A quick check online, that light means one of the lights on the bike is malfunctioning. I determine the rear brake light is on bright even when no brake lever/pedal is pressed. More digging. I check the DTC codes, I have a B2223, which indicates the rear brake has stayed on for more than 2 minutes.

Dug into the factory service manual next, ended up at the section called "Running Lamp Diagnostics." Find the rear brake light switch by the rear master cylinder, remove a green wire - now brake light goes out. Survey says: Replace the rear brake light switch. It's about $8. Tomorrow I'll see if I can find one locally.

I literally just posted a YouTube video last week with my 30,000 mile review, and I thought "wouldn't it by ironic if something broke next week. LOL. Well, these are the kinds of problems I can deal with.

Here's my vid if anyone's interested...

I would suggest checking the events page at your local dealers and maybe even sign up for e-mails from them so you can be notified when a demo event is coming.

There are a couple things it could be, easiest thing is the brake light switch. If that doesn't work you may need to check the plunger coming out of the master cylinder. Has your brake fluid been flushed every few years? I had never flushed mine and it ended up getting so gunked up the plunger wasn't fully retracting out of the master cylinder. When that plunger comes out as you let off the brake lever it pushes in the brake switch and turns off the brake light. I ended up rebuilding the master cylinder and cleaning all that gunk out, flushed the brake system. All good to go using the factory brake switch still.

Will the rear brake still work? Possibly, but not as well as it could. Mine was going down further than it used to. I bled mine until there was no air. Since it was wet out, I took it down the road and engaged the rear ABS about 10-15 times. Bled again and more air came out. Now the pedal was nice and firm. I think it's all good now.

Thanks for the tips. I was fortunate with this one, easy to diag, the dealer had the parts, and the install was also easy.
