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.

XML2: Two opposing genuine CREE XM-L2 chips, driven at high power by self-contained regulator unit, in an attractive cast-aluminum housing. Fully waterproof, non-polar, modular design. 

Fitment. SMD, HP, and XP bulbs use an inject-molded terminal, with a full-size base connector, designed for exact replacement of your factory bulb. The XML2 bulb fits in the same way, but also requires an additional 2" of clearance behind the bulb socket- see pictures.

Included in your order is TWO BULBS.


These LEDs illuminate in a crisp, bright, cool white hue. The XML2 is also available in natural white, pure white, and yellow.


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.
XML2: 1410 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. Highly Recommended Review by BrisketRobot

    I don't usually review products but this company is worth noting, their customer service department is stellar. I have several of the Diode Dynamics lights installed in my 16 STi and could not be happier. The lights look great and, to the point of customer service, any issues I had were addressed promptly and efficiently. They stand behind their products and truly guarantee 100% satisfaction, don't go elsewhere, order your parts here! (Posted on 8/3/17)

  2. Awesome lights Review by Edgar

    I bought these lights last year of 2016 and one of it died after a year. I contacted customer service and emailed them and Corey was awesome. He replaced my lights and I got them w/in a week here in Canada. These lights are so bright and look so good on my car. I would definitely recommend it to all my friends. (Posted on 5/25/17)

  3. Amazing product Review by Jon

    Best fog lights for the newer model wrx/sti, not only do they last longer than the stock halogens but they give better visibility, especially in inclement weather. I hated the stock halogens, never understood why these cars just didn't come with full LED lights. These fog lights illuminate the road better, they match perfectly with the stock low beams on the limited models, and give the car a nice clean look. Install took me about 20 minutes but if you know what you're doing then it shouldn't take longer than 10. I would definitely recommend this product, and diode dynamics offers a 3 year warranty so you can't go wrong. (Posted on 10/5/16)

  4. Amazing quality! Review by George S.

    First off I would like to say that I strongly dislike the look of halogen bulbs on my vehicles. I did research for a few weeks and decided to give these XML2 bulbs a shot. These bulbs are VERY bright compared to halogen and in my opinion are as bright as HID lights (and are rated to last almost twice as long as HIDs). I had basic LED fog lights in my old Scion Tc which were nothing but for looks, these bulbs are amazing and light up everything ahead. A friend of mine recommended Diode Dynamics and the quality of the bulbs has exceeded my expectations. I would highly recommend this company to anyone wanting to increase visibility and improve the looks of their vehicles. Not to mention, most other companies have 1-2 year warranties for their products and Diode Dynamics has a 3 year warranty which was one of my main selling points. (Posted on 9/17/16)

  5. Awesome Review by Andre

    These were exactly what I wanted them to be! The bright white looks great instead of the ugly yellow stock fog lamp. And they only took about 10 minutes to install. I definitely recommend these fog lights! (Posted on 5/2/16)

  6. Expensive, But Worthwhile Review by Tha

    I purchased the 5000K fog light with the LUXEON LED replacement housing for my 2015 Subaru WRX.

    The fit and finish of these bulbs are amazing, and they are much more substantial than the OEM housings that come with the car. This product is truly plug-and-play, albeit some assembly is required (although minimal).

    The bulbs come with the wires detatched from the harness that plugs into the car itself. In order to determine what the orientation is, orient the plastic adapter plug so the broad side with the little nub is aligned with the car's harness so that they will "click" into place. Now how should you orient the wires? Positive to positive, and ground to ground: the car's positive wire is white, and the ground is black. The fog light's positive wire is red, and the ground is black. All you have to do is orient the wires so they will click together! If you're not sure, you can also test fit the prongs with just the bare metal tips and see if it works or not.

    One quirk I found is that the screws that come with the lights only fit one of the two mounting positions on the car. I had to use the OEM screw to secure the top, while the supplied screw works with the bottom.

    The light output is noticeably brighter than the Christmas lights that came from the factory. The color is indeed pure white, with little to no hint of blue as far as my eye can tell. The cutoff is solid, and I have no doubt these babies will last longer than halogen bulbs.

    I'm amazed by how much more light this thing produces compared to the 19W OEM halogen bulbs!

    I definitely recommend these, especially in the replacement housings just to make sure there's no extra glare or anything! (Posted on 6/24/15)
