| Our verdict | This setup provides adequate multi-mode blinking patterns to satisfy basic legal riding requirements after dusk. Battery life on continuous high mode is limited by the compact casing. Check the integrity of the USB charging flap regularly to prevent moisture ingress. | The pairing of spotlight reach with floodlight peripheral coverage makes this a practical unit for dark commuter paths. Operating both emitters at maximum brightness will generate significant heat and deplete runtime rapidly. The mount requires firm tightening to prevent dipping over potholes. |
