are red.

There's also only one of them to distinguish it from a car with it's brakes on.

Some cars have 2 like my Felicia.

wow, this is an interesting thread i have been reading. here in barbados, 95% of persons whose vehicles have fog lights use them. down here, the only thing which can reduce your visibility is rain. as for the fogs dazzling drivers, from what i gathered, the thing that dazzles other drivers is when ppl drive with their main beams on. personally, the fogs have saved me from many a pothole (the roads down here are terrible). as for driving with side lights and fog lights on, everyone does it basically until it becomes dark enough to use the headlights.

What are typical speeds like in Barbados? Fog lights don't have the range to light your way at anything over abut 40mph. Also, I may or may not have said it in this thread, but the bright patch you create just in front of the car actually reduces the range that you (and anyone driving the other way, particularly on wet sealed surfaces) can see.

the speed limits here are 60 km/h for main roads and 80 km/h for the highway.

That's what i hate about people using front fogs: the reflection back off the road.

Excuse me, but this thread was aimed at folk who wished to alter the sequence of which FOG Lights they preferred to switch on first, which I have provided a guided set of info as to altering the wiring, of which I have received a number of Silent Thank You's.

May I suggest to all those concerned, whom have poked their noses in as to whether they wish to either Dazzle the car in front or Dazzle the car at their back of them, to start another thread and kindly do something constructive instead of criticising someone who has provided useful info for people who wish to convert.

Hey, chill out. You mod is useful and a good contribution, but mentioning the words 'fog lights' is bound to set a discussion going.

the speed limits here are 60 km/h for main roads and 80 km/h for the highway.

If those are actual rather than just legal top speeds, using fogs and dips might actually make good sense.

Any problems with main beams dazzling is down to the nut behind the wheel not turning them off when he should though!

Independent control is the way: there are very few times in this country where front fogs are actually useful.

You want to live down near me...

During autumn and winter its foggy most mornings and evenings. And when you get sea fog comming in it can be very bad... sometimes you can barely see 5-6 meters infront of you.

So I would say fog lights on my car are very useful.

Personally if you cant see enough to have to put your rear fog lights on you should also have your fronts on.

they should only be used when visibility is around 100m or less.

the whole point of front fogs are light the ground at as low a level as possible to avoid just lighting up the fog in front of you like the main and even dipped beams do.

nothing worse than sitting behind some **** with their rear fogs on in any other conditions unless your blind!

Agree totally.!

Em why? In daylight fog you want as much light power as possible as high as possible to maximise the distance you can be seen from. Unlike at night, you won't blind yourself with reflected light, because the general light level is so much higher.

if its daylight fog and you can see enough not to put your fronts on then why would you need your rears? tail-lights would be good enough.

or if it is strong enough to require your rears then also having your fronts on is also going to help oncoming traffic to see you too.

And if it's at night you may want the hi-vis lights on the back (that won't reflect and blind you) but maybe less lighting at the front where it could reduce your own visibility? So score for rears only?

The fronts are to help you see, the rears are to help you be seen is how I thought of it?

hmm i dont buy the extra reflecting light at the front, if anything the dipped beams do enough of that, i've had fog round here at night that have caused me to run with side lights and fogs at the front so i could see the road and not a white blanket. that was very heavy fog though. fog lights light too low a level to cause any further issues at the front.

Have you ever driven in dense daylight fog? If you had I seriously doubt you'd have to ask these questions.

If the fog is dense (we're talking "can't see 100 feet, never mind metres" dense here) the rear fog(s) will increase the distance that following traffic can see you from: the tail lights probably won't be visible until you've made visual contact with the silouette of the car in front.

The headlights point seems counter-intuitive because most people only encounter fog at night. Foglights are designed to produce a short wide flat beam, to reduce the light that is reflected off the fog at you. This does not increase their ability to penetrate the fog in any way; they work by reducing glare, not magically cutting through the fog. In daylight the glare is not an issue, because the general light level is much higher. We exploit this fact by using the higher, longer ranged, and more powerful main beam headlights to burn our light further through the fog so that oncoming traffic can see us earlier.

very well put, also in this instance you will be aware it wont hurt to have your front fogs on aswell.

i just think its a pointless task switching your lightswitch round the other way when there is no actual need for it.

I'm still certain mine is set as Rear only or Both as standard.

I see no reason to ever have only fronts on, unless you're a [insert here] who thinks it looks cool. But I do see times when you may want just rears and not both.

That's pretty much my point; fronts are useless except in night-time fog, but there is a use for rear(s) plus headlights in daytime fog.

So I'm wondering at what point did Skoda change their mind?

I've not altered my switch and I can only choose 'Rear Only' or 'Both' (53 plate). So when did Skoda stop having (or change to) that you can have 'Front Only' or 'Both' in order for the OP's modification to ever be needed?

Both my Octy (MY07) and SWMBOs Furby (04 plate) have 'Front Only' or 'Both'.

Without wishing to get into the debate about when to use fog lights, I agree that it would be more useful to have a 'Rear Only' option.

ISTR mine being front only or both, on 52 plate.

I have a strange feeling that my wife's 2003 MY Polo 9N is the same - and it does seem logical (without opening myself up to flaming!). I think that the "rules of the road" changed at some point - ie the UK ones, as I think that in the case of my 2000 MY Passat B5, when I add front fogs I might end up being illegal (MOT time) as I have bought a switch that functions as above. On the other hand, at MOT time I could just fit the old switch as having optional lights that do not function does not seem to be the problem it once was. My wife's previous car - a 1994 Fiesta, had both front and rear foglights and they were individually switched - but rules have changed a bit since then!

Remember for those folk that are lucky enough not to encounter fog, the front fog lights are used by the driver to light up the road under the fog - and not to aid the driver in front to see you - using dipped beam in these conditions just blinds you as the light gets reflected back off the fog and avoiding this by just using side lights is both stupid and illegel (the driver in front can't see you at all). Which leads into the next question, why did some manufacturers only allow you to enable the front fogs when the dipped beams are on? (I think that my wife's 2003MY Polo 9N might work like that - but I'll need to check up on that!)

Right I can now correct myself, on the 2003MY Polo, the front fogs and rear fogs can be switched on when only the sidelights are on - and the fronts come on first then the rears!
