What Fog Lights?

I have often wondered how good they really are. they must be as so many people, esp. smaller cars turn them on all the time the lights are on. Actually I have only once come accross a car like this where there actually was fog....

What are people's thoughts on this?

Do a search Nick....you will find out what the opinions are.

Cheers.

You didn't say feral, they deserve Lighforce lights at close range the way they are set up often. Commode ones amongst the worst

Fully agree with you there John, they are great if used for what they were put on the car for which is for fog, and yes they are blinding to on coming traffic under normal driving conditions where there is no fog present, I think they must be one of the brightest on the market, funily enough they are only 55 watt must be the way the lenses are produced, but very very effective in foggy conditions. I have had my wife come up from behind on the m4 here in Sydney and I was in my hilux and rang her mobile (yes I know naughty) and told her to turn the bloody things off as they were reflecting straight through my canopy and onto my windscreen and I couldnt see bleep , told her I would dissconect them if she uses them for any other purpose, although I have to admit I do use them on open road with my hi beam as they really light up the side of the road which is great for scrub land but as with my hi beam I turn them off the instant I see some one approch me, high beam and driving lights.

yeah feral, I should know better....
Doesn't hurt to re-ignite the debate about this one though

Know a certain Bonza bloke who will be now accustomed to the fog, who like his WANKER lights on almost in daylight.

Hi All,
Aren't foglights supposed to be mounted fairly close to the ground?
I would have thought that most of the elevated(lifted) and oversize tyred vehicles on this forum would be far too high to mount foglights effectively.

I was of the opinion that foglights were only compulsorily on rice burners.

LOL

Ford Tcikford drivers, Commodes too, with the riceburners. Never focus them right, just think they look cool. Really UNcool actually and blinders......

I understood the idea with fog lights is to have a flat beam, and mounted low. Idea being that fog often has a clearer area about 30 to 50cm off the ground, and the fog light can shine through there.
Also mount them to shine onto the road in front of the car and reflect back up on the underside of the fog.
Being in sth east Qld, we don't see a lot of fog, only a few days a year, or in the valleys on a cold morning :-). So can't see a lot of use having them here. Good driving lights would be used more.
Can't see how you would mount them on a 4wd with good clearance and not wipe them out on something.
Friend did try mounting a pair back next to the sump guard just in front of the front axle, but projected width of beam is a problem.

Many years (decades) ago I remember reading a test of foglights in a British magazine. One of the things tested for was stray light above the beam cut off.
I wonder if any such test has been done recently.

Also in NSW it is illegal to have fog lights on at the same time as low beam headlights. Why then is it not a requirement of the design rules to have them automatically turn off. Most of them are really driving lights anyway with quite the wrong beam shape for fog. It is also illegal to have driving lights with low beam.
