I noticed recently that my brake light doesn't come on when I use the rear brake alone, only when I also use the front. Obviously this is not ideal in all conditions. I checked the connector from the brake pedal next to the battery, and the connections appeared to be fine (although I haven't hit it with any kind of electrical contact cleaner yet). Where else should I be looking?
I also recently noticed that my rear right turn signal has stopped working a couple times, but is otherwise fine, and doesn't seem to be predictable in any way. Usually it works fine, but on two rides, I suddenly started getting the double-time flash on the dashboard indicator, with confirmation from the friend I was riding with one of those times that the light wasn't working.
