the Cygolite Hotshot is effective. Some improvements I'd prefer to see with it are more durable & assorted mounting options, 4x battery life, type C charge port, wireless remote switch or BT syncing for on/off, & the ability to preset the setting for turn on illumination. If that means a bigger device, so be it. I'm not going to fret the weight if I am using a light during a ride. If I don't want the weight, I'd remove the accessories.
