After a bump from behind by a less-than-attentive pickup driver, I bought AdMore lights for my Givi V47. They operate as run/turn/brake lights with a few options: "ping" mode, disable run function (so turn and brake only.) The kit is working well.
An alternative I have seen is to use an LIN3 from Whelen Engineering in place of the rear reflector. Hit the stop pedal and even God's own self will know you are electing to whoa up.
Being slow doesn't make a boring bike. I had a R1 which I thought was boring. Boring is a bike that doesn't speak to you. If you like what your bike is saying let it's voice take you to far flung places. - Vertical C
