Building on the success of the original LEDriving series, this upgraded bulb delivers improved brightness and reliability in a durable, stylish design. The LEDriving SL Advance produces a bright white, red, or yellow light, ideal for drivers seeking improved visibility and modern styling. Unlike basic LED bulbs that create a dotted or uneven beam pattern, the LEDriving SL Advance provides a wide, uniform light output for superior clarity and road presence. Engineered by OSRAMs automotive lighting experts, this bulb uses high-quality components for optimal performance and longevity. It offers a cool-white, red, or amber light output with a long service life of up to 25,000 hours, backed by a 2-year manufacturer warranty. The energy-efficient, low-wattage design helps reduce electrical load while delivering strong illumination. Built for durability, the LEDriving SL Advance resists damage from vibration, shock, moisture, and extreme temperatures. Its plug-and-play installation ensures quick and easy replacement without modifications. For vehicles with sensitive electronics, a CANbus decoder may be required to prevent flickering or error messages.
