Headlights can fail or go dim for a wide variety of reasons. The most common reason is also the most simple: The bulb or bulbs in your headlights have reached the natural end of their lifespan. Just like normal bulbs used in your home, headlight bulbs will degrade over time, and will eventually stop working altogether. This can be alleviated by stopping in for a headlight replacement appointment.

However, failing headlights may also point to a greater problem with the vehicle’s electrical power system, such as an issue with a sparkplug or a problem with the vehicle’s battery. These sorts of issues usually result in lighting problems throughout the vehicle, which may manifest as interior lights fading.

How Long Do Headlights Typically Last?

There are many factors to be considered when estimating a headlight bulb’s lifespan. However, most traditional headlights should last anywhere from 500 hours to 1,000 hours.
