Hey MR, did the Magic Strobe kit for the rear brake also make the "3rd" brake light on the tour pack flash? That's a mod I'm looking to do on mine.
No, it does not do that by the default wiring, but I am sure one could make it so with a little effort in changing up some connectors.
My wife drove the cage behind me for a couple of hundred miles a month or so ago, and some of it was in POURING rain...she said the LED brake light and strobe were highly visible from any distance within sight of the rear of my bike. She remarked that a person would have to be blind not to see it. All that, of course, is dependent on the cage driver paying attention to what they are doing and not texting, etc....in that case, I don't know that any amount of lighting would help.
