They are 2v 20mA LEDs. The third photo has the resister info. Some sites have "12v" LEDs but seem to have the resistor built into the bulb somehow according to the diagrams and still output 20mA so I'm guessing they end up being roughly the same. But I could be reading or understanding it incorrectly.
