I seem to end up asking about this every couple of years - best
bike lights for urban use? Some level of illumination of the
potholes ahead, lightweight and easy on batteries, easy to
attach/remove, up to say £50?

Lidl/Aldi lights are adequate to good. Who needs "best"?

Someone who prefers not to be cut up by other road users who don't
notice their twinkle against a background of bright car lights?
