2016 Toyota Vitz / Yaris Exterior Bulbs

Exterior bulbs are definitely fitted to the 2016 Toyota Vitz/Yaris. This is supported by Toyota’s 2015–2017 Owner’s Manual and Repair Manual sections on “Lighting,” which list replaceable lamps and procedures, as well as Toyota’s Electronic Parts Catalogue that details part numbers for headlamps, indicators, tail/stop, reverse and number plate bulbs. Regulatory requirements under ECE/ADR lighting rules also make functional exterior lighting mandatory, so the part category is absolutely relevant to this model.

On this Vitz/Yaris generation, exterior bulbs handle critical jobs: seeing the road, being seen by others and signalling intent. That includes headlamps, front and rear indicators, parkers, stop/tail lamps, reverse lamps, front fogs (where fitted), number plate lights and side repeaters. Many trims use conventional halogen or incandescent bulbs, some variants may have LED modules for DRLs or parts of the tail lamp. Where LEDs are used as sealed modules, the lamp assembly is typically replaced as a unit rather than a simple bulb swap.

As part of routine servicing, a quick lighting check is a smart move. A walk‑around with the lights on, hazards flashing and the brake pedal pressed (with a helper) picks up most faults. Common signs a bulb is on the way out include dimming, a change in colour, or indicator hyper‑flash. Replace bulbs in pairs on the same axle for even brightness.

• Confirm the exact bulb type and wattage in the owner’s manual or by VIN in the parts catalogue, across trims it can vary (e.g., different headlamp or indicator bases).
• Switch lights off and let things cool. Under the bonnet or in the boot, remove the access cap, unplug the connector and release the spring/retainer. Avoid touching the glass, use gloves.
• Seat the new bulb fully, refit the dust cap and ensure gaskets are intact to keep moisture out. After any headlamp work, check aim to avoid dazzling oncoming traffic.
• If a lamp doesn’t work after replacement, check the relevant fuse and the earth connection. Persistent condensation usually points to a venting or seal issue.

For owners considering LED retrofits, only use ADR/NZTA‑compliant products and be aware that incorrect retrofits can cause warning behaviour (like hyper‑flash) or fail inspection. A simple schedule—inspect every 10,000 km or six months, and before a WOF/RWC—keeps the Vitz/Yaris visible and safe on Aussie and Kiwi roads.

Popular questions

What bulb types are used on the 2016 Vitz/Yaris?
Bulb types vary by trim and market. Most 2016 cars run halogen headlamps, with parkers, indicators, stop/tail, reverse and number plate bulbs as replaceable incandescents. Typical examples include H4 or H11/HB3 for headlamps and T10 (W5W) for parkers, with 7440/PY21W or P21W formats used for indicators/reverse on many trims. Always confirm by VIN or the glovebox manual before buying.

Are any exterior lights LED, and are they serviceable?
Some variants use LED modules for DRLs or parts of the tail lamps. Those LEDs are generally sealed and not serviceable as individual bulbs—if they fail, the lamp assembly is replaced. Where the Vitz/Yaris uses halogen/incandescent, the bulb itself is user‑replaceable.

Why is there condensation in a headlamp after a bulb change?
A brief mist after rain or washing can be normal, but persistent moisture usually means the dust cap isn’t seated, an O‑ring is nicked, or a vent is blocked. Reseating the cap and replacing tired seals typically fixes it, if water pooling is present, the housing may need repair or replacement.
