Diode Dynamics dioDD0481P 9005/9011/H10 White SL2 Pro LED Bulbs

Features Advanced TST LED Technology for industry-leading performance. Internal cooling for superior reliability. Fully integrated design, no wires or external drivers. Direct replacement bulb with compact fitment. Backed by limited lifetime warranty. Designed and engineered in USA (Patents Pending). Introducing the SL2 Pro LED Bulb! As a replacement for the popular SL1 LED bulb, the new SL2 Pro LED features some major upgrades: next-generation TST LED technology, an integrated top-mount fan, and a fully-integrated, wire-free design. As a direct plug-and-play replacement, it provides a significant increase in output, in a compact package. Next-Generation TST Technology. The SL2 Pro features new thermal separation technology (TST) LEDs. TST LEDs are designed with electrical connections on the top which lowers thermal resistance, allowing the SL2 Pro to run at higher power levels than traditional LED bulbs, while maintaining focus. Correct Optical Focus. The SL2 Pro LED bulb was engineered to focus light just like your original bulb, matching the original beam pattern while providing an increase in total output. Instead of using the smallest LEDs possible which can lead to streaks, lines, and harsh cutoffs, the SL2 Pro was optimized to provide a smooth beam pattern, while maintaining focus. Internal Cooling. The SL2 Pro features an integrated top-mounted fan which provides maximum cooling efficiency, superior thermal management and long-term reliability. Since the fan is sealed inside the housing, there's no concerns about damage from dust or moisture over time. 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. Introducing the SL2 Pro LED Bulb!

• Molded construction with sturdy double terminals
• Direct replacement for your factory bulb
• Increased output with LED Appearance
• Plug and play simple installation

The Diode Dynamics SL2 Pro LED Bulb is a direct replacement for the popular SL1 LED bulb, offering next-generation TST LED technology, an integrated top-mounted fan, and a fully integrated, wire-free design. Its plug-and-play format provides increased output in a compact package while maintaining a focused beam pattern similar to the original bulb.

Designed with thermal separation technology, the TST LEDs help reduce thermal resistance and support higher power levels while maintaining focus. The integrated fan provides cooling efficiency and thermal management, while its sealed location helps protect the cooling system from dust and moisture. The molded construction includes sturdy double terminals, and the fully integrated design eliminates the need for external wires or drivers.
