Given the limited information, the short answer is YES. A fusible link or the car's version of a circuit breaker is responsible for the headlights and other accessories. There may be other things not working that you haven't identified yet. Since it's extremely rare for both headlights to cease working at the same time, either 1 stopped a little earlier and it went unnoticed, or there's an electrical problem (likely a fusible link) that is the cause. It's been my experience that automobile electrical specialists are much better than dealerships or regular service stations at diagnosing these problems. They don't come cheap but it's usually $$$ well spent. Best of luck with your headlight problem. Greg
