P21 LED refers to a specific type of LED bulb that is commonly used in automotive lighting applications, particularly for brake lights and turn signals. These bulbs are designed to replace traditional incandescent bulbs, offering improved brightness, power efficiency, and longevity.

P21 LED bulbs typically use a series of small, high-intensity LEDs mounted on a central board. They come in a range of sizes and shapes to fit various types of light fixtures and housings. Some P21 LED bulbs also incorporate advanced features like dimming, flashing, and color changing.

Compared to traditional incandescent bulbs, P21 LED bulbs offer several advantages. They use significantly less power, which can help to improve fuel efficiency in vehicles. They also have a longer lifespan, lasting up to 25 times longer than traditional bulbs. Additionally, they offer a brighter, more focused light output, which can improve visibility and safety on the road.
