If you ride at night, you need lights to see and to be seen with. This particular light has become my favourite and fulfills both requirements. The Rockbros BC02-700C A54BK bicycle light looks like any regular flashlight and has a magnetic end that makes it easy to attach to any ferromagnetic surface. They’re reasonably priced at about SGD35 off Lazada.
The light is easy to install via a battery bracket with a threaded adjustable strap. I have mine mounted to my Insta360 camera mount using a rubber strap. This light has a 700-lumen bright and wide beam which provides excellent visibility while riding in low light conditions. It is rechargeable using a micro-USB cable and is IPX6 rated (resistant to rain and splashes). The battery lasts typically for about 10 hours of riding at medium intensity. The light offers 4 levels of intensity and 3 flashing modes to complement the 4 levels of steady-state lighting.
I’ve been so happy with this model that I have installed them on both of my bikes, and my wife’s bikes as well.
