Sets out guidelines for control of the obtrusive effects of outdoor lighting and gives recommended limits for the relevant lighting parameters to contain these effects within tolerable levels. Refers to the potential effects of lighting systems on nearby residents, users of adjacent roads and transport signalling systems, and on astronomical observations. Does not apply to road lighting; internally illuminated advertising signs; brightly-lit surfaces (e.g. floodlit buildings and advertising signs); lighting systems installed for the purposes of television broadcasting; and lighting systems that are of a cyclic or flashing nature.
