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.
In some European countries there are regulations for bike lights, some even require cut-off beam like Germany. However in US the front light is dual purpose - it's illuminating the road at night and keeps salmoning bikers/runners/electric motors enthusiasts from running into you so a cut-off beam is counter productive for this purpose.
