I have a Whelen Advantedge 4000 that is halogen/Rotator/Rotator/Scene light/Halogen/Scene light/Rotator/Rotator/Halogen. It goes on the back of a ambulance I am looking to upgrade to all LED we have been having problems with the rotators freezing up. Has anyone done it yet if so can i get some help. The halogens im not really to worried about just making up the bracket to hold a 700 or 2 400s is going to me the hard part.
