Multiple Use: Ultra bright 3V purple LED light diodes are perfect for a wide range of DIY lighting projects, science circuit experiments, model making, custom indicator lights, and creative home decoration, offering versatile illumination for hobbyists and teachers.

What You Can Get: 20 Pcs pre-wired and pre-soldered emitting diodes. Color: Mixed; Dimension: 200 mm/ 8" precision (±1%); Each DIP 3mm LED features current-limiting resistor, ready for immediate use straight from the box.

Material & Design: Engineered for reliability, each LED diode emits a vibrant light with low heat output and high efficiency. Clearly identified polarity (colored wire for anode, black for cathode) and robust pre-soldered connections that won't come apart easily.

Easy to Use: Simply connect the prepared wires to your power source, ensuring correct polarity matching. The in-built resistor is already calculated and attached, eliminating complex calculations, extra soldering, and preventing overload for a secure, plug-and-play experience.

Wide Application: Suitable for building custom electronic projects, creating decorative accents, designing educational science kits, replacing miniature indicator lights, or enhancing RC models. These pre-soldered LED lights are essential tools for both beginners and advanced makers in their DIY items.
