I can't even use it. Read the manual, tried experimenting with the remote on my own. It goes between an extremely loud, piercing, irritating "anti-theft" sound at the slightest touch, and the blinking on one side or the other for turns. Can't get it to just turn on and stay on as a normal brake light, and due to the shrieking noise at the lightest touch that is extremely hard to stop, I can't put it on my bike at all. Imagine that sound out in public all the time. And I'd have to keep it on a side blinker light that would look like I'm always turning.
