Horns and lighters are heavy current draws. Usually they are unfused and not run thru the ign switch. Those diagrams I looked at have the horn relay fed directly from a constant hot wire. Some models did run thru the ammeter, others not.

Didn't find a spec for your model but the mid 30s and onward years that did provide specs list on average 22-25 amps with two horns and 33-36 with three. With that logic a single horn is drawing around 12 or so amps so if you are going to fuse or switch it on or off I would plan accordingly. Lighter elements have a fairly low resistance when they connect up and probably draw that much if not more.
