I got caught in a downpour yesterday evening, and had to turn my headlights on. After a while they started blinking off--turning off more accurately describes it. Anyway, they would go off (headlights, dashlights, taillights, everything) for about 15 - 20 seconds, then they would come back on for maybe 5 - 10 seconds. As I said it was raining hard, and I had the wipers on high (but they never cut out). This morning, I started the car and let it idle and turned the lights on, and they stayed on normally. It seems like maybe the rain was shorting it out, but I don't know how to fix it.
