Very happy to share with everyone that the tail tidy had nothing to do with the rear brake light issue! Turns out that behind the rear set the spring/connection for the brake light switch was loosened; tightening the spring by shortening the plastic bolt did the trick! I read something about this on another post last night researching the issue (and realized I may have caused this when I installed the Yoshi exhaust couple months ago and just never noticed the rear brake light going bad). Either way, it is up and running!
