Fog lights
Jump to: Newest in thread
I was driving down the motorway the other evening and we had some pretty bad rain, before I knew it visibility was down to may 150m it struck me how few cars had their fog lights on.
I think there is a miss-conception because of the name that fog lights should only be used when it’s foggy.
When in actual fact they should be used when the visibility conditions limit how far ordinary tail lights can be seen.
Anyway that’s off my chest so you can all go back to dogging taking photos of your nobs next to sky remotes and general debauchery |

"They cause glare in rain and should only be used in fog. Hence the name."
This 
Being a biker there's nothing worse than bright red/white lights being magnified by rains spots on your visor ! |

They should hardly ever be used! They should only be used when the standard rear lights can't be seen and when there is a car behind you then you definitely don't need your fog lights on as they can see you ! Seriously pisses me off when visibility is down to 200 metres (us inteligent people call it mist) and all the bloody fog lights come on dazling everyone following them for the next 2 to 3 weeks as the twats instantly turn them on but never turn the bloody things off! |

I think there is probably a distinction to be made as to the type of wet conditions.
If it's just raining then fog lamps aren't appropriate.
If however there is substantial standing water such that there is a large amount of hanging mist and spray, fog lights will generally aid visibility, to a point. |

Do people _genuinely_ think that fog lights “dazzle” them? They are bright but I have never seen a fog light that has “dazzled” me. If you want a light that “dazzles” you then I would suggest pretty much any modern halogen headlight.
Fog lights are much less of a problem than modern head lights IMHO. |

This is what it says on Google.
You must not use front or rear fog lights unless visibility is seriously reduced (see rule 226) as they dazzle other road users and can obscure your brake lights. you must switch them off when visibility improves.27 jul 2022.
Rule 226. You MUST use headlights when visibility is seriously reduced, generally when you cannot see for more than 100 metres (328 feet). You may also use front or rear fog lights but you MUST switch them off when visibility improves (see Rule 236). |

Exactly ! I think that they should also automatically switch off at any speed over 40mph, if the visibility is good enough for you to be going over 40 then you don't need fog lights on full stop ! |

Yes.
Fog lights don’t have a directed beam. It’s there to be seen so fires light out brightly at all angles. A halogen/xenon/led headlight is directed, be it be reflection or projection and therefore will only dazzle if it’s miss aligned.
I hate seeing people put their rear fogs on when it’s raining as it bounces the light off the wet road up at you too.
I can see you… no need for them in the rain. |

Fog lights should never be used in any heavy rain conditions as they actually cause a reflection off the road surface where water is being held and combine that with your fog lights and you will dazzle yourself .
Same as the rear lights of the car in front of you also will dazzle you if you put your fog lights on in heavy rain.
Normal lights,slow down and turn your wiper speed up in extreme rain is what you should be doing. |

Interesting. My experience is literally the polar opposite of yours. I find oncoming headlights far too bright nowadays (directed or otherwise) and have never once had issues with reflected rear lights on the road. I guess that difference is what makes the world an interesting place  |

If you put your fog lights on when visibility was 150 m then I am afraid here in the UK you were breaching the law. Foglights must not be used until the visiblity falls to below 100m, sorry |

I should clarify that I was on a motorway and it was raining, there was enough rain on the carriage way to create spray. The spray acted like fog (which is only water vapour in the air) in so much as it limited visibility. It wasn’t possible to see traffic in front over 100m away even though these vehicles had their headlights on. Fog lights are there to help people see you in conditions that limit vision.
I don’t get annoyed when I see someone has left their fog lights on. Certainly not as annoyed as I would be if they didn’t have them on and I didn’t see them and ran into them. Which incidentally I’d be responsible for. |

My biggest complaint about fog lights and glare is...
I got points and a fine for having them on in rain.
The police car that stopped me a BMW 5 Series, had xenon lights and was litterally blinding the shit out of me... am sure we have all been there.
Yet my low level Christmas tree scale, gass powered lights on my student Peugeot 206 were 'dangerous'.
Seems legit... and am not bitter...
I own a car with exceptionally bright lights now... and I revel in driving behind the police blinding the shit out of them with my lights legitimately.

"Agree, currently having a rear 'fog' light fitted to my motorcycle - really don't fancy being re-endered by a rep in a rush because they haven't seen the pathetic tail lights fitted these days"
Just fit LED bulbs on the back. |

Never mind fog lights, it's the people who change the bulbs and either have a new one that its blinding whilst the other is not bad as its the original or have both of them di. It's so annoying. They are obviously using far brighter lights than they should. |

I hate it the most when it's dark & someone in a car is coming towards you or at the back of you has the lights on full beam.
You have to flick your mirror upwards to prevent yourself being blinded but the git is still shining brightly in your side mirrors. Why?
It's very easy to forget - I get that! Even if I put mine on briefly then drop to normal they still sometimes don't get it? Are people bats?
I hate it when you get home you get that feeling like you have been looking at the sun with colours. Followed by a headache. Gee thanks!   |

I have the same issue though driving a new BMW, people always assume my lights are on full beam because they're stupidly bright, get abuse, horns sounded at me, full beamed by people coming the other way because they don't seem to realise that's what some new cars come with now. Even had to prove to a police officer before my lights were on a normal setting and show them the difference full beam does when used and only then did they shut up and go away.

This is not bragging but most newer cars now have auto dimming mirrors
I’ve not had a car for over 10 years without self dimming mirrors
And the last few cars I’ve owned had auto lights including hi beam so they turn off when the spot oncoming lights and when driving into towns etc..
I do get that the newer cars lights seem to be extremely brighter than their predecessors but that’s progress for ya
As for fog lights most modern cars are fitted with daytime running lights that are often mistaken as fog lights |

Front and rear fog lights have two very different purposes which is why the rear ones are compulsory and front ones aren't.
Your head lights are designed to project light that reflects back off objects in your path, angled such that the light reflected back comes in at driver eye level to make these objects as visible as possible (some new very reflective road signs do this uncomfortably well). Unfortunately this means that high levels of water vapour in the air also reflect this light back and can dazzle the driver. Front fog lights are set low on the vehicle and aimed down so that light from them isn't reflected back at driver eye level making them less effective at illuminating the road some distance ahead but much better at showing the road close to in foggy conditions. This design feature also means that anyone suggesting they're dazzling literally doesn't understand what fog lights are - most often they're confusing them for front spots, they are driver aids designed to be as low dazzle as possible, set on the vehicle so that they shine down onto the road surface, not up at oncoming drivers.
Rear fog lights have an entirely different job. The rear lights on a vehicle are a safety feature designed to make it visible to other road users in low light levels. This requires very little light and in fact being too bright can affect the night vision of drivers behind. For this reason the level of light allowed from tail lights is restricted. Rear fog lights, like brake lights on the other hand are designed to be bright enough to see even in bright day light. This is because a even a regular tail light is often plenty bright enough to show up through fog at night but isn't when the ambient light levels are much brighter. Rear fog lights come into their own when the vehicle is rendered all but invisible by water vapour, either from fog or surface spray (as per the OP) and this is much more likely in day light. Bottom line is, if you can't see the vehicle in front or it's rear lights then you should have your rear fogs on whatever the time of day. If you can see his tail lights then no matter how foggy it is you don't need yours on, they simply wreck the night vision of and driver behind and make following your vehicle very draining while serving absolutely no useful purpose. Unfortunately, many drivers routinely put their rear fog lights on at night when they do no good and make life a misery for other road users but don't bother to put them on in daylight when road conditions mean that using them significantly increases your chances of being seen. I really do wonder what goes through some drivers minds when they're struggling to make out the vehicle in front but don't think that others may have similar issues or when they can clearly see the regular tail lights of the vehicle they're behind but still think that no one can see them unless they bang on a pair of mega bright red lights

You are right. I don’t ride a motorbike as I think it is too dangerous - pretty much for the sorts of reasons you cite. To be honest I don’t know how you would ride in the rain with a visor that is covered in water drops. If my wipers failed on the car I would pull over. |

It is different, the drops on your visor are much closer so somehow easier to see past. Plus,a car windscreen will is a large flat area and gets covered in a sheet of water in heavy rain, that never happens with a visor. In many thousand of miles in a bike I can't say I've ever been bothered by fog lights

Have you been on a motorway when it’s raining, have you seen the spray that comes of cars and lorry’s, bet you can’t see much else can you. It’s appropriate to use fog lights in that situation.
Fog is water vapour in the air that restricts visibility.
Spray is water vapour in the air that restricts visibility.
Ones caused by air cooling to its dew point
The other is caused by fast moving traffic
The net result is you can’t see. |

It's actually illegal to use fog lights when it's not foggy. Really, they should only be used in situations where there a large distances between cars. Once you close to a car with it's fog lights on, they are dazzling and can make it difficult to spot brake lights.

The main problem with rear fog lights being on when they're not needed is they're brighter than brake lights, there's a strong chance you won't see the car in front of you breaking, particularly in bad weather.

The net effect of water spray is significantly different to fog though. The average water molecules in the air are considerably larger than the atomised vapour that makes up fog. The result is that in these conditions the spray increases the glare from rear fog lights making visibility rather than helping it.
The other issue in using fog lights on the motorway is that should only be used when the following vehicles are far away, not when they are up close. This means that to use your fog lights safely you will need to be constantly switching them off as cars get close to you.

Have you been on a motorway when it’s raining, have you seen the spray that comes of cars and lorry’s, bet you can’t see much else can you. It’s appropriate to use fog lights in that situation.
Fog is water vapour in the air that restricts visibility.
Spray is water vapour in the air that restricts visibility.
Ones caused by air cooling to its dew point
The other is caused by fast moving traffic
The net result is you can’t see. "
Just to reiterate :
fog - use fog lights.
Rain - use windscreen wipers, slow down and keep a safe distance.
Glad to help
If you’re still struggling then a quick Google search for the Highway Code will further elaborate for you. |

"They are called fog lights.
They’re not called rain lights or even just lights.

I’m fine with that as advice my problem is that when I’m slowing down the people behind me can’t see you know cos of all that stuff in the air that’s restricting visibility.
If only there was some way to make my car more visible to them. Maybe you could sit on my boot and shout at them when they get too close |

This is what people appear to be missing, rear fogs are not for you to be able to see better, they're so you can be seen. Putting your wipers on isn't gonna make the slightest bit of difference to the driver behind
Maybe the poster above could follow his own advice and Google the highway code.
The overview for adverse weather says
You MUST use headlights when visibility is seriously reduced, generally when you cannot see for more than 100 metres (328 feet). You may also use front or rear fog lights
Under the heading wet weather it says 'the rain and spray from vehicles may make it difficult to see and be seen'
So to re-cap, when visibility is reduced you may use front or rear fog lamps, and rain/spray from vehicles can reduce visibility. Not rocket science is it?

Rockets are not effected by fog. |

"You see people with fog lights on instead of headlights, in all sorts of conditions.."
I drive with my front fogs on all the time, they absolutely do not dazzle other road users (my headlights do that as they are stupidly bright from the factory) front fogs point pretty much at the floor  |
