Amazing the lengths people will go to in order to fix something that isn't broken. Change out all exterior bulbs with LEDs (plug & play). Done. A typical car battery will run them for days, if not weeks, and there is no vehicle made that requires the key to be on for the parking/clearance lights.
If you want to run the clearance lights WITHOUT the parking lights, then simply wire the clearance lights to a SPDT switch. The common in the switch goes to your clearance lights. One side goes directly to the house battery, the other side ties into the parking light circuit. With the switch in the first position, the clearance lights are powered directly from your house battery, in the other position they are powered when the parking/running lights are on.
That way, your can manually turn on just the clearance lights, but they will also come on automatically when you turn on your vehicle lights to drive at night.
