Answer 1

Doesn't make any sense because the only control for the parking lights is the headlight switch on the dash.

I once did have my trailer plug get full of water and short across the constant supply to my lights and back-feed the parking light circuit, so my lights stayed on no matter what. Just an idea.

Next time it happens, pull the fuse and/or disconnect the headlight switch in the dash and see if that makes them shut off. It could help you narrow down the path of the problem for where the lights are actually getting power from. Can you tie this to anything else, like weather, or is it just as the battery runs down?
