I bought my SEL as a used car last week and saw this forum. We were having a very heavy rain today. BTW, I'm in Ohio part time and Florida as a snowbird. This was in Ohio, so not in Andrea's wake. I set the wipers on constant low, the headlights on auto and after a minute or less, the headlights came on. We continued our trip and later, before arriving at our destinatation, the rain had stopped. I shut off the wipers and a minute or less later the headlights shut off. I have to believe the "setting" worked proper. Thanks so much for this forum, it's helping me learn what the manual doesn't do...understand function. Fred
