Undocumented feature

Last week I noticed my storage room light would go into a loop. The light would turn on, stay on for a minute and turn off again, then turn itself back on. I thought this was caused by damage from the relays coil to the light whenever it was turned off. I had other things to do so I put the light sensor on my workbench to work on later. This morning I noticed my bedside light doing the exact same thing. It would turn on automatically and loop. This light has no relays in it so the first thing i thought of was to test the batteries in the other controller. Sure enough the batteries were low, all four read 1.1v on my multimeter. After replacing the batteries the light is now working fine. Just a heads up, the lights from harbor freight go into loops when the batteries are low enough. I don’t remember that in the manual.
