PIR Security lights and battery chargers

My PIR security lights go on and off randomly all night long. I have found that if you charge up your battery drills and leave the charger on overnight ..this is what the cause is. As soon as you turn the battery charger off, the PIR lights work OK. Sat here in darkest Nottinghamshire, England, and wondering if I am alone with this problem.

Welcome to the forums from the UK.

Newer style battery chargers use switching power supplies and some can very dirty. I know with my tool battery chargers..... when they are running it wipes out the FM radio band.

You may be experiencing something similar although I have never heard of it bothering PIR type lights. Your lights may not be well shielded to reduce incoming AC line noise.
