On the brakes, first +1 to what chak said on replacing fluid.
As it's a closed system you only need to get into proper bleeding when there's air trapped or if you replace or rebuild the caliper. It's not the end of the world, but it changes the job from pouring fluid in a reservoir while fiddling with a spanner and a leaver into something more involved.
Both my Derbi (Piaggio brand) and my Triumph had the rear brake light controlled from the actuation of the foot pedal hitting a switch. It was unconnected to the brake fluid system.
