IMALENT BG10, “Firefly” is a magnetic rechargeable bicycle light that can solve almost any problem with today’s riders. Its OLED display clearly shows the current output levels such as brightness, capacity and run time. Thanks to Imalent’s premium reflector design, we have already done this, so the BG10’s beam is wider than the other models in this category. 

The BG10 solves three key issues facing modern riders: 

– The light will adjust the brightness to ensure it doesn’t make anyone blind on the road (powerful features bring great responsibility!) 

– Cut-off line ensures you and others stay safe . 

– Charging on the go, a simple mobile power supply will ensure you never run out of juice!
