Theres lots of great info on the issues and how to approach councils at the International Dark Sky Association web site.

The problem is that the majority of the lighting industry are geared to set businesses up with the biggest brightest lighting possible: its big $$$ for them. Only councils will be able to control the level of lighting and they don't pay the industrial power bills.
My light pollution problems come from an industrial estate across the valley. Once one new wharehouse came up with bigger brighter lighting , the whole street followed suit, and probably ego has something to do with it too
Perhaps we need a lighting campaign like the anti- speeding campaign. `Bright lighting?..no one thinks big of you '
