Anyone can tell me what this is ? Not sure if it exactly pertains here in the electronics forum but I think it does . What is this set up near my house and why is there a really bright red light on top of it https://imgur.com/a/9sYNkCd more pics https://imgur.com/a/VnSxd4t
Based on the concrete slabs with access doors and vent pipes around it, that's almost certainly a waste water lift station control and monitoring unit.
Lift stations are used when waste water drainage and/or local sewer lines collect at a point below the existing main sewers. They pump the water back up into the sewer system where it can be gravity fed to the water treatment facility. They are very common in fairly flat areas with a high water table (like South Florida, where the OP's pic was taken).
The red light on top can be used to indicate an active pump or alert to a failure. If the light is on for more than a few minutes, you should definitely call the numbers on the posted signs.

Adding to Phil C's answer.
The image below suggests that you want the waste water systems in your area to be operating "really well" at all times.
The location you identified is marked by the red symbol near the centre of the the images below.
The top image is from Garglabet maps, and the bottom version emphasises why you would want your waste water "lift" stations to be able to lift as required at all times.

While we are guessing, I throw out this one: Warning light for ICBM silo. If you see that thing turn on, run for cover.
It's probably a control box for a water pump, for a well, or maybe a sewage lift station. Who knows... and doesn't really matter.
I have one of these near me, mine is for a water pump.
