London, like so many places, cannot makes up its mind when it comes to streetlighting. When I moved to London the downtown had these big, rectangular affairs with four illuminated globes at the top. Then the city decided to go with an antique looking light, one that encouraged thoughts of gas lamps in that other London in the 1880s.
Now, those lamps are being phased out and these modern looking globes installed. The main light illuminates the street and every so often there is an extra globe extended out and over the sidewalk. I like these latest streetlights. I hope they stay in favour for a while.
