2018 Toyota Vitz/Yaris Headlights

Headlights are absolutely fitted to the 2018 Toyota Vitz/Yaris. This is confirmed by Toyota’s 2018 Vitz/Yaris owner’s manual and Toyota Electronic Parts Catalogue (XP130/XP150 series), which list headlamp assemblies, bulbs, and fuses as service items. Regulatory frameworks like Australian Design Rule 13/00 and New Zealand’s Land Transport Rule: Vehicle Lighting also require compliant headlamps on passenger vehicles. So yes—headlights are relevant and used on this model.

On the 2018 Vitz/Yaris, the headlights do the heavy lifting for safe night and low‑visibility driving—providing low beam for everyday use and high beam for open roads. Depending on trim and market, the vehicle may have halogen reflector/projector lamps (commonly H4 or 9012/HIR2) and, on some grades, factory LED units with automatic light control and manual levelling. Beyond lighting the way, they make the car visible to others and keep it compliant with ADR/NZ road rules.

As part of routine servicing, the headlights deserve a quick check. Halogen bulbs gradually dim with age, so replacing in pairs helps keep beam colour and brightness consistent. Many workshops suggest proactive replacement every few years or when output noticeably drops. For halogen units, bulb access is through the rear of the headlamp: disconnect the connector, release the clip, swap the bulb, and refit the dust cover—avoiding any contact with the glass. If a grade has sealed LED modules, the service path is typically replacing the lamp assembly rather than a globe change, which a qualified technician should handle.

• Inspect lens clarity, UV‑exposed polycarbonate can haze. Use headlight‑safe cleaners or a restoration kit—no harsh solvents.
• Check aim after pothole hits, minor prangs, or suspension work. Correct alignment stops glare and maximises road coverage.
• Look for moisture inside the housing, persistent fogging means checking caps, seals, and vents.
• Verify fuses and headlight relays if both sides drop out, consult the fuse map in the owner’s manual.

Owners who want brighter light should stick with ADR/NZ‑compliant parts. LED “retrofit” globes in halogen housings may not be legal or safe without proper certification and optics. Keeping everything genuine‑spec—or quality aftermarket that’s compliant—keeps the Vitz/Yaris safe, road‑legal, and easy to live with.

Popular Questions

What bulb type does the 2018 Vitz/Yaris use?
Most variants use halogen H4 or 9012 (HIR2) depending on the exact trim and market, while some higher grades feature factory LED headlamps. The owner’s manual and parts catalogue for the specific VIN will confirm the correct type.

Can LED bulbs be fitted to a halogen headlight?
Retrofit LED globes in halogen housings may not meet ADR/NZ lighting rules unless the complete headlamp is approved for LED. Beyond legality, beam pattern and glare can be compromised. The safe path is OEM LED assemblies or ADR/NZ‑compliant conversions tested for that housing.

How often should headlight bulbs be replaced?
Halogen bulbs dim over time, many technicians recommend replacing in pairs every few years or at the first signs of reduced output or colour shift. LED assemblies generally last much longer but should be inspected for faults or moisture during regular servicing.
