In my case the headlight was out until I opened the hood and then closed it. The shock of dropping the hood 12 inches made the headlight start working again. This "trick" worked twice in the following 3 days or so and then the light was out for good. I thought I had a wiring or socket problem but it was the bulb. The parts guy at the Hyundai dealership where I got the new light bulb from said this is pretty common. |
