The five clear LEDs are actually two colours: a perfect time to whip out the LIGEMDIO project for some LED testing:
Note that the PT333-3C Phototransistor uses a familiar 5mm LED packaging, but the collector/emitter pins are the reverse of what you might intuit. The short leg and flat edge are actually the collector and is connected to the positive supply side.
