    Hi, the head lamp and the intermittent wiper function are controlled by the LCM (Light Control Module), i don't know the cause for now but i recommand you to have a look in the battery box to check for loose connection because it's possible your LCM feel a voltage fluctuation and react like this. . . .

    I'm guessing you have a ground connection that's marginal. Did this happen after hitting some bumps on the road?
