Overview
With its fanless design and white or selective yellow color options, the SLF LED has been a popular choice for anyone looking for an upgrade, especially in fog light applications. We're excited to introduce its successor: the SL2 LED! The SL2 features a number of upgrades, including a more compact design, internal driver, and improved reliability. The all-new SL2 LED bulb is a direct plug-and-play replacement, providing a significant upgrade in performance.
Modern Foglights. Replacement LED bulbs are a great way to improve the look of the fog lights on your BMW 3 Series Wagon. Whether you're matching the headlights, replacing worn-out standard bulbs, or just adding some style, this is one of the easiest and most effective upgrades you can make for the overall lighting setup on your 3 Series Wagon.
Optimized Optical Focus. Don't be fooled by high lumen numbers. The fog lights on your BMW 3 Series Wagon are designed to focus light. If the light source in the housing is out of focus, it doesn't matter how bright it is. You won't have a focused hotspot of light to shine down the road where you need it, you'll just have more glare. To fix this, the SL2 LED bulb was engineered to focus light from the same location as the original bulb, preserving the focus and hotspot, with no added glare. It produces a functional beam pattern, with a stronger hotspot for added distance and visibility.
Fanless Design. You may have seen bulbs that use large straps for cooling, or big fans that just make noise. Instead, the SL2 was designed as a compact, fanless solution. But that doesn't mean it's low-power! At 14 watts, the SL2 LED bulb still provides plenty of output thanks to a copper-core circuit board and a thermally-optimized full-metal housing with integrated heatsink. The result is a highly-effective and reliable cooling system, keeping the bulb running at maximum potential without the need for a fan.
Compact Size. The SL2 LED bulb is compact in size, not much bigger than a traditional bulb. The integrated internal driver allows the bulbs to easily fit inside the housing on your 3 Series Wagon without the need to tuck a driver away. Installation is easy - simply remove the original bulb, and the SL2 will fit in its place, and plug right in.
White or Yellow. The SL2 is available in 6000K Cool White or Selective Yellow. The 6000K Cool White color temperature provides a more modern appearance and matches most OEM lighting, while the unique Selective Yellow color is great for high contrast, which some find beneficial in inclement weather. Both color options use multi-die automotive-grade LED emitters for superior performance.
Brightness. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house, and provide you the real numbers to compare. If you're looking for the maximum output available, we strongly recommend the SL2 LED, which is a bulb specifically designed for fog lamp applications.
Reliability. Every part of the SL2 LED was designed for reliability, from the custom wiring, to the exclusive aluminum castings, to the integrated driver with built-in circuit protection. The SL2 was put through its paces in our environmental testing chambers - where the bulb successfully performed through dozens of thermal cycles, from -40 through 85 degrees Celsius (-40 to 185F). Whether you're in the Sahara or northern Canada, the SL2 will keep performing for years. It's even compatible up to 30V! We're so confident in the SL2's reliability, that it's backed by an industry-leading limited LIFETIME warranty. See details at
