Here’s the punchline: the lights are always being tested. All year round. You might see a flash of red and green in July. It’s not a ghost. It’s a technician checking a plug.
So really, the lights never fully go off. They just go into hiding. They’re waiting for you to walk by in August and say, “Wait, was that a snowflake?”
Go see them before January 6th. Or enjoy the weird, lonely glow of a late January bulb. Either way, London’s lights are just playing hide-and-seek with your emotions. And they always win.
