Use this Toyota Tundra bulb size guide to find replacement bulb sizes by generation and light position. The supplied charts cover 2000–2021 Toyota Tundra applications for headlights, fog lights, reverse lights, brake lights, turn signals, parking lights, side markers, license plate lights, map lights, dome lights, courtesy lights, tail lights, and other replaceable bulbs.
Tundra bulb fitment changes across model-year groups. Early trucks use an H4 combined high/low headlight, while the 2007–2013 chart also includes separate 9005 high-beam and H11 low-beam applications. Reverse, fog, rear exterior, and interior bulb families also vary, so choose the exact year range below before ordering.
For a complete interior-light upgrade, choose the kit that matches the Tundra model-year range. These product links are preserved from the supplied page.
These bulb families appear repeatedly in the Tundra charts. Use the year-specific table first, then choose the matching replacement category.
2000–2004: the supplied chart lists H4/9003/HB2 for the combined high/low headlight, 9006/HB4 for fog lights, T15/912/921 for reverse lights, and DE3175/31mm for dome, map, and selected trunk-light positions. Rear exterior positions can use 7443/7440 or 3157/3156 depending on the light.
2005–2006: H4 remains the combined headlight and 9006 remains the listed fog-light bulb. Reverse remains T15, while the dome-light listing changes to 6418/6411 36mm and the map light is listed as T10/194/168.
2007–2013: the chart includes H4 for the 2013 combined headlight entry, plus 9005/HB3 high beam and H11/H8/H9 low beam entries. Fog changes to 9145/H10/9140, reverse is primarily T15, and T10/194/168 appears in several interior and marker positions.
2014–2020: the supplied chart lists H4 combined high/low headlights, H11 fog lights, 7443/7440 reverse lights, 3157/3156 for many brake, parking, tail, and DRL positions, and T10/194/168 for map, dome, license plate, and selected interior lights.
2021: the chart continues with H4 combined headlights and H11 fog lights. It lists 7443/7440 for the front turn signal and reverse positions, 3157/3156 for several brake, parking, tail, and rear-marker positions, and T10/194/168 for map, dome, license plate, and marker positions.

There is no single bulb size for every Tundra. The correct bulb depends on model year and light position. Use the year-specific chart above and verify the original bulb before ordering.
The supplied charts list H4/9003/HB2 for 2000–2006, 2014–2021, and the 2013 combined-headlight entry. The 2007–2013 section also lists 9005/HB3 high beam and H11/H8/H9 low beam applications.
The supplied 2000–2013 charts primarily list T15/912/921 for reverse or back-up positions, with a 2013 alternative also shown. The 2014–2021 charts list 7443/7440 for reverse or back-up light positions.
T10/194/168 is listed for the license-plate-light position across the supplied Tundra year groups shown on this page.
T10/194/168, DE3175/31mm, and 6418/6411 36mm appear in the supplied interior-light charts depending on year range and position. Use the exact year-specific table above.
No. The complete bulb-size charts on this page run through 2021. One interior LED kit link covers later model years, but that product coverage is not a complete 2022 exterior bulb-size chart.
Some positions can vary by trim, factory lighting equipment, lamp assembly, or production date. When a row shows “OR,” compare the bulb already installed in the truck before ordering.
Important: Bulb-size information is provided as a fitment reference and may vary by trim, factory lighting equipment, production date, or regional specification. Confirm the original bulb before purchase.
