if your front lights stay on all the time they probably have a 2 filament bulb and an extra wire coming from the indicator like US models do, all you have to do is disconnect the wire. Having never seen MC28 never mind working on it I can't be sure of colors but every Honda usually has Blue and Green wires for indicators, and I believe orange would be the "parking lights" as they call it here. on some bikes each wire is plugged in individually using round bullet connectors and if that is the case you can just unplug the orange wire.
I can do more if you had posted pictures of indicator lights, wires and connectors, it's a simple task if you know what you doing
