Video Overview
Application Notice: 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. Legal for off-road use. International legality varies by country. This regulation applies to all LED bulb brands.
Optimized Optical Focus
High lumen numbers mean nothing if the light source is out of focus inside your housing. The SL2 is engineered to emit light from the same location as the original halogen filament, preserving the factory beam pattern and hotspot. The result is a functional beam with a stronger hotspot for added distance and visibility — not just more glare.
Fanless, Compact Design
No oversized cooling straps. No noisy fans. The SL2 uses a copper-core circuit board and thermally-optimized full-metal housing with an integrated heatsink to keep running at maximum potential. At 14 watts, it delivers plenty of output in a compact package that's not much bigger than a standard halogen bulb. The internal driver means nothing to tuck away — just remove the old bulb and plug in the SL2.
White or Yellow
The SL2 is available in two color options: 6000K cool white for a modern appearance that matches most OEM lighting, or selective yellow for high contrast in inclement weather. Both use multi-die automotive-grade LED emitters.
Built for Reliability
Every component — from custom wiring to exclusive aluminum castings to the integrated driver with built-in circuit protection — was designed with longevity in mind. The SL2 has been tested through dozens of thermal cycles from -40°C to 85°C and is compatible up to 30V. It's backed by a limited lifetime warranty.
