Pir entrance light flashing

[Maggotstein]

Hi. My PIR entrance light flashes on and off about 4 times before turning off at the end of its time cycle.
Any ideas what might be the cause/ remedy for this? It’s been installed for a couple of years and has only started doing this a few months ago. It’s bloody annoying now.

Haven’t had it off to check inside but it’s doubtful as it’s sheltered by a porch and canopy

Likely the light is faulty- the PIR sensor / daylight sensor.

Assuming you've tried checking any adjustments, which make no difference.

In which case just replace it, normally not worth trying to repair these.

Ok thanks for the advice
