A light is required at night here in San Diego a rear light is not required but few commuters ride at night without one. I have rear blinky for decades and I rarely ride at night and do not commute.
Riding on the side walk is generally unsafe and sometimes illegal. While this rule applies to children I would be suprised if ever enforced. If you ride at a normal adult speed you do not belong on the sidewalk.
