Help with my brake light issue
Your bike has two brake light switches, front and rear. To identify your brake light problem, disconnect one switch at a time, to see if the brighter bulb filament goes out. Reconnect the first one, then disconnect the other. If the filament goes out, the switch you just disconnected is at fault.
As for the dim flasher, that sounds like a possible damaged wire, causing a ground. However swap the bulbs from one side to the other, to check it isn't one of them. If the problem remains on the same side, the bulbs are OK. Inspect the wiring to that light unit to identify a break in insulation.
