I've never seen rear fog lamps and am wondering about this. After playing with the button for awhile, I found the lamp integrated into the rear lights. On mine, only the drivers' side one lights up. Is there something else I have to set to get both to light up, or is this another trip back to the dealer? Can someone please check theirs?

There is only one. Pretty standard on European cars. Not sure if it is a standard to have only one or not. I suspect that by having 2, drivers behind could think that you have laid on the brakes, when in fact it is purely to be visible in fog. Hence, only one makes sense.

As twodivers said, only the driver's side illuminates. Your lights are functioning properly.

There is only one for a reason. If there were two rear fog lights, they would be confused for brake lights... Having driven for extended periods of real fog in Europe (unlike most regions of the US) you come to appreciate why it is only on one side. When you come upon a car with just the rear fog on, you know to be cautious. When you come upon a car with BOTH lights on, you know they are braking or STOPPED and it's time to get on the binders RIGHT NOW.

I've learned something new. Thanks!

Same here, only on drivers side

As others have stated there is only one. I use mine when in heavy fog and when it is snowing hard. I had a neighbor following me home one evening, I did not know he was behind me, he called after he arrived home and said he was glad I had it on as it helped him see me and allowed him to keep a safe distance while also being able to better see and follow my tracks in the snow.

Cyber GS

I do the same thing.

Once upon a time, a long time ago, rear fog lights were an aftermarket, bolt on the left rear bumper BIG rectangular light. Bosch & Hella sold them. In the Rhine valley in winter they were essential. Glad they became standard equipment on Northern European vehicles. I wonder why the US is so far behind?

I think Jaguars have two rear fog lights.

But don't you hate following a car with rear fog on when the weather is nice?

^^^^^^
That I have seen a surprising amount of.

I just checked and my XJ does have two rear fog lights. According to wikipedia, EU regulations require at least one rear fog light on all vehicles but more than one is permitted if desired.

Surprising how many cars have one foglight, and the same spot on the other side is the single reversing light. Ugh.
Glad the ML has two reversers.

Far better to see lights on and not needed than vehicles with no lights on in the dark. Same goes for cars with no lights in the rain or fog during the day.
Better to be seen than to be invisible.

I have been seeing this more and more recently and don't get it.. It's scary the amount of people that just get in and drive without thinking...

Another thing, the amount of people driving at night lately with their high beams on is out of control. I am talking about in populated areas with plenty of street/highway lighting .

There is no need for high beams, all the high beams are doing is blinding oncoming traffic..

venchka

I suppose illumination can be overdone. High beams would be annoying in an urban environment. There is no accounting for the way some folks drive. Appliance operators comes to mind.

If you lived on a country road in a rural location I'm pretty sure your opinion of high beams would change pretty quickly.
A deer or a fox's eyes will glow from very far away with high beams.
With the number of deer on the roads where I live I can't imagine driving with only the low beams.

Cyber GS

You should re-read what I posted..

For me there aren't too many deer or fox's jumping out in front of traffic in or around the NYC area..

I use the high beams when I visit relatives near the Pocono mountains in PA where there is no street lighting and it is pitch black.

On a rural country road yes, not in urban environments where street lighting is not an issue.

And lets not forget about people driving with their hazards on. Here in FLorida when it rains the hazards come on. Not to mention the old folks NEVER turing off their left turn signal. :-)
