Reply #1....... Hey! Welcome aboard. Tell us a bit about you and your bike, doesn't have to be too detailed but a little sumpin'.
Reply #2........Bulbs burn out.
Reply #3........Welcome aboard! Sometimes the bulbs do burn out and have to be replaced. Not sure of your experience or how long you've had the bike but to access the speedo bulb you'll have to lift the speedo out of its chrome bucket, access from below.
The headlamp comes on when you tickle the ignition by either starting the bike or attempting to start the bike.....one of those newer model improvements there that most could do without. If the lamp doesn't come on it could be the bulb too, I would check with a known good headlamp or ohm between the three plug ins......I forget how that reads but would compare it to a known good lamp.......buy a spare. They don't cost anything to feed them once purchased.
