Light bulb issues: Check the light bulbs to ensure that they are not burnt out. If they are, replace them with bulbs of the correct wattage and type.
Faulty wiring: Check the wiring for any loose connections or damage. Check for frayed or broken wires, particularly in areas near the handlebars and front end of the motorcycle.
Switch issues: Check the headlight switch to ensure it is functioning properly. Try turning it on and off several times to see if the headlights will come on.
Relay issues: If the headlights are not working, the headlight relay may be faulty. Check the relay and replace it if necessary.
