Yes there's a switch easy to get too
No the batteries are not included.
I actually had my light fell off under my kitchen cabinets and it didn’t peel any paint. Probably since I didn’t really stick it properly the first time. If you have water base paint and it’s not really gloss, I think it should be easy to remove without any paint damage. Try using a spatula to remove
Other than making sure the batteries are good, put in position the right way, and the switch is on, I don't know what else to do.
I believe so, I don't know if they are water proof
Have it at the back door, so far so good and we have been having plenty of rain.
the nighlight is two piece simply slide the front off from the backing which attaches to your selected surface, turn it around and open the latch. intructions guide you on battery placement the rest of the way. replace when done.
Yes, but do not expect very much light
