Yes. Businesses with show windows and lights must inform the office for business of the local council about it, also about any displays, lights, video screens etc. and must report the brightness. Brightness must not irritate traffic, traffic lights and such. The ad items have to be so dim that you can still see the breaking lights and direction indicators of other vehicles too. Otherwise some gross idiots would have flooded their area with light pollution scale brightness only to tell people they sell something.
