Review on FANCYWING Accessory Backpack Direction Indicator by David Ocampo

This is the most reliable turn signal system I have found for cycling. I turned down some bike-mounted options because they lacked reliability, couldn't hold a charge or pair with the included controller, or had a controller that couldn't be operated with full gloves. Though it's meant to be attached to a backpack, mine was strapped to Fox titanium body armor. It's detachable so I can still wash the jacket if it stinks, but it has enough straps to keep it in place even if a spill occurs. it holds a charge for weeks or more. It features an easy-to-access full USB connector (male) that slides out of the zipped compartment. I ended up using a cord with an outlet for charging, but that's not necessary if you want to get it close to an outlet (which is outdated to me, considering it's body armor mounted). The controller is the most reliable/efficient design I've seen in a bike turn signal. The buttons are raised, easy to see and feel. I can reliably find the right button on the first try without looking. You get an instant flashing light on the controller, but that light doesn't stay on all the time. On the other hand, this means that the rider cannot be sure which signal is currently being displayed (but unfortunately this is typical for most bikes). Turn Signal Systems.) A workaround is to develop the habit of pushing forward or into neutral when in doubt. As with most comparable products, your signal will persist until you adjust it to a different setting (yes, even most bikes work this way). I don't know of any other product that includes everything like this plus cabin lights. I'm rating this as "best yet" after dismissing many other options.
