Cleaning Traffic

I have one of each of these lightbars and both have two cables that come out of them. One is the regular power cable (red and Black) and the other a very thin cable with just a blue and gray wire inside of the shield. I am told this requires a certain type of controller. I am not familiar, as these are older bars. Looking to buy (or trade for something) a controller that will test these. Thanks in advance!
