I was stuck in traffic and was bored . I some how came to the realization that if the winshield wipers are on the head lights will turn on. I then turned off the wipers and the lights shut off after about a minute. It seemed to me that the light outside was bright enough so that the lights should not have turned on (it was raining slightly).

Anyhow, through bordom :p I happened to stumble on this and wanted to know if someone else could confirm this. They do not seem to turn on and shut off right away, I would say within a minute or so.
