Need some indicators? We are big fans of these diffused LEDs. They are really bright so they can be seen in daytime, and from any angle. They go easily into a breadboard and will add that extra zing to your project.
If you need some help using LEDs, please read Adafruit's "Introduction to using LEDs" tutorial for any electronics project.
The specifications vary by color:
