as a note, american cars DID NOT come with rear fog lights connected.  switchable rearward facing lights are illegal on automobiles in the U.S.

VEHICLE CODE 
SECTION 25950-25952 

 

(2) The color of foglamps described in Section 24403 may be in the

color spectrum from white to yellow.

 

Which just goes to show, a website may or may not be telling you what you want to know.

That is true for forward facing "fog" lights. Rear "fog" lights can not be amber or white because that would confuse those coming up behind you!

the DOT does not allow rearward facing fog lights, nor any rearward facing light on a switch, on an automobile used on public highways.  i think they figure americans are too dumb to turn them off, and might blind or distract other drivers.  they're not wrong

The U.S. allows one exception to rear fog lights : on first generation Boxsters ( because no one is sure which is the front and which is the back of the car so other drivers are confused if you're heading toward them or away from them .. ). What ?! :-)

ROW cars (at least over here) have 2 buttons at the left of the steering wheel: front (green button light) and rear (orange button light) fog lights.


-the headlights have to be raised to be able to switch on the fog lights

-you can not turn on the rears without the fronts; it does work the other way around (just the fronts)

-amber colour (orange) over here is strictly used for indicators only; front fog lights sometimes can be yellow; yellow head lights are allowed on older (early '90's and before) cars.

-front fog lights aren't mandatory, at least one rear one is



Buttons:


   



Front fog lights:


   



Rear fog lights (middle left and right):


   



Rear fog lights and brake lights on the corners:

The distinction which is being missed here is that forward facing "fog" lights of the amber variety (not white because what's the point - if white worked you'd just put on your high beams and wouldn't need them) have the purpose of illuminating your view through the fog.  The intention of rearward facing so called "fog" lights is to permit others (behind you) to see you better.  They cannot penetrate the fog but your visibility to others is enhanced.  The problem is a protective government which believes that people cannot distinguish between brake lights and rearward facing bright lights which help increase your visibility to others. It took them along time to accept high intensity lights which Europeans had adopted many decades ago. Slowly things are changing.

My S60 has the front and rear fog lights, two switches on the left as stated above. I find the rear ones are a great way to shake tailgaters.

The thing with front fog lights is that they are always mounted close to the ground so they illuminate the edges of the road better, and the beams wouldn't reflect on the fog droplets as much. Not sure if yellow ones would do any good. It seems that car makers put white ones in as standard which makes me believe yellow ones aren't any better.

Both my MB c230 K and Cayenne have switched rear fog lights from the factory and both are US spec cars and both are red.

that's new.  that has always been illegal here, and in fact, the grey market 968s had to have them removed before DOT would sign off on them.

From what I can tell, rear fog lights in the US are legal, just not mandatory:

I was thinking about the fact that the high beams have an auxiliary light in the fog lamp housing, the "flasher" light, and that California law does not provide for a supplemental high beam and yet the 968 got through in California. Go figure...

actually, it does provide for supplemental high beams.  i know because i fought and won on a ticket for those.

24402. (a) Any motor vehicle may be equipped with not to exceed two

auxiliary driving lamps mounted on the front at a height of not less

than 16 inches nor more than 42 inches. Driving lamps are lamps

designed for supplementing the upper beam from headlamps and may not

be lighted with the lower beam.

(b) Any motor vehicle may be equipped with not to exceed two

auxiliary passing lamps mounted on the front at a height of not less

than 24 inches nor more than 42 inches. Passing lamps are lamps

designed for supplementing the lower beam from headlamps and may also

be lighted with the upper beam.

 

The "flasher" light which goes on with the high beams is here defined as "driving lamps".  

The "fog light" falls in the category the code calls by the same name.  

 

But actually the "fog light" as a fog light is impractical because the beam is focused to the lower

portion of the road as Bulti pointed out. The amber light will cut through the fog, the white will glare and

in heavy fog will appear as a wall of white with the lower portion of the road illuminated in yellow.  

And that would be strange indeed. 

 

In practice it would fulfill the function of a passing light except for the height restriction which is 24"

I didn't put that smiley face in there... so gremlins are at work.

"The "flasher" light which goes on with the high beams is here defined as "driving lamps"."


I don't agree. The flashing lights are meant for signaling only and not for continuous illumination of the road. The fog lights have a lower intensity too. I had no problems before with them creating a "white wall" because they are mounted low enough.


The extra set of flashing lights is there because you must be able to signal people with the head lamps down. On most cars this is done with the high beams.


Don't really know how the bumperettes influence this though.
