Diode Dynamics H13 White SL2 Pro LED Bulbs, Part Number DD0488P

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

Upgrade your vehicle’s lighting with the Diode Dynamics H13 White SL2 Pro LED Bulbs, Part Number DD0488P. Designed as a direct replacement for compatible factory H13 bulbs, this pair delivers increased light output, a clean LED appearance, and straightforward plug-and-play installation. The compact, fully integrated design eliminates external drivers and loose wiring for a neat fitment in the original bulb location.

The SL2 Pro uses next-generation Thermal Separation Technology (TST) LEDs, which position the electrical connections on top of the LED package to reduce thermal resistance. This allows the bulb to operate at higher power levels while maintaining a focused beam. Diode Dynamics engineered the optical design to closely match the original bulb’s beam pattern, helping provide smooth, controlled illumination without excessive streaking, harsh cutoffs, or distracting lines.

An integrated top-mounted fan provides efficient internal cooling and supports long-term reliability. Because the fan is sealed inside the bulb housing, it is protected from exposure to dust and moisture during normal use. Molded construction and sturdy double terminals further support dependable performance. These bulbs are designed and engineered in the USA and are backed by a limited lifetime warranty. Please verify vehicle compatibility and available clearance before installation. In the United States, these LED bulbs are legal for fog-light applications only; they are not DOT/FMVSS 108 compliant or street legal for headlight use. International regulations vary.

What's Included: Two H13 White SL2 Pro LED bulbs.

Fitment: Compatible with vehicles designed for H13 bulb applications. Confirm the required bulb size, housing clearance, and local lighting regulations before purchase.
