WEST BIKING CW D399 Smart 2-in-1 Bicycle Rear Light with Wireless Remote Control: Wireless remote control
For the urban commuter or weekend trail rider, this West Biking tail light keeps you visible and in control. It's not just a safety accessory—it's your communication hub on two wheels, letting you signal turns and alert others without taking hands off the handlebars.
The wireless remote mounts easily to your grips, so a quick tap activates the turn signal lights before you merge into traffic. The high-decibel speaker cuts through city noise, and the USB fast charging means you're never caught with a dead battery mid-ride. With five light modes and life waterproofing, it adapts to any condition, from rainy evenings to sunny paths.
