It looks like a UK bus. If you want to help make the bus company’s life miserable there is a useful trick. This is the sort of thing a lot of parish council members will get disproportionately angry about. They also tend to have far less to do than higher bits of government. They also know a lot more about the inner workings of local government, and who’s ear to burn about it. A politely written letter (or a few from several people) can get them up in arms about it.

Once you set that in motion, wait a week or 2, then also contact the local papers about it. I’ve seen them roll with far smaller stories than this.

Neither group has much/any hard power, but the soft power of the NIMBY croud can be extremely effective against public facing companies.

Edit to add.

It could be argued that that light is a statutory nuisance.
