Fog Light LED bulbs are an excellent way to improve the appearance of your vehicle. From the factory, most vehicles come with halogen bulbs, which project in a yellowish light. By replacing them with LEDs, you can create a modern appearance with the cool white light of LEDs.

The installation is 100% plug-and-play, just replace your factory bulb!

Please note: Fog Light LEDs are primarily for cosmetic upgrade. Some models may not provide an increase in output.


HP48: This bulb is designed with 48 Epistar 3014 LED chips. Thanks to the cap on the top, the light from this High Power Bulb is shined backwards and away from the bulb, not straight out. This means the output is excellent, because it uses the vehicle's housing completely, which then shines the light much more uniformly.

XP80: Each of the four sides of this bulb contains three 5W-rated chips, and the top is fitted with four more, under a projector lens. This is the brightest self-contained automotive LED bulb on the market, and is housed in an aluminum casing with a textured finish for maximum heatsinking properties.

SLF: Six Luxeon ZES chips replicate factory halogen filament for focused beam pattern and minimal glare. Copper PCB core and zinc diecast housing provide superior thermal management and extended LED lifespan. Fully waterproof, non-polar, modular design. 

Included in your order is TWO BULBS.


These LEDs illuminate in a crisp, bright, cool white hue.


Diode Dynamics offers several brightness options so you can choose what fits you best. These options are listed by the design and the lumen output of each bulb, compared to the factory bulb.

HP48: 265 lumens. Slightly lower brightness than factory.
XP80: 510 lumens. Similar brightness to factory.
SLF: 850 lumens. Much brighter than factory. These are bright!

Lumens: BUYER BEWARE! Most sellers just provide "calculated" lumen numbers, based on the maximum potential brightness of the LED chips on the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is not accurate, as the design of an LED bulb does not get rid of heat fast enough to run the LEDs at maximum. 

These "calculated" lumen ratings are much, much higher than the true, measured light output, so it will look like competitors' bulbs are brighter than ours. This is because Diode Dynamics does not provide inflated "calculated" numbers; we believe it is misleading. We test the actual brightness of the bulbs in our lab, to provide real lumen output measurements. Our measurements are accurate, but they are usually much lower than the misleading "calculated" figures. Please click here to learn more about LED brightness measurement.



LED Components. Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means we use only brand-name suppliers such as CREE, Epistar, Cree, Osram, and Samsung.

While Diode Dynamics bulbs may look the same as others on the market, most copycat bulbs use economy-grade LED chips in order to reduce costs. This greatly reduces the reliability and overall brightness of the bulb when you compare it to Diode Dynamics.

Construction. Although LED technology allows for extremely long bulb life, the market is flooded with cheap LED bulbs that fail prematurely due to inferior construction. The worst enemy of LEDs is excessive heat, and when bulbs are not designed properly, they do not disperse heat as well, leading to premature failure.

Off-brand, cheap bulbs exhibit poor solder uniformity, high levels of flux in the solder, uneven chip placement, low-gauge terminal wires, poor assembly, and bulbs held together with inferior adhesives. At best, solder joints will crack and fail on low-quality LEDs after a few weeks of use. In the worst case, these bulbs can damage housings as the extra flux and adhesive evaporates and creates a residue on the lens of the housing.

Diode Dynamics bulbs are produced with modern, computerized equipment, and only the best materials, to ensure complete uniformity, high quality, and long bulb life.

All Diode Dynamics products come with a 30-day satisfaction guarantee and a 3-year limited replacement warranty. For more information, please view the Warranty Information page.

  1. Luxeon LED's Review by Chris

    Bought some Luxeon LED Fogs and followed the video for the fiesta ST fitting and it was spot on. I would say to make it easier for yourself remove the wheel on passenger side of the car as it is a rather tight space and a little fiddly to remove the screw from the bumper. Driver’s side was easier as there was a little more space. Keep hold of the factory screws as the ones provided are a different thread but other than that the Luxeon housing just slides straight in to place.

    Personally I have the lights aimed nearly straight with a slight down angle as they are only 12 inches from the floor and the amount of light output by them is amazing, There are no hotspots and the beam pattern spreads the light evenly right across the floor. You can look straight at them from 2ft above and there is no glare produced either again thanks to the optics.

    Very quick shipping to the UK I think it was 10 days in total and great customer service too, Emails answered quickly I think the first time it was 15 mins and second contact was 8 hours ish. But it was because of the time difference from USA to UK i.e. I know I emailed when the shop was closed so wasn’t expecting some poor sod to climb out of bed to reply to an email at 2AM.

  2. Finally an LED bulb for a fog light that is an improvement over halogen lights! Review by Geoffrey

    I have tried a few LED replacements for halogen fog lights and always been left disappointed, until now! These XML2 fog lights are amazing. I wanted yellow-tint fog lights but did not want to deal with putting film on the lens as everything about the process is a pain. Not only are these XML2 fog lights brighter than the factory halogen lights they have the perfect yellow tint I was after for not only the aesthetic look but also the practical use in fog and rain. From the moment I opened the box I was impressed, the packaging was very high quality and looks like it would protect the bulbs from any kind of conditions encountered when shipping. The aluminum housing has that heavy/quality feel and you can tell the cost of these bulbs went directly into the materials and assembly. These XML2 LEDs are expensive but you are getting exactly what you pay for. In my 2016 Fiesta ST the install was very easy, I had the headlights out already to install other LEDs so I was able to reach the back of the fog lights and install the new bulbs in just a few minutes. The fit securely into the housings and while they do stick out father by about 2 inches they had plenty of clearance, the pigtail harness was also very nice and allowed me to connect it before installing in the housing making it easier to work with than the halogen bulbs. As for the performance of the LEDs - WOW! They produce a much brighter and uniform output than the halogen bulbs. The light coverage is solid from about 1 foot infront of the bumper out to about 15 feet and then slowly fades out to about 25 feet, this allows them to perfectly fill the gap between the front of the car and where the factory headlight coverage starts. The output from side to side is also much wider and fuller. Despite being brighter and providing more coverage than stock they do not blind on-coming drivers. When looking at the front of the car you can tell the fogs are bright, they appear even brighter than the headlights, but they do not blind you with glare. These are worth every dollar spent and I could not be more happy! (Posted on 4/28/16)

  3. XP80 Cool White Review by Eric

    The stock foglights on the Ford Fiesta ST aren't the best and having had a good experience with Diode Dynamics before I decided to purchase lights from them again. I am very happy with my purchase of the XP80 fog lights. As expected the brightness level is similar to stock but I find that the width and length of the beams are greater and overall visibility on backwards is improved. My favorite part about the lights however is the color. I hate the OEM yellowy tinge and these match my LED switchback turn signals perfectly. Install was simple, especially with their YouTube video. Overall very satisfied again as the build and service is unmatched. Now I just need a pair of HIDs to finish out the front end. (Posted on 2/7/16)

  4. Disappointing, but still better than OE fog light Review by Ooklathemok

    I ordered the pure white 5000K XML2 1420 lumen fog lights for my 2014 Fiesta ST. Like all my Diode Dynamics purchases the quality and build is top notch. The installation was fairly easy. Plug and play. Nothing difficult, just working in tight spaces. These are definitely brighter than the oe bulbs. But what disappointed me was the throw. I thought the beam/light would be more dispersed. I found from left to right there was more light dispersed. But the forward reach of the LED as at or just slightly better than the oe fog light.
