Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

19 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi all, I noticed that I have only the left side rear fog light working. I removed the right light and I noticed there was no bulb in the fog light spot. I have put one in there (P21W) but it does not work. I do not have 12V reaching the rear connector. Is it normal? Do we have rear fog lights only on the driver side or my car has something wrong? Thanks everyone for your help J-F

POST 3Original post

There is only supped to be one, all is well. Unless you have a Range Rover or Jag and want to drive with them on all the time! (sorry, drived me nuts!)

POST 4Original post

The concept of the rear fog light is that it's asymetrical in addition to being very bright and that attracts attention. Can't understand why some people add a second rear fog.

POST 5Original post

Normal on pretty much every german car I've ever had, but I think some other countries (thinking USA) may have both fogs on their cars, at least I feel like I've seen and freaked out thinkiing they were reverse lights.

POST 6Original post

Putting on the rear fog light is a great way to get a tailgater to back off. It is guaranteed to get them to hit their brakes.

POST 7Original post

At least I'm not the only one--I called the dealer when I noticed only one light

POST 8Original post

embarressed to say I have not driven my car in the fog or at night and never noticed the light (or switch) before... but thanks to this thread I looked it up, tried it out, COOL !!! Still, I should have known but I must have skipped that page in the manual? Thanks for the post! Ed

POST 9Original post

Since I deem that I would hardly EVER need a single fog light, in the rear yet, I wired both rear fogs into the brake light circuit so drivers behind me get a more pronounced indication of my being on the binders.

POST 10Original post

Uh, stupid question here - we have rear fog lights? I'm with Ed on this; guess I need to break out the manual.

did that years ago with my first audi. a bit embarassing.

Pull the light switch out to the first "click" activates the front fog lights. Pull the light switch out to the second "click" activates the rear fog lights.

Dude, you're in Washington state and you don't see the need for fog lights? I must have been there the only foggy, rainy month on record.

POST 14Original post

I found 37 threads started with rear fog lights... Anyone this one was a good one. https://rennlist.com/forums/showthre...g+light&page=2

POST 15Original post

Quotes source post: 5763074

German cars routinely come with a single rear fog on the driver's side. (UK code requires them on both side so that's the difference). Many Scandinavian cars come with the single light as well. You should not routinely use the rear fog light UNLESS visibility is so bad that it will be invaluable at keeping from being run into from behind.

POST 16Original post

well... On the stupid wagon here...I finished some work on the front end and took the car for a quick drive. I tested the rear fog light out and its really cool... remember I said "stupid wagon" There are front fog lights too!! Man I feel stupid. I use the lights in the day but I never knew I had fog lights front and rear... Man what a great day for me! Dipsh*t LMAO OK beat me...I deserve it

I would love to beat on you, but I couldn't do as good of a job as you have done on yourself! However, if you were Phil G. , then I woukld give it a shot!

POST 18Original post

The law in the US states the rear fogs are only one and on the left side. It's DOT.

POST 19Original post

Better tell all the manufactures that have them on both sides in the USA
