Interesting. A couple of weeks ago, I came home in a heavy rain with the Euro switch in ON and fogs ON. Parked and shut the garage door, thinking that the coming home feature would shut off the lights in 30 seconds. An hour later, I remembered that I had left the fogs on, and went back out to the garage, expecting to see the lights still on. I was pleasantly surprised to see that all the lights were off with the light switch still in the fog position.
