On both our Crossfire and E350 there are the two positions to the left of off that operate the offside parking lights. Try as I may, when the boss parks the car about 50% of the time one side ends up turned on and since I don't drive every car we have often we end up with dead batteries. Neither car will likely ever be parked curbside in the city, we live in the sticks and might see big city/curb parking once or twice a year and typically use one of our more "beaters" for that duty. Has anyone disabled those switch positions? Thanks!
