Changing the bulbs

I've come across these workers changing the bulbs of the street lights - apparently they are substituting regular ones by leds.

Lovely capture, that must be a big job to change them all

Interesting shot that tells a story.

@bkbinthecity @mittens Thanks a lot! @bigmxx Thanks! In fact, they started years ago - there are different lamplights models, so I guess some are easier to provide with leds.
