My '06 Subaru has the parking light 'option' too. Found out the hard way when they stayed on all the time and I couldn't get them to turn off without pulling the fuse. A quick call to Subaru led to the advice of 'look on top of the steering column for a switch'. Sure as heck, there was the switch that I must have inadvertently hit - I always thought it was the four way flasher but then a second look showed that was on the main console - and I've driven Subies for five years and never noticed this....?!
