Question: " + How Many pins does a Tri-Level, Tri-Color LED have and how do I control the color output? I want a Tri-Level, Tri-Color LED with each LED being able to display three different colors: Red, Green, Yellow (Amber). How many pins are required to control each LED of this type?
Answer: The only Tri-Level, Right Angle PCB LED in Tri-Color is 2 Leaded for each LED type. You get Red color in one direction of power input, Green color in reverse power input and Amber-Yellow when the LED is powered from both sides like driving with AC. For better 3rd Color mix, we make High Diffusion Bi-Color/Tri-Color LED for this package. For a high quality 3rd color, you have to adjust power up or down for each color to get the color of your choice.
