Use this Toyota Yaris bulb size guide to find replacement bulb sizes for 2005–2019 Toyota Yaris exterior lighting, plus interior bulb fitment for the 2007–2011 and 2012–2019 year groups. The supplied data covers headlights, fog lights, reverse lights, brake lights, parking lights, side markers, rear turn signals, tail lights, map lights, dome lights, trunk lights, and license plate lights.
The exterior chart covers a broad 2005–2019 range, while the interior-light data is split into two year groups because dome-light fitment changes. Use the exact section below before ordering.
Choose the complete interior LED kit that matches the Yaris model-year range.
These bulb families appear in the supplied Yaris charts. Use the fitment table first, then choose the matching bulb family.

There is no single bulb size for every Yaris light position. The correct bulb depends on whether you are replacing an exterior or interior light and, for interior bulbs, the model-year range.
The supplied 2005–2019 exterior chart lists H4 for the combined high-beam and low-beam headlight position.
T15/912/921 is listed for the back-up-light position in the supplied 2005–2019 exterior chart.
7443/7440 is listed for the brake-light position in the supplied exterior chart.
T10/194/168 is listed for the license-plate-light position in both supplied interior year-group charts.
For 2007–2011, the supplied chart lists T10/194/168 for the map light and DE3175/31mm for the dome light. For 2012–2019, T10/194/168 is listed for both map and dome lights.
Important: Bulb-size information is provided as a fitment reference and may vary by exact model year, trim, body style, factory lighting equipment, or regional specification. Confirm the original bulb before purchase.
