SL1 H11 LED Fog Light Bulbs w/ Anti-Flicker

This pair of H11 bulbs provides a cool white light with a 6000K color temperature, designed to improve visibility. The SL1 bulbs are engineered with advanced optical design software to ensure a focused beam pattern and hotspot, mimicking the performance of original halogen bulbs while avoiding added glare. They are designed for a perfect H11 fitment with no modification required, fitting inside sealed housings and behind dust caps due to their compact size. Included with your order are anti-flicker modules, essential for vehicles with CANBUS electrical systems. These modules condition factory power signals, smoothing out flickering and preventing the "bulb-out" warnings that can occur with LED power draws by replicating halogen bulb consumption. Diode Dynamics has rigorously tested these bulbs in factory lamps using specialized equipment to map the entire beam pattern and validate optical performance. The cooling system integrates a direct-solder copper core board, thermal phase-change material, and a zinc casting with a microfan for efficient heat dissipation, ensuring long-term reliability and consistent output. The SL1 LEDs are backed by a three-year warranty and are engineered and assembled in the USA.
