Osram LEDriving SL W21W cool white LED bulb with W3x16d base

The Osram LEDriving SL W21W cool white LED bulb is the perfect choice for any vehicle owner looking to replace traditional W21W bulbs with modern, reliable, and long-lasting LED technology.
This LED retrofit solution features next-generation light sources that consume up to 80% less energy than conventional bulbs, while still delivering impressive lighting performance — providing 145 lumens of brightness, ideal for use as signal or indicator lights. With a 6000 Kelvin color temperature, it emits a modern cool-white light that is not only stylish but also highly visible during both day and night driving. One of the main advantages of LED lighting is its instant illumination, which allows traffic behind to react more quickly to vehicle movements — whether braking or changing direction.
Thanks to the W3x16d base, the bulb is easy and quick to install in any W21W-compatible socket, requiring no modifications or special tools. Part of the Osram LEDriving SL series, this bulb is made from high-quality materials, ensuring a long service life of up to 4000 hours and stable performance. This significantly reduces maintenance needs and offers a more cost-effective long-term solution.
