> I expect to be able to walk on sidewalks without a flashlight. There are any number of ways to provide illumination that also mitigates light pollution. This generally means placing metal hats on any external light sources (vertical or horizontal) that effectively pushes the light down and minimizes leakage. The worst offenders in my area are the globular light sources that emit light in all directions.
