Description
10 x 3mm Bi-Colour LED – Red & Green – Diffused Lens – Common Cathode – 3-Pin
These 3mm Bi-Colour LEDs combine red and green light outputs in a compact, through-hole package with a soft diffused lens for a wide 120° viewing angle.
With a common cathode configuration, they’re perfect for creating dual-colour indicators, status lights, or blending to amber when both colours are lit simultaneously.
Ideal for use in Arduino, Raspberry Pi, and other DIY electronics projects.
