Headlight Bulbs: what it does & when to replace it
Headlight bulbs light the road ahead; a burnt-out bulb is both a safety hazard and a common cause of a failed inspection. Bulb type varies (halogen, HID/xenon, or LED) and must match the housing — the fitment code (e.g. H11, 9005) is vehicle-specific. Signs include one side dimmer or out, or flickering. Many halogen bulbs swap from behind the headlight in minutes, though tight engine bays can make access awkward. Avoid touching the glass of halogen bulbs with bare fingers, as skin oil shortens their life.
DIY difficulty: Easy DIY (match the bulb fitment code). Always confirm the correct part for your exact build by VIN before buying.
