They only light up when it is dark and motion is detected

One of mine didnt work properly and the seller immediately responded and sent me a replacement at no additional charge without requiring that i return the defective one

Only 2 out of the 3 in the box worked not worth my time to send back because of one defected unit

Youd think the factory would do a quick test on each unit before packaging but i guess not

My initial concern with this light is that although the motion sensor works perfectly and instantly the light stays on for only 10 seconds unless further movement is detected not long enough for a middle of the night trip down the hall

For me but perhaps not for you the negatives are that its brighter than id choose that i do need to move the switch between auto and on if i want more than 10 seconds of light and not usb charging

Quite bright motion sensor lights that are easy to install

I have not had any product with selfadhesive strips that has decent longevity so this is not specific to this product
