Rear fog light
Rear fog light
I didn't like only the left rear fog light illuminated so being one who wants something different I wired the right rear fog to light up. Quite easy since the right rear already has a wired bulb socket. Wire color is identical for both sides....gray and brown. Just run wire from gray-to-gray and brown-to-brown, add bulb, and voila'! Those who know me know I can't leave stuff alone.
Ding, ding, ding. That's it. I was on a rally a couple of months ago and when we arrived at one stop several people told me I had a light out. I checked and they were all fine. That must have been it. Actually, I've never tried to turn on the rear fog so I don't know if I could repeat the incident.

I guess I'll have to go out and see what my rear fog light is. Didn't even know I had one. I prefer to see where I am going and not where I have been. What is the point of this light?
It's there the same reason you have front fog lights. In a thick fog it's a brighter light for other people on the road to see. I got annoyed from people telling me i had a light out. I actually had a friend in high school with an Audi,we changed the other bulb so many times not knowing why it wouldn't go on haha. It's funny looking back at it knowing it's a Euro thing haha.
If your car has a driver-side rear fog light, then DON'T connect the other/passenger side (its probably lacking the internal reflector anyhow) - its by design that way. Why? - To reduce likelihood of rear traffic mistakenly presuming you've slammed on the brake lights when driving out_of_a_thick_fog. Useful also in dustorms, wildfire smoke etc.
Sure its a European 'thing' re why a DS unit only, but they are the experts with this stuff and they created them decades ago, and it was decided many years ago - to generally run with one, on the driver side for that market.
The old 'ECE 38' design rule for rear fog lights is up for world adoption as 'UNECE 38', the global technical regulations are living documents, with changes made simply flowing down to the consumer with the passing of time. Rear fog lights are widespread outside EU too. Many cars, etc have them here in the Australian market incl Jeep, Dodge for example, though the UNECE 38 rule (our ADR 52 and 13) treats them as optional, for now.
In the US, SAE J1319 is the recommended practice - it should be part of FMVSS108 in my view. Negligent, that they are not mandatory fitment in the US.
Only use a rear fog light when visibility is really bad - 100m or less (50m or less applies in Germany), never use because it is merely 'misty'. In these conditions, a cars standard red taillights are nearly worthless.

Rear fog lights are not common practice in the U.S. I've used my rear fog light once since I've had the car and was told, when we had to stop, that my brake lights were on and the right side was burned out. That's why I decided to wire up the right side. The taillight is already set up to work once you wire it and add a bulb. Internal reflector is already installed in taillight. If the U.S. ever gets around to adding a DS rear fog light I'll disconnect the right side.

Anyway I would have to disagree with this somewhat. Seems like the Brit's like having rear fogs on both sides(Land Rover, Jaguar, etc) while the rest of Europe has it on 1 side only. Surprisingly, the Oldsmobile Aurora for those of you that remember that car was an American branded car, however, interestingly had dual rear fog lights on it. Go Figure.
Sure cons of one side would let people think you have a bulb out while having two lights might annoy people into thinking you're riding your brakes.
My beef is with the American IDIOTS that run these all the time regardless if there is fog or not.
My preference would be a single light in the lower center below the taillights(F1 Style) or slightly off center apart from the normal taillight cluster. This configuration is deemed perfectly legal in many countries.
I am well of that sire, about 12 years ago after watching US news of multi vehicle pileups in heavy fog et al conditions, I set about contacting, initially by phone (my personal phone bills were 'high'), each US states DMV to track down the individual/s responsible for having text included into the driver manual - I write text relating to hazardous weather conditions for driver handbooks in AUS/NZ/PNG based on applicable law and vehicle standards.
SAE J1319 was advocated I recall by a Korean Co circa 1985 and I'd reference this to the various DMV's (from California to NY) that rear fog lights did indeed exist and that I wasn't pulling their leg,- as many DMV and police etc were skeptical, including some of their vehicle standards people!
Of the multitudes of states I dealt with, only New York state accepted my paragraph, and that was after I again had to convince them that rear fogs were 'real'. I pointed out the Year 2000 Oldsmobile Aurora had twin rear fogs in US trim; they included my text in their driver manual circa 2004, and changed a couple of words:-) It remains the ONLY US state to directly teach pupils what rear fogs are, that they do exist, and how and when they should be used.

Your in a great area if you've only had had to use the light once or twice - terrific! That someone following you stated you had a burned out RHS bulb, would indicate to me they ignored your real brake-lights, incl the high-mount! Hope you 'corrected' the other driver.
And THAT was/is the debate (you can Google many such discussion). I accept the single rear fog, agreeing with the Continenial approach, even on caravans! Not going to slit my wrist if I end up driving a car with two either, since its much safer to have the item than not.
You can appreciate my efforts at educating US driver license candidates then, see that NY DMV text Chapter 10 - man, that took YEARS to get through. I'd love to adjust it a bit, but better than NOTHING, which currently applies to ALL other US state driver manuals. Hard to teach folk about *rea*r fog lights when the primary driver training tool mentions nothing, eh? :-)
Agree, I like the centrally mounted single rear fog too - suits many a sports.
Roadside safety - One day, when I get enough energy and don't otherwise pass away of old age or cancer (49yo here); might get around to seeing if we can updates US DOTS warning triangle specification to something decent,- like the UNECE 27R type, then advocate for new US market cars to carry a minimum 1 high-vis safety vest, a la EU continent, and of course the triangle:-) (Each item is up for world adoption via The UN Convention on Road Traffic [Signs & Signals] more recent amendments)

1 time poster just to address foglights? hmmmm...
