My 2016 Focus RS has finally lost it's first fog light bulb and I'm wondering what the viable options are for AFFORDABLE LED replacement bulbs. There is a thread on installing the fog bulbs, but most of the links to buy bulbs no longer work or don't seem to be the right bulb. I also found out the hard way that some of the bulbs on Amazon that say they fit, DO NOT fit in the Focus RS housing. I also know there are $120 options that will fit, but I'd rather be below $50 for two bulbs.

Anyone have anything they can confirm fitment on the 2016 Focus RS without modification or heat/reliability issues?
Anyone using the bicolor bulbs that fit and work?

I bought a set of Sylvania led fogs when it went on sale +$15 gift card. So $50 and three year warranty

View attachment 348454

Plug and play, no additional tail to tuck in.
Are they noticeably brighter than stock? And they fit inside the housing? The LED's I tried were too large for the housing. So they are normally $75-ish

I have not installed mine, but when I saw this message I went to the garage and start taking out the driver side fog light housing.

The fittings itself is apples to a apples:

The issue is the LED heat sync is not completely round:

Hitting the hole on those two edges:

I'll be shaving one side just a bit to go through, either that or dremel a small notch on the fog light housing.

Some other pressing stuff came up as I have not installed it on mine.

My apologies.

I have installed these "Car-Rover" DUAL Color [6K/3K] LED bulb 2-pack since early 2017 and no issues at all.
But I got 'em thru amazon prime [US Warehouse] for $50 for the set and now appears to be discontinued... wonder which brand would be comparable & last like the Car-Rover ones I have installed...

These LEDs were defaulted to 6K color [white] and I have to push the foglight button off & back on to get it to "flip" to the 3K color [yellow].

My OE foglight bulb on the driver side burned out this morning.

I do have light bulb coverage on my RS. I'll get it swapped out for good ones (taking them out after that and shelf it).

I already ordered the one form Amazon (from @Barksie and @BigFatFlip confirmation) and saving the Sylvania LED probably for my nephews MazdaSpeed6 or the Mrs. C-Max or even my daughter's Aveo.

Is anyone else using the SEALIGHT fog light LEDs from Amazon? I bought a set in May 2019 and everything was fine, fit, color, brightness all were good. It took nearly 3 years before I realized that these LEDs were causing another issue that was so strange that I almost never made the connection. The short of it is they create interference with the FM radio. I had noticed for years that at seemingly random times, my FM radio reception would go to crap, especially any stations that were HD. Since at other times the reception was fine, I thought I had a loose antennae connection. Not sure why it took me so long to notice the seemingly random times it would not pick up any stations was at night. Once I realized that, it didn't take me long to isolate the fog lights as the problem. I found this thread as now I am looking for some replacement LEDs, the dual color ones have piqued my interest, may have to give those a try. I've been wondering lately if the yellow would actually aid in visibility when it actually is foggy like this morning.

I just installed it today since I thought the last time I saw it out it was imagination.

I used a driver than a rachet so I don't over torque the torx bolt.

Damn filament is burnt just enough to intermittently work:

Side by side comparo:

349727


349728


Goes to the housing snug:

I was concern if the heat sink is touching anything:

No touchy!

and the LED are pointed up and down:

Its says it has avg life of 50,000 hours.

I did sign up at their site for additional 6 month warranty.

Can't beat less than $19 shipped.

Just ordered a pair of the ones Barksie linked to.

Damn, Barksie! As many of us you've sent over there you should get a commission from the vendor. Stop by their Business Office and tell 'em Wiley said to take a hundred bucks outta Petty Cash for you! ;):)
