Wondering what the convention is with leaving the driving/fog lights on all the time. I do notice that when they are on, they increase the peripheral lighted area of the headlights which can aide in safety and driving visibility, not just looks.

Personally, I don't use the fog lights in daytime, or in normal night driving. I do use them in rain, fog or other situations that I feel demand their use.
I don't like driving towards cars and trucks with their fog lights on when they don't seem necessary, so I extend the same courtesy.

I keep my fog lights on all the time when the headlights are on. I don't get why people want their fog lights on without their headlights. It seems to be a trend that started in the 90's that hasn't faded out yet unfortunately. I think it looks silly and always laugh when I see someone do that.

I agree, fog lights are not adjusted like head lights and can be blinding to oncomming traffic.

I would hope that most, if not all, automobile enthusiasts would know that FOG lights are supposed to be aimed at the lowest possible level so that they won't illuminate the fog and blind the person driving the car that is using them. If real fog lights are aimed so badly that they are blinding oncoming drivers, perhaps you should take the blacksmith anvil out of the rear of the car so it won't keep affecting the gas mileage too.

The problem is that many jerks put auxiliary lights on their cars and then use extra bright bulbs and then aim them much higher than they should so that THEY can see clearly but they blind everyone else on the road. Those people should be shot, and I expect that some are (in some neighborhoods).

Take a look at the lighting pattern on a wall in front of your car. The regular beams have a pretty sharp cutoff. The fog lights are supposed to be lower than those, and the high beams, which in most cars are designed to only work when the fog lights are NOT on, are the highest pattern of all. A fog light that goes above the low beams is not only useless, it is dumb.

Actually, in retrospect, I am pretty sure that what we have on our cars might better be considered an auxiliary driving light, which is there for the looks rather than for use during an actual fog event. The cutoff is not sharp, the pattern is too general, but the light isn't all that bright and probably isn't going to bother people unless you put brighter bulbs in them.

I actually had some experience driving in dense fog yesterday. I drive in it for about 30 minutes with no more than 10 feet of visibility in front of me. I had my fogs on as I always do. I turn then off and I could actually see more ahead of me but less to the sides if me.

Fog lights are low to the ground to let the light shine on the road while cutting through the least amount of fog. Fog reflects the light and blinds you more. The perfect scenario for driving in the fog is to have good low fog lights on and headlights off. Headlights are higher in the air and actually reflect more light back.

Also, fog lights do not need to shine a mile down the road, if you are in dense fog, you should be driving MUCH slower (remember the old rule, don't overdrive your headlights?)

We have fog now and then where I live but not often is it so dense to slow me down to 5 mph. I do wish I could turn the fogs on and the headlights off though, just for that once in 5 year occasion.

I will only use the fog lights on rainy nights turning into dark streets. If I want looks, well, I upgraded to the LED low beams. They look way cool enough. :) And then I don't have the chance of burning out a fog light too soon and look like a dork driving down the road with only half of a cool looking fog light...

You know back about 15, 20 years ago, only the premium cars have factory installed fog lights. It was kind of cool to have the fog lights on to show that yes your car has fog lights! Now they are pretty much standard on most cars. Maybe I am older now, but it doesn't really look that cool running with fog lights unless it is really foggy! :p One time I forgot to turn off the fog lights (after a really foggy morning), my first thought was gee.. I must have looked stupid runny with the fog lights on. It was almost like I forgot to turn off the turn signal... which I do sometime... :p If it gives you better visibility, go ahead, and I don't think it blinds people at all unless you are on a lifted Monster Truck.

Sometimes I'll tell other drivers: "Hey! Your wipers are not on!" To which they'll reply: "But it's not raining!" So I'll respond with: "But it's not foggy, either!"

Oh, I love that one :)

And another one that bugs me is when the rear fog light is on..... sad thing is, most drivers don't even know that extra notch on the fog light switch is for the super bright rear facing light. doh!

Wait a minute, are you pulling my leg? The CT has rear fog lights?? Oh I have to try them out! I have them on my old car and I use them all the time.... to make the tail gating car hits the brake when they thought I am starting to go reverse! Works every time.

There are some countries that require them. I bet those are the only places that get them. If we have them, they are well hidden and concealed.

On my Australian (rhd) car, I have a reversing light in the left rear tail light assembly, and a bright red fog light in the right hand rear tail light assembly. People often tell me that one of my reversing lights is not working, and I have to explain.

No no... never said that.... But many other cars do, and the drivers leave them on as they do with front fogs or turn signals when they don't need them on. :)

(see, it was a joke to follow up on the humor of the post I commented on)

And, why would you run around with lights on that are not needed at the time. Save electricity :) (can't wait to see the debate on how much power the fogs take and which battery the lights are powered from, etc :)
