Hmmmm, rear light could be micro switches on either handlebar or rear assembly stuck open or possibly a wiring fault?
Back firing - first suspects for me would be around the gas tank, trapped fuel line or trapped/blocked vent line on top of the tank, Blocked filters, fuel pump, bad carb sync, the list goes on and on after that I'm afraid....
Good luck
