Parking lights won't turn off.

What is your question?

I stop the car,lock the doors - parking light is on !! Have to unplug cable to battery or else the battery will be dead by the end of work day.And I'm off work by midnight !!! Stress to plug it back on again in a dark parking lot ;) Any help with this problem would be highly appreciated - no money for high cost repair, shop :) Norski
