I tried playing with the EPA but not sure what else to try.
What channel do you have them plugged into? Are you using any mixes?
To dim an LED you have to pulse it rapidly, simply lowering the voltage won't make them dim the way a filament bulb does, so it sounds like it has something to do with the channel's characteristics. You mentioned the switch you're using as "(THR)", if you have it plugged into the throttle channel that might explain it. That's how the ESC slows a brushless motor, by pulsing it slower. Try connecting the lights to another channel, like the gear (5) channel.
