Likely one bad capacitor on the board that loses its ability to store
charge in low temps. Given the 'blinking' it is most likely the
bootstrap cap. which allows the main supply regulator chip to start up
to power the "motion sensing" parts.

The choice of the add-on motion sensor especially. Need nearly a
180-degree sensitivity and a great service-life profile.

I've been using these:
amazon.com/gp/product/B0CCF3HYT9
The sensing angle is about 100 degrees but you do get six of them along
with mounting brackets. Also the output is digital not analog. There are a number of other options but I think the all use the same sensor. It's adjustable for range and sensitivity.
https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor/ overview
has information on how they work and some of the adjustments. The ones I
have are very close to Adafruit's new design. Follow the pages and there
is a simple diagram with batteries, the module, and a LED, no Arduino. You could do something like that but drive a FET to control the main LED.
Alas all the little ones are rated for 40w max, which is fine if you
stick to LED bulbs, but SOMEBODY might stick a filament bulb in there
someday.

That one claims 50W. If you're really paranoid you it to drive

There's tons of stuff for the electronics hobby market,
but for real-world line-connected there's not as much.

It takes 3 D cells and they last a long time it the raccoons don't hold a square dance on the deck. I first bought one to try to dissuade the coons
but they like to see what they're eating and thanked me for the improved ambiance. Then as the days got shorter I realize it was a lot handier than fumbling with the lock like I'd been doing for 30 years. The cat has
worked out the coverage and seldom triggers it.
When the batteries are getting weak it triggers repeatedly which is as
good as an additional low battery indicator. I had one of those on a LED flashlight and it earned its keep by draining the battery so it could show how well it was doing its job. later iterations of the flashlight skipped that 'feature'.

That product number brings up a LED flashlight
in the USA :-)
Yea, I could BUILD something out of parts, but not sure my
insurance company would be very understanding. They expect
certified components dedicated to the exact task at hand.
