I recently noticed that one of my recent bars was not the normal basic Excalibur I come across. It has strobes on the outer part. Only the back on one side works. I powered up 2 steady lights on the inner area with a loud steady horn type sound. The arrow stick does not work and lots of other wires do mostly nothing. The bulbs look fine. I am not familiar with this type of bar. I can find little info. I did find one in parts on a website but it looked like a deluxe version with more strobes. Any info anyone has would be helpful to get it working.
