They're changing, aren't they? Nobody over the age of 40 calls the flashing amber globes on those striped poles "Belisha beacons". Anyway, they're being replaced by glowing LED halos. Good idea. (And have you noticed the tiny stripes on the street lamps installed to give more visibility either side of zebras ? Perhaps not so useful).
My point is, this new luminaire technology is saving energy but does anyone else find them too bright? Same with daytime running lights (DRLs), required of manufacturers since early in 2010. The illuminated striped poles, and some LED lamp-heads themselves, actually dazzle at night ... and prevent me from seeing dark-clad pedestrians waiting underneath them !
