In my 2001 Outback, I have tail-clearance lights that are always on, i.e when car is off, and no key in ignition. The position of the headlamp switch does not affect the lights being on. I have to remove the 10A fuse to keep my battery from discharging.

 

I would appreciate any help on locating the electrical fault, i.e. a schematic, switch wand, relay, etc...

Look for a switch on the top of your steering column.

I don't suppose that the newer Outbacks have that little switch for the park lights on top of the steering column? And I don't suppose there's another person as dumb as me. I didn't know it existed and inadvertantly bumped it on and killed my battery 2 days in a row! ;^) Probably way too simple an answer!

Doh!, Its my wife's car so I almost never work on it and the switch was on. I never even knew it was there.
