Welcome to the forum from North Carolina. Happy you decided to join us. You did not mention if your bike was a Standard or a Classic. So went with Standard. You have a strange issue. Did this issue arise after some maintenance or modification was done? Does the light go out when you pull in the clutch or when you put the bike in gear? The switch that is involved when putting the bike in gear is the neutral safety switch. This switch is connected to the starter circuit relay and the headlight relay in the relay box. Also in this system is the headlight, taillight, high beam indicator, dimmer switch, starter lockout switch (clutch switch), neutral indicator light, engine stop switch, and some other components. Start with buying a spray electrical cleaner/lubricant and spray the clutch, neutral, kill, starter, dimmer, and side stand switches. Here is a link to the manual wiring diagram. If you bike is a Classic use the second link. If anything is unclear or if spraying the switches had no effect, please post back and we will help you. Thanks again for joining the forum. Be well and Ride Safely.
