SIR - According to Arqiva's spokesman, the six mast lights at Washford are the result of a review of "mast lighting policies" and "reflect current best practice" – in this case, the practice of going beyond what the law requires.

Presumably the three lights on each mast are intended to warn low-flying aircraft, very low-flying aircraft and tall pedestrians.

Following Arqiva's consultation with parish, district and county councils, not to mention affected residents (I'm afraid I missed the reports), is it proposed to add warning lights to other local high points such as the Brendon and Quantock Hills, and should local churches be encouraged to follow Arqiva's example?

Next time my grandchildren come to stay, I will explain to them that the energy used for the lights during the hours of darkness contributes relatively little to global warming, and that the pleasure of being able to see the night sky without the pollution of artificial lighting is as nothing compared to the pleasure of cursing individuals with nothing better to do than invent "current best practice".
