Use this Toyota Tacoma bulb size guide to find replacement bulb sizes by model year and light position. The charts below cover common exterior and interior lighting positions, including high- and low-beam headlights, fog lights, reverse lights, brake lights, turn signals, daytime running lights, parking lights, map lights, dome lights, license plate lights, trunk or cargo lights, and other replaceable bulbs.
Tacoma bulb fitment can change between model years, trim levels, factory lighting packages, and regional specifications. Start with your exact model year or year range, then locate the light position you want to replace. When more than one bulb size is listed, compare the original bulb or check the vehicle manual before ordering.
Prefer a complete interior upgrade instead of selecting individual bulbs? SAWE offers Tacoma interior LED kits for several model-year ranges.

Several bulb families appear repeatedly across the Tacoma model years covered in this guide. Use these links after confirming the correct bulb size for your exact year and light position.
For owners replacing multiple interior bulbs at once, a model-year-specific kit can simplify bulb selection. Review the product compatibility details before ordering.
There is no single bulb size for every Tacoma. The correct bulb depends on the model year and light position. Use the year-specific chart above, then verify the original bulb before ordering.
The headlight bulb varies by generation. The 2005–2015 chart lists H4/9003/HB2 for combined high and low beams, while later Tacoma years in this guide list H11 for several headlight positions. Check the exact year range before purchasing.
Many Tacoma years in this guide use T15/912/921 for the reverse light. The 2000 chart lists 1156/BA15S for the reverse-light position, so model year matters.
Many of the Tacoma years covered here list T10/194/168 for the license plate light. Verify the original bulb because equipment can vary.
Interior bulb sizes vary by year. T10/194/168, DE3175 31mm, 211-2/578 41mm, and T5 appear in different interior positions across the model years in this guide.
Many replaceable halogen interior bulbs can be upgraded to compatible LED bulbs when the base, dimensions, voltage, and fitment match. Factory LED assemblies may not use a separately replaceable bulb.
A model year can have different lighting equipment by trim or factory package. When more than one bulb is shown, verify the original bulb or vehicle documentation before ordering.
Important: Bulb-size information is provided as a fitment reference and may vary by trim level, factory lighting package, or regional specification. Confirm the original bulb before purchase. If you find a discrepancy, contact SAWE Lighting support so the guide can be reviewed.
