True, the isolator will reduce electrical loads on the bike circuits. However, I feel the best reason to use one is to protect the bike wiring. If the trailer develops a short circuit then the fuse (located close to the battery) for the isolator circuit will protect the trailer and isolator wires. If this fuse opens, you will still have all the bike's normal lighting intact.
