It ain't easy being me!
Some years ago (10?) I put a module on my Gold Wing in the cowl under the trunk that every time the brake circuit is activated my rear brake lights flash 3 times quickly followed by 3 times slowly followed by a steady light ( the fast and slow might be reverse, I can’t remember). It reactivates the sequence every time the circuit is interrupted and reapplied like taking your foot off or your right hand. Still leave space in front to get out of the from the texter when I stop but it wasn’t a difficult or expensive install.
