Headlight bulb replacement restores nighttime visibility when original lamps dim or burn out. LED or halogen options fit most vehicle headlamp housings and signal assemblies.
- Base type and wattage must match the socket; mismatched bulbs can trigger dashboard warnings or melt housings.
- Color temperature affects beam appearance; 4300 K stays close to OEM halogen while 6000 K produces a cooler white light.
- Projector versus reflector housings change beam focus; check your model before choosing high-output LEDs.
Handle glass with clean gloves to avoid oils that shorten bulb life.
