Few hours later, the light flickered on and off repeatedly for ~15 seconds and then went away. The next day, driving at night on the freeway, the light came back on and both headlights turned off. I cautiously pulled over, and set my emergency lights on. I flicked the headlight switch on and off repeatedly and they came back on. Drove for another 10 mins and the driver side headlight turned off, and the passenger headlight stayed on. …”
