there are some aftermarket, universal controls that are not identicle to the original CB550 part, but will give you the headlight switch, start button, kill switch, turn signals, horn, etc... so maybe if you cant find a direct replacement you could wire an aftermarket universal fit part to it, this is what i intend to do with mine... some aftermarket options even give you the option of a high/low/off switch for your headlights so you dont have to wire an on/off switch elsewhere
