Repair work

I quickly snapped this so apologies if it's not that good, as I was waiting to turn out and so had only one go at it. I just thought it was one of those moments you come across that are quite unique. The aerial is atop our local clinic, I guess it's for talking to ambulances or something. They might have been changing the lightbulb for the aircraft warning light as I noticed the red light later this evening and had never noticed it before. Of course I might be totally wrong but I just thought it would make an interesting blip for today.
