Description
These 3mm Bi Colour LEDs combine red and yellow outputs in a single compact package with a diffused lens for smooth, wide angle light distribution.
Featuring a common cathode 3 pin layout, these LEDs are ideal for status indicators, panel lights, prototyping, and electronic visual displays.
Switch between red, yellow, or alternate both for visual feedback depending on polarity and input configuration.
Compatible with breadboards, Arduino, Raspberry Pi and other electronics platforms.
