Federal signal Message board MB1 blue UNTESTED USED

Used condition removed from a decommissioned police vehicle. WE DID NOT RECEIVE ANY CONTROLLERS FOR THESE AND HAVE ABSOLUTELY NO WAY TO TEST THIS UNIT. NEW CONTROL HEADS RUN ABOUT $850 NEW EACH. THE PLUG IS ALSO MISSING. Selling AS IS to someone who already has the controller or needs to replace a bad Message board. Absolutely no testing was conducted and no guarantee is offered on operational condition. You will receive the exact pictured unit. Was interior mounted and in very good cosmetic shape with only light scratches, scuffs, and grime. Has two mounting brackets. This is made up of all blue diodes and designed to be programmed to display various messages and traffic advisor arrow via Federal Signals MP1 control head.
