The term "2 Leg Bicolor Tricolor RG, RB, RGB LED Through Hole" refers to LEDs with specific color combinations and electrical characteristics:
Bicolor LEDs: These LEDs have two different colors, and they typically have two legs (pins) for each color. For example:
Tricolor RGB LED: This LED combines three primary colors (Red, Green, Blue) in a single package, typically with four legs (pins):
Through Hole: This indicates that the LED is designed to be soldered onto a circuit board through holes in the board, as opposed to surface-mount LEDs which are soldered directly onto the surface of the board.
