My brake light stopped working, both front and rear don't work. I've confirmed it's not stuck on instead of not working. I've tried three different bulbs. The socket looks fine, no corrosion, bulb sits in it fine. I bought the bike used and the brake light would strobe flash first before going solid so I figured it has an aftermarket addition like Back Off or something similar but I can't find one anywhere. So I figure I'm going to have to get a meter and start testing but I want to know where to look. Where do the front and rear brake wires converge and how? BTW it had a weird looking bulb in there, not your typical 1157 and not led.
