Safe Low-Voltage Design: The LEDs utilize a 12V input voltage and a low 20mA operating current, consuming only 0.06W, ensuring safe operation. Accuracy Signal Indication: The narrow 30° beam angle focuses light for clear and eye-catching indication, making it ideal for signaling or status indication in applications such as remote-controlled vehicles, boats, and industrial equipment. Easy Installation: The red and black two-color wires distinguish between positive and negative poles, and the numbered sheaths and 20cm long leads allow for flexible wiring, allowing even novice users to quickly and accurately connect wires. Durable and Compact Construction: The 3mm diameter LEDs are compact and lightweight, and the copper material enhances conductivity and durability, making them suitable for confined spaces in cars, toys, and cameras. Versatile Application: Suitable for a wide range of applications, including home, commercial (schools/churches/auditoriums), party decorations, and industrial applications, whether providing functional guidance or creating a vibrant atmosphere.
