[QUOTE="wfooshee, post: 1293677, member: 6354"] Basically, the brake lights don't have to be turned on when the brakes are applied, they have to be turned off when the brakes are [I]not[/I] applied. There's a brown wire at the brake light relay. make sure there is 12 volts on that wire when the key is on. Also at the relay, the Green/Yellow wire should be 12 volts with key on and front brake lever not pulled. Brown/Black wire should be ground with rear brake not pressed. Relay should click and Yellow/Green wire go to 12 volts with key on and either brake being operated. If that doesn't happen but everything else is right, then it looks like it's the relay. Thing is, any of these failures should leave the brake lights ON, not render them non-functional. So..... are the bulbs good? If you've been riding around with constant brake lights, maybe the brake filament is blown in both bulbs by now. (BTW, difference between Green/Yellow and Yellow/Green if it's not apparent: Green/Yellow is green with yellow stripe, Yellow/Green is yellow with green stripe. Just in case that was fuzzy.) [/QUOTE]
