Generally one of two things. Most likely the battery needs to be renewed as it is not charging/holding charge. Second your alternator is working inefficiently. You can check the alternator first by getting a multimeter across the battery terminals when the car is running.

If both of these check out fine try disconnecting the boot light,it may just be staying on and is very difficult to check that it is going off when the lid is closed.

Or the glove box light.

The boot light isnt difficult to check - chuck someone in the boot and shut them in, if they start screaming to be let out cause its dark in there, its a fair bet the switch is working - (its best if its someone you know, not a random pedestrian, I used my brother)
Someone on here did suggest using the video facility on their phone to see if the light was going out.
