Thank you for Light show 😊 just got a Centurion ( Whelen) light bar from a friend its from era of Whelen when they made rotating bulbs with mirrors. What neat about it is you can just rotate the end rotation light with one wire. And the other rotation light with another wire. Therw is a third wire for flashers in bottom of bar. The middle of bar is clear doom with just mirrors inside. The two outside lens are red. The bottom flashers have a mix of amber and Red squar flashing bulbs along whole front of this very unique Whelen flashing light bar.
