2015 Toyota Vitz/Yaris exterior bulbs

Exterior bulbs are definitely fitted and relevant on the 2015 Toyota Vitz/Yaris. Technical references such as the Toyota Yaris/Vitz 2015 Owner’s Manual (XP130 series) and Toyota service/repair literature specify replaceable exterior lamps, noting that some trims use LED lamp modules that are replaced as an assembly. That means bulbs are a normal service item on this model.

The job of these bulbs is simple but critical: help the driver see and be seen. Headlights and parkers light the road and the car’s edges, indicators and brake lights signal intent, while reverse, fog and number plate lights keep things legal and safe. Depending on market and grade, headlamps are usually halogen (commonly H4 dual‑filament) with optional front fog lamps (often H11). Indicators are typically PY21W, park/position and number plate lamps are W5W, stop/tail are P21/5W or W21/5W, and reverse can be W16W/W21W. Always confirm the exact spec on the lamp cap label or in the owner’s manual, as trims and markets vary, and LED-equipped variants won’t take a conventional bulb.

As part of routine servicing, it’s smart to check all exterior lights every 10,000 km or six months. A quick walk‑around with the lights on, plus brake and indicator checks, will catch failures early. Replace bulbs in pairs on the same axle (both headlights, both tail/stop) to keep colour and brightness matched. If a bulb fails soon after fitting, check the relevant fuse and earth connections, and never touch a halogen bulb’s glass with bare fingers—use gloves or a clean tissue to avoid hot spots that shorten life.

• Watch for: slow or intermittent indicators, dim headlamps, blown fuses, moisture inside lenses, or bulb warning icons (where fitted).
• Replacement tips: confirm wattage and base type, ensure the bulb seats squarely, test all functions before refitting trims, have headlight aim checked after headlamp bulb changes.
• LED modules: where the Vitz/Yaris uses LED assemblies (e.g., certain DRLs or tail lamps), Toyota advises replacement of the complete unit—no globe swap—so factor in professional fitting.

Lastly, keep lenses clean and clear, and replace cracked or yellowed covers—good bulbs can’t shine through cloudy plastic. Dispose of failed bulbs responsibly at recycling points.

FAQs

What bulb sizes fit a 2015 Vitz/Yaris?
Bulb types vary by trim and market. Many halogen cars use H4 for headlamps, W5W for parkers/number plate, PY21W for indicators, P21/5W or W21/5W for stop/tail, and W16W/W21W for reverse, fogs are often H11. Always verify against the owner’s manual or the lamp’s cap label.

How often should exterior bulbs be checked or replaced?
Do a quick light check monthly and at every service. Replace on failure or when noticeably dim or discoloured. Swapping headlight or tail/stop bulbs in pairs keeps output even and avoids mixed colour temperatures.

Can they upgrade to LEDs legally in AU/NZ?
Only if the lamp housing and beam pattern remain compliant. Many retrofit LED “globes” aren’t approved for halogen housings. Use ADR/NZRTA‑compliant parts and get headlight aim checked, where the vehicle already has factory LEDs, replace the module with the correct OEM unit.
