Code 3 led traffic advisor ARROWSTIK BLUE AMBER USED

Used condition. Tested and fully working. Removed out of a decommissioned police vehicle. This lightbar seems to be the first Gen DUO technology as each module in this bar is alternating blue amber. Can flash all 8 modules in blue with the built in flasher and have the same 8 modules do amber steady and would require a code 3 traffic advisor controller to do ta or flash. It is a very interesting bar and have never seen one before. Will receive the pictured bar. 
 Unit is 40 inches long and includes around 3ft of wire harness. Normal cosmetic wear including very light lense yellowing scratches and scuffs is present.
