Vehicle Fitment

Universal - Fits any vehicle using an H3 bulb socket (commonly found in fog lights and auxiliary forward lighting applications)

Fitment Notes

Direct plug-and-play replacement for factory H3 bulbs - uses the same H3 socket with no adapters or modifications required.
Sold as a pair (2 bulbs).
Compatible with operating voltages from 9V to 30V - suitable for 12V and 24V electrical systems.
IMPORTANT - Legal Notice: These LED bulbs are legal in the USA for fog light use only. They are NOT compliant with DOT / FMVSS108 and are not street legal for use in headlight housings in the United States. This restriction applies to all LED bulbs from all brands - it is not unique to Diode Dynamics. Legal for off-road use in ATV, snowmobile, and off-road racing applications. International legality varies by country.
Some vehicles may require a decoder module to prevent bulb-out warnings or hyperflash - verify with Diode Dynamics' vehicle-specific fitment guides before ordering.

Features

Optimized optical focus - the SL2's LED chip is engineered to emit light from the same position as the original H3 filament, preserving the fog light housing's designed beam pattern and focused hotspot without adding glare. This is a critical and often-overlooked difference from budget LED bulbs that put light in the wrong place.
Selective Yellow color provides the wavelength characteristics preferred for fog light use - yellow light cuts through fog, rain, and snow better than white light and reduces backscatter toward the driver.
Fanless design eliminates the primary failure point of traditional LED conversion bulbs - no fan means no fan bearing failure, no noise, and no additional airflow requirement in the housing.
14 watts per bulb with copper-core circuit board, thermal phase-change interface material, and thermally-modeled aluminum casting with integrated heatsink - provides effective heat dissipation without a fan by engineering the thermal path correctly.
Integrated driver - no external driver box, dangling wires, or external components required. The driver is built into the compact bulb body.
Automotive-grade LEDs with built-in circuit protection and transient suppression for long-term reliability across harsh automotive electrical environments.
Tested through repeated thermal cycles from -40°C to 85°C (-40°F to 185°F) - rated for extreme climate use.
Designed and engineered in the USA by Diode Dynamics.
Backed by Diode Dynamics' Limited Lifetime warranty.

Product Description

The Diode Dynamics DD0472P is a pair of H3 SL2 LED bulbs in Selective Yellow - a premium fanless LED fog light upgrade engineered for any vehicle using an H3 bulb socket. The SL2 was developed as a successor to Diode Dynamics' popular SLF bulb, featuring a more compact design, integrated driver, and improved thermal management without the use of a cooling fan. At 14 watts per bulb with a copper-core circuit board and thermally-modeled aluminum heatsink casting, the SL2 manages heat effectively through engineering rather than airflow - eliminating the primary failure point of fan-based LED conversion bulbs.

The selective yellow color is the preferred choice for fog light use, as yellow wavelengths scatter less in fog, rain, and snow than white light, reducing backscatter toward the driver and improving contrast on the road surface. The SL2's LED chip is precisely positioned to emit light from the same optical center as the original H3 filament, preserving the fog light housing's designed beam pattern - a detail that separates optically-correct LED replacements from budget alternatives that simply produce more raw lumens in an unfocused pattern. Installation is fully plug-and-play for H3 sockets. In the USA, these bulbs are legal for fog light use only and are not DOT/FMVSS108 compliant for street headlight use.
