Replacing a blown headlight or tail light globe is one of the quickest and cheapest DIY car repairs. Most globes cost between $5 and $30, and the job takes 5 to 15 minutes on most vehicles. However, the access method varies significantly between vehicle models, which is why having the correct procedure matters.
Identifying the Correct Globe
Automotive globes come in many different fitting types (H1, H4, H7, H11, 9005, 9006, and many more). Using the wrong type will not fit in the socket. Your workshop manual or the existing globe itself will identify the correct type. Some vehicles use different globe types for low beam, high beam, and parking lights within the same headlight assembly. For tail lights, the brake light, indicator, and reverse light globes are often different types.
Headlight Globe Replacement
Most headlight globes are accessed from behind the headlight assembly through the engine bay. Open the bonnet and locate the back of the headlight unit. There is typically a dust cover (rubber boot or plastic cap) that twists or pulls off to expose the globe holder. Disconnect the electrical connector, release the retaining clip or twist the globe holder anticlockwise, and remove the old globe. When handling the new globe, do not touch the glass with bare fingers, as the oils from your skin create hot spots that can cause premature failure. Use a clean cloth or gloves. Insert the new globe, secure the retainer, reconnect the plug, and refit the dust cover.
Some vehicles (particularly those with tight engine bays) require removing the headlight assembly entirely, removing the air filter box or battery, or accessing the globe through the wheel arch liner. Your workshop manual shows the specific access method for your vehicle.
Tail Light Globe Replacement
Tail light globes are usually accessed from inside the boot or cargo area. Open the boot and look for a trim panel or access cover behind the tail light. Remove it (clips, screws, or thumbscrews) to expose the back of the tail light assembly. The globe holders typically twist out anticlockwise. Pull the old globe straight out of the holder and push the new one in. Some modern vehicles use LED tail lights that are integrated into the entire assembly and cannot have individual globes replaced.
Halogen vs LED vs HID
Standard halogen globes are straightforward replacements. If your vehicle came with HID (xenon) headlights, the ballast and igniter are part of the system and HID globes require careful handling (they contain gas under pressure). LED headlights in factory-fitted units are typically integrated into the assembly and are not user-replaceable. Retrofitting LED globes into halogen headlight housings is not ADR-compliant in Australia for road use and can create dangerous glare for other drivers.
