Welcome to the forum.

Cool commercial.

At the beginning of the video, how does the headlight know the rider is approaching for a ride, to turn on the headlight?

Is this smart like Kitt? Can William Daniels do the commercial voice over?

I change brightness for different conditions, which don't really match up with the video.

Low for dark bike paths -- I'm at a cruising speed, my eyes adapt to the darkness, I'm trying to be less annoying to other path users.
Low on climbs if I'm trying to extend battery life for the ride. I'm going slow and don't need more light.
Low on group rides, so I don't overpower the rider's light in front of me. I'm just lighting up the short distance to the next rider. Unless I'm on the front, then it's usually Bright.

Medium for level ground on dark country roads. Bright is too much for reflective signs! Again, my eyes are adapting to the darkness.
Medium is okay for quiet residential streets.

Bright for faster downhills -- I need to see much farther.
Bright for city riding -- I'm competing with car headlights and street lights. I want to stand out, and to not get my view of the road washed out by bright oncoming headlights.

I agree with rm-rf. In very dark conditions I need very little light once my eyes have fully adapted. OTOH, I want a much brighter light when surrounded by distracting lights and in order to stand out.

One of my few crashes occurred when a motorist didn't notice me while focusing on the headlights of cars behind me. As a result he pulled out into my path even though my headlight was shining in his direction. It's also why I want a flashing or pulsing light in urban conditions to stand out from other lights.

Very clever light.

When is this expected to be available to purchase? What is the expected MSRP?
