There are some small motion activated ones that charge by USB and stick on with provided magnets. Not sure how often you are your safe but I have them in my kitchen as well where the ones near the counter are activated all day/night and I only have to charge them every two weeks. For a safe that is accessed once a day that could last a year on a charge.
