    On the subject of bike lights. Most of the current lights appear to use some LEDs which makes sense, of course. However the brightness of output light looks like completely unregulated.

    On so many occasions I would get blinded by overly bright lights of an incoming cyclist during late evening ride.

      That seems like an intentional design choice as truly unregulated LEDs without even ballast resistors will burn out.

      It's probably this way because companies design products to cater to their customers, who would likely prefer a Damn Bright Light to feel like they got their money's worth.

        They mean there's no policy regulating how bike lights can be designed, not that the LEDs themselves aren't electronically regulated.
