The all-new SL2 LED bulb is a direct plug-and-play replacement providing a significant upgrade in performance.Optimized Optical Focus. Don't be fooled by high lumen numbers. Your vehicle's fog lights 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. The SL2 was designed as a compact fanless solution. But that doesn't mean it's low-power! At 14 watts the 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.NOTE: LED bulbs are legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. International legality varies by country.
