SL1 H9 LED High Beam Headlight Pair

Designed to replace factory H9 bulbs, this pair of LED headlights offers enhanced visibility with an optically correct output and a focused beam pattern, ensuring you have a clear hotspot and wide spread of light without excessive glare. They are built to meet or exceed OEM lighting standards, providing a reliable and high-performance solution. Featuring a compact, patented design, the SL1 LED bulbs are engineered for easy installation, fitting even in sealed headlamps where other LEDs may not. The bulbs utilize advanced cooling technology, including a copper core board, thermal phase-change material, and a zinc heatsink paired with a microfan, to efficiently dissipate heat and maintain optimal performance over time. Materials like a copper PCB, PP-TD30 base, and zinc heatsink contribute to their durability. This ensures a functional low beam pattern on the road, preserving the crucial hotspot for distance visibility while avoiding added glare. The SL1 LED also incorporates a boost-mode electrical circuit and current-monitoring circuitry to mimic halogen bulb characteristics, minimizing the need for CAN-BUS adapters and ensuring long life in automotive circuits. They are tested to perform through extreme temperature cycles, from -40°C to 85°C, and come with a 3-year replacement limited warranty. The bulbs are compatible with 2016+ Toyota Tacoma models.
