Looking for a Federal Signal, Signal Master 1. I need one with Red LED's and one with Amber LED's. Both must be with the black PCB board. Federal made two types, one with the lighter "grey" PCB board and one with the "black" PCB board. I believe the black one is the first generation. I need the type on the left.
