Have you done any thing to the bike?
Start checking fuses and relays. Check bulbs too.
If there good pull the seat look for pinched wires make sure your battery cables are tight.
Being a 07 your battery might be going bad. Put a full charge in it and have a battery shop check its strength.
Pull head light and check wires inside there
