Both headlights in your 2003 Hyundai Sonata stopped working same time what happened?

If both headlights in your 2003 Hyundai Sonata stopped working simultaneously, it could be due to a blown fuse, a faulty headlight relay, or a wiring issue. Check the fuse box for a blown headlight fuse, as this is a common cause. If the fuse is intact, inspect the headlight bulbs and wiring for any damage or corrosion. If the problem persists, it may require a closer inspection by a professional.
