The SM-309 and SM-310 are professional-grade auxiliary spot lights designed for motorcycles, scooters, and off-road vehicles. While the SM-309 (G15) features a compact Single Lens design for focused 20W illumination, the SM-310 (G16) utilizes a Dual Lens architecture to deliver a massive 40W of light. Engineered with precision optics, these spot lights provide a powerful "laser-beam" throw that penetrates through darkness, fog, and rain, significantly enhancing rider safety and road visibility.
