Angrong Universal 566 P21/4W BAZ15d LED Sidelight Tail Light DRL, 2 Pack

Meet the Angrong Universal 566 P21/4W BAZ15d LED Sidelight Tail Light DRL — a reliable, high-performance lighting solution designed to replace 566 (P21/4W) bayonet bulbs. Sold as a 2-pack, these LED bulbs are built for 12V systems and deliver a bright 6000K xenon white glow for Turn Signals, Sidelights, Tail/Brake lights, Rear Fog, and DRL applications. Each bulb packs 15 high-power 2835 SMD LEDs, providing roughly 800 lumens of crisp, long-lasting light that helps other drivers see you clearly in daytime and night driving.

With a compact profile of about 55mm in length and 18mm in width, these bulbs install easily into the OEM BAY15d socket. Their plug-and-play design means quick Start-Up times and minimal fuss during installation. The 12V operation and modern LED technology offer energy efficiency and longer life compared with traditional bulbs, making them a practical upgrade for both older vehicles and newer European models that rely on CAN Bus systems.

These bulbs are especially effective as daytime running lights (DRL) or for rear lighting in both urban and highway driving environments. The 6000K xenon white color provides high visibility without harsh glare, helping to improve safety for you and other road users. Note that some vehicles with CAN Bus wiring may display warnings or hyper-flash; if this occurs, adding a Load Resistor in the circuit is a common and effective solution. Always verify compatibility with your vehicle’s electrical system before final installation.

Benefits & Tips

• Bright, clean 6000K xenon white output improves daytime visibility for turn signals, sidelights, and brake lights.
• Low power consumption (about 15W per bulb) with longer life than traditional halogen bulbs, reducing maintenance and replacement frequency.
• CAN Bus compatibility for many modern European cars; if hyper-flash or error messages appear, consider adding a Load Resistor as needed.
