Thin blue line

A dreadful day weather wise today, grey and wet all day. Only left the house to deliver some forgotten shopping to my aunts in the next village.
I have had this shot in mind for a while. One of the neighbours over the back has some blue fairy lights which are up and on ALL YEAR round. Thankfully not as annoying as the flashing Christmas lights at the front but I always see them as I head into the bathroom.
With recent ambulance strikes they make me think of a siren light from the emergency services. Tonight with little or no inspiration I have zoomed in to as not to shot the window fastener and of course bathroom glass is obscured
