Unlock this Hidden Feature in Your BMW

(affiliate links)

In other markets around the world, cars have something called a rear fog light that gives your car better visibility from the rear in bad weather. In the US, we don't have rear fog lights, so BMW disables them from the factory.

Luckily, it's easy to enable them on US spec F30's. In this video, I show you how to modify your headlight switch and how to code the rear fog lights to make them work. It's a simple DIY that takes about 10 minutes, and best of all, it doesn't cost anything!

Well, did not know you guys across the pond didn't have rear fog lights! Very handy here in the UK for those foggy winter mornings!

Great video, nicely done. I'm in the UK so have the rear fogs but interesting to see the differences between the two market specific specifications. That last tip to remove the centre caps though! Thanks for that one, mine are a little corroded and I thought I would need to remove the wheels to pop them off from the rear. 👍

Ok, I pony'd up for a like new OEM UK version of the whole light switch assembly, and just got it in the mail today. Took me literally less than about a minute to pull the original out and replace it. Then opened ProTool and toggled Rear Fog light in FEM AND REM and BAMM! I now have rear fog lights that not only light up the rear lights, but show the icon on the dash cluster when turned on. Thanks Justin. Great how to!! Keep em' coming.

You can get the decal and add it to your button. A quick online search should bring up retailer options. Great vids!

Great video. Thanks. I’ve seen and used the rear fog lights when I was stationed overseas. They really make a difference in heavy fog.

Discount Tire installed my static center caps in the wrong orientation (not centered with the M emblem) and I was about to pop all of my wheels off to fix it, but now I don't have to because of your suction cup tip. Thank you! I didn't even think of that! Keep up the good content!

I just did this on my 2018 330i, was pretty easy to do. Thanks Justin.

I did this mod a while ago and it is possible simply to use a flat trim tool or screwdriver to pop the “switch” out of its housing without removing the air outlet as shown here. But I am glad to have found this video as I really wanted to replace it with the Euro switch housing and just ordered it from Turner… along with some sequential turn signals for the mirrors. And I got those spinners for the wheel centers too. After a while one of them “liberated” itself somewhere so I was forced to purchase another set. Bummer but they’re all still on and do look cool. Cheers!

Wow did this mod in about 10 minutes. Hardest part taking the three tabs off. Thanks for your video.

I love little hidden features like this great video👍👍

Thanks for the info, followed your instructions and now have a rear fog light on a ‘17 320!

[KostasMol]

Nice vid & pleasure to watch as always!

[arthurpayne]

Glad to see you guys in America get fog, as we do in the UK 🇬🇧

[maksimignatenko]

I wish these fog lights were brighter. So I could use them when somebody who drives behind me with their high beams on.

[jg_media]

So chillin so satisfying to watch 👌 looks like I know my next mod to the F30

[faisalmehmood]

I think those floating caps are so cool. I got them for my M140i. Really adds a tiny hint of premium to the look of the car.

Thanks Justin. Pretty easy mod and helpful here in the summer monsoon season.

[hyde_official]

you know what cool man, you used the rear light to create a really nice cinematic looking shot with this practical light from the car. and definitely i am going to do the same fog light hack. looks like you can code it with bimmercode so i'll be doing this mod

[rosemont]

Wonder if this will work on a US F82.
Fun fact, one time I got pulled over for rear fog lights in my old Jaguar. Officer thought my brake lights were stuck on but I'm like those are rear fog lights sir. His reaction was "What in tarnation? Have a good day"

I've had floating caps for years and never had an issue. I do wd -40 them once a year to keep them floating good. I always get comments about them from people. The dealer were the ones who offered them to me when i got my BMW. They always give you a free gift and i took these, no brainer.
