Lots of Astronomy, here. So, city discourages "light polution". Most neighborhoods have no "street lights". During a New Moon (or before moonrise/after moonset) most neighborhoods are *black*.
I don't know what cyclists are required to have by way of safety equipment, here. We have a large, internationally recognized bike race here each year so you frequently encounter large groups of cyclists "training" together (and is spandex a PREREQUISITE for riding a bicycle??).
Being "bike friendly", lots of cyclists on the roads -- along with lots of unusual bike configurations. The smart ones put a flag or some other attention getter on them so you can see them hiding behind an adjacent vehicle, etc.
