Pull the turn/backup fuse, step on the brake, does the backup lamp still lite? If so, the lamp is getting voltage from another source. Possibly from lamp ground wire. If another component has no ground or very poor, the voltage will seek ground. May go through back up lamp, the voltage is coming through back up lamp ground. You could take reverse lamp ground loose, just to see if lamp goes out. Just for testing. If weird things happen with lights, it's usually a poor ground, somewhere. Maybe a poor ground for brakes?
