It could be a dome light. To find out what is draining the battery overnight you need to take off the negative battery terminal and put a test light or Voltage tester between the 2 terminals. With everything off and all the doors shut or open if you have the dome light turned off, the test light or voltage tester will light up or show voltage. Go to the fuse block and take a fuse out one by one. If the light goes out when you pull a particular fuse, then that is the circuit that is draining the battery and you can take a closer look at it.
