The Zefal light remote control button is a remote control for ZEFAL bike front lights that can be fitted to any part of the handlebars.
It makes controlling the lighting (switching on, off, changing modes) easier and safer, as you no longer have
to ride your bike one handed to switch the settings. Compact and lightweight, it plugs into the lighting's USB C port and attaches to the handlebars via a Velcro strap.
