Compact, reliable 3 mm white LED pack designed for straightforward installation and consistent illumination. Key benefits Bright, steady light: 3 mm LED with a clear white lens delivers stable illumination for indicators and small lighting tasks. Simple hookup: Red wire = positive, black wire = negative. Pre-wired LEDs save assembly time and reduce wiring errors. Plug-and-play protection: Built-in resistor allows safe operation on DC 3–5 V systems without adding external resistors. Low power draw: Energy-saving design keeps current use minimal while maintaining consistent output. Flexible reach: Each LED includes a 20 cm flexible wire for easy routing in tight or hard-to-reach locations. Ready for multiple projects: Package contains 20 pieces so you have spares and enough parts for small production runs or group projects. Practical applications DIY electronics and prototyping: Ideal for breadboards, hobby microcontroller projects and low-voltage indicator circuits that use 3–5 V supplies. Control panels and status indicators: Use as clear, reliable indicator lights on custom enclosures, switches, or instrument panels. Scale models and decorative lighting: Small footprint and clear lens fit into model builds, signage, or accent lighting where discreet illumination is needed. Technical details LED size: 3 mm Lens: White, clear Quantity: 20 pieces included Drive voltage: DC 3–5 V Wiring: 20 cm long flexible wire per LED; red = positive, black = negative Built-in resistor: Yes (no external resistor required for 3–5 V operation) Performance: Low power consumption, stable output What you get Twenty pre-wired 3 mm white LEDs with 20 cm leads, ready to install in 3–5 V projects for quick, reliable indication and lighting.
