Should I replace both headlights if one goes out?
If one of your vehicle's headlights goes out, you may be wondering if you need to replace both headlights or just the one that's not working. The short answer is that it's generally recommended to replace both headlights at the same time, even if only one has burned out.
Why Replace Both Headlights?
There are a few key reasons why it's best to replace both headlights when one goes out:
- Matching light output: Headlights are designed to work in pairs, providing balanced illumination. If you only replace one, the new bulb will be brighter than the older one, creating an uneven light pattern that can be distracting and unsafe for other drivers.
- Consistent appearance: Replacing just one headlight can make your vehicle look uneven or mismatched. Replacing both headlights ensures a uniform, clean appearance.
- Longevity: Headlight bulbs tend to wear out at similar rates. Replacing both extends the life of your headlight system and ensures you don't have to replace the other bulb soon after.
Additionally, many vehicle manufacturers recommend replacing headlights in pairs to maintain proper lighting performance and safety.
When Can You Replace Just One Headlight?
There are a few rare instances where you may be able to replace just the one burned-out headlight:
- Newer vehicles: Some modern cars have headlight assemblies that are designed to be easily replaceable as individual units. In these cases, you may be able to just swap out the single faulty headlight.
- Identical replacement: If you can find an exact replacement bulb that perfectly matches the age and condition of the working headlight, you may be able to just replace the one that's out.
- Temporary fix: As a temporary measure, you can replace just the burned-out headlight to ensure your vehicle is street legal. However, you should still plan to replace both headlights as soon as possible.
In general, though, it's best to play it safe and replace both headlights at the same time for optimal performance and appearance.

Why are both my headlights burning out at the same time?
Vibrations from a rocky road or worn-out tires can cause the headlight's filament to break. They also happen when the bulb isn't mounted securely.. Touching the headlights repeatedly causes hot spots to form on the bulb. The physical contact causes uneven heating, so use gloves when handling the bulbs.
