On my list of things to do:
1. Install a Signal Dynamics lighting module for the rear taillights.
If not familiar, Signal Dynamics is a Florida based company that specializes in various types of modules. These can modulate the headlight (a headlight modulator, which I also have (yes, legal in all 50 states)) blink the brake lights in a certain way, or even combine your turn signals into running lights. I have used these before over the years, including the classic Back Off Module on my wife's EX500, but nothing on the Hayabusa. These basic modules are all very inexpensive, around $40 (about 2 pizzas ).
There are several to choose from here:
I have used the basic one, as mentioned, and also a few years ago a Priority Lites Module (which someone somewhere likely still sells) that turns the turn signals into running lights. I had tried it on the Hayabusa years ago, but kept melting the turn signals. Weren't designed to be on all the time. Stock ones would likely do fine.
After re-reading through the descriptions and how they're different, I chose the Wig Wag module. Which for any bikes that have two tail lamps, it alternately blinks the taillamps under braking making them very noticible! That's the goal. This one also works with LED's which are becoming increasingly common. Not sure how LED's are different than bulbs - but I have them.
If you have two tail lamps like I do, the Wig Wag Module will work great!
