My LED accent lights do that if I don't turn them off at their main switch.
My lights are hooked to the battery and have a push button on/off switch. I can turn this switch on and then use the remote to turn the lights off but if I do this they are still drawing power and drain my battery overnight.
If I leave them on with the remote but turn the main switch off I don't have any issues.
