Includes Commander, OBD cable, and a pry tool. Installed at the rear OBD port under the rear vent on Model 3/Y built between late 2020 and early 2025 (without Model 3 Highland). Tesla Model 3's refreshed pulse high beam is an upgraded vehicle lighting system designed to enhance visibility and safety during nighttime driving. The pulse high beam generates a brighter and more focused beam of light to illuminate the road further ahead, allowing the driver to see the road. With Adaptive Headlights, the headlights can adjust their beam pattern to better illuminate curves and bends in the road as you're driving. It's a cool new technology that promises to make nighttime driving a lot more convenient and safe. Update: We now have our first video of the new adaptive high beams in action. The new feature works by selectively dimming.
