ancient lights

i must have walked past these ancient lights tens of hundreds of times, but today, for the first time, i noticed the sign which says “ancient lights”

they are on either side of the pub opposite my office called the Hope and there are two signs next to the two (ancient) lights.
it’s next to the Pollocks Toy Museum. next time you are in London, why not visit both attractions at the same time (and take me out for lunch as well)
