Just heard back from Vectolabs, makers of Vololights and Volomod. Unfortunately, the first won't work on the F3, and the second needs significant modification. Here is the reply:
"Hello Roger,
Thank you for your interest in our products!
well, the vololights is not an option for your bike, we had some customers found out that the swing arm vibrates way to much causing false positives, making the unit flash constantly.
You could use the volomod but your bike is on Canbus system, and because of this we cant insert any signal into your stock (OEM) lights, so you would need to find a 12V switched source to power up the unit and get some LEDs to use as output instead of your turn signals. Some of our customers get LEDs from Custom dynamics and attach them to our volomod. but unfortunately our volomod is out of stock.
Do you want me to let you know once we restock?
Regards!"
Have previously been advised that gear brake is not compatible with the F3.
So, still looking for something that works on the F3.
