Just replace it, it's not expensive.
Locate the relay/fuse center under the hood, remove relay/fuse center cover, pull out the starter relay and replace it with a new one. It is seldom the relay is at fault.
On the passenger side you must remove the air filter box. You will need a small arm to reach the light but it is possible. One of the reasons I will never buy another one. On the divers side it is much easier. Remove the air valve and you can reach the light. Good luck the first time. It is not an easy job. the manufacture has designed this to make you want to take it to the dealer to have this done.
There are two circuits at the multifunction switch lever. One is for the flash to pass. The other is the normal high/low beam circuit. The two most likely problems are a lack of power from the headlight switch, or a broken wire at the multifunction switch connector. The second is prone to happening if you tilt the wheel frequently.
Open the hood to the engine compartment. Take hold of the headlight connector. Push the connector in and turn at the same time. The lightbulb will come out. Reverse the process to install the new lightbulb.
