PBLs 3 LED package is one of the main LEDs that go in my machines. I have gone through 10's of thousands of them with maybe 20 DOA or failed. They are very reliable. I also use a couple of different packages from CoinTaker. If you want to see what they look like in a machine, you can view machines on my website at eapinball.com. There are over 100 machines on the site with them installed.
