OK, so I am trying to fix this opto board and it looks like these Infrared LEDs are running on 12v. The only problem is that I can't find a 12v infrared LED anywhere online. The highest I have seen is 1.5v. There are 270 ohm 2watt resistors before these LEDs, does that drop the amperage enough so that 12v won't blow them out??
