Non-contact autopsy of dead sign light. (strobe warning)

While on my way home from work I spotted some street signage with pulsing LED lights. I took a closer look during the day and worked out why they were pulsing on and off.
It's one of those annoying things where you know what the problem is and how to fix it, but know that the fitting will just be swapped because it's cheaper to do that than repair them.
I'm travelling with work at the moment, so the audio and video will be very different from normal.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
