This "LED Party Pack" contains 20 common T-1 3/4 LEDs:
- Five Green T-1 3/4 LEDs
- Five Yellow T-1 3/4 LEDs
- Five Red T-1 3/4 LEDs
- Five bi-color Red/Green T-1 3/4 LEDs
The bi-color LEDs have two pins; current flow determines whether they light up red or green. They make great High/Low line status indicators.
This is a nice pack to replenish your supply, either for a classroom or for your own prototyping workstation. If all you really need are plain old red LEDs, we have an inexpensive Red 10-pack.
