Do I need the app to use these lights?

No. Both lights work with their built-in modes from the buttons. The app adds mode tuning and battery readouts.

How long does the headlight run at full power?

Full 1000-lumen output is short-lived, roughly an hour or so. Lower modes stretch runtime toward the long end of the range.

Yes. The set includes the 1000XL headlight and the KTV Pro Smart taillight, and both charge over USB.

The headlight mounts to the handlebar and the taillight to the seatpost. Both mounts are included and fit standard round bars and posts.

Yes. Both lights are rated waterproof and owners report them holding up in rain and road spray.

You get a matched taillight and app control in one set. A standalone headlight may be simpler, but you would buy a rear light separately.
