Let's have a general discussion on fog lights

Thank god they're finally doing something about fog lights. I'm a country driver and it's a b.. pain to come over a slight rise at night and some idiot has his/her fog lights on. If I have passengers on board it often sparks a conversation about a 'look I've got fog lights' driver who doesn't know the road rules and is inconsiderate of other drivers.
Use low beam or running lights if you have them during the day to stay visible, at night use low and high beam appropriately.
Add fog light users when there's no fog to those who don't dip their lights.

Pet peeve - drivers with fog light on. So many dont realise fogs on equals rear fog as well shining in face of driver behind.

It has to do with what is known as "Rayleigh Scattering" and it's all to do with particle sizes and wavelengths.

Do you ware HIGH VI24/7. Flouro PJs and all? [bigsmile]

My wife was driving her B class Mercedes (well gone now) with its fog lights on (not many of them had the fog lights). They were dazzling and super bright. They were mounted low close to the bottom of the front spoiler.

So one time I drove the car, I thought I'd turn them off ... and I couldn't. The switch no longer turned them off. Eventually the whole switch failed and that caused me to replace it. Replacement cost was I recall around $580. But fortunately they write off B classes (the first series of them sold here) with little damage, so at a Mercedes parts (and many others) place out Dandenong way I bought the same switch (but less than a year old) and it worked .... I think the fogs turned off, too. Yeh - they did ... those light on really bothered me.

Its not only the driver's fault when a fog is left on.

With the Mercedes, the rear red bright light at the back, was a separate switch ...

I could never understand why on a Euro car, the fog lights were so extremely bright ... utterly dazzling at night time.

So, what is the difference? I thought fog lights weren't meant to be dazzling bright. I know people who drive with their fog lights on all the time. "I want to see and be seen." they say.

What is your opinion?

Read the manual for your vehicle.
If the lights you have on are operated off a switch that has a Headlight symbol with what looks like 2 S's superimposed over it and there's a green or Yellow corresponding lamp illuminated on the dash, you haven't got a leg to stand on.

None of my cars, except a Moke, have fog lights. None have daytime running lamps.
The Moke fog lights (which are yellow) switch the headlights off when they are switched on. I wired them that way.

Well you've got nothing to worry about then have you.

I have been using a set of PIAA Off-road yellow fog lights for years.

As said previously, in order to get the best results they are mounted low on the Defender bumper and are aimed down. We get a lot of fog in the mountains and I appreciate the extra visibility they give.

I also use them at night in clear weather, they illuminate the road in a crescent shape few meters in front of the car.

i have to confess, last sunday night i got pulled over while driving with fog lights on.

was given a random breath test, and sent on my way, fog lights were not mentioned.
