Not that you'd be using MTH signal heads...but wouldn't it be dandy if you could plug their 4-wire cable right into your board. cool Not sure if they use common-anode or common-cathode, not sure exactly what kind of connector they use, not clear how their wire-color-key maps to the LED colors, etc..
