Common Toyota 4Runner Replacement Bulb Families
Across the model years covered in this guide, several bulb families appear repeatedly. Use these links only after confirming the bulb size for your specific model year and light position.
Toyota 4Runner Interior LED Light Kits
For drivers replacing several interior bulbs at once, a vehicle-specific kit can simplify bulb selection. The current SAWE 4Runner kits cover 2003–2023 and 1997–2002 applications. Always review the product compatibility information before ordering.
Toyota 4Runner Bulb Size FAQ
What bulb size does a Toyota 4Runner use?
There is no single bulb size for every Toyota 4Runner. The correct size depends on the model year and light position. Use the year-specific table above, then verify the factory bulb before ordering.
What size are Toyota 4Runner interior light bulbs?
Interior bulb sizes vary by year and location. The charts above show T10/194/168, DE3175 31mm, T5, and BA9S in different interior positions depending on the model year.
What reverse light bulb does a Toyota 4Runner use?
The reverse-light bulb varies by year. Many years in this guide list T15/912/921, while the 2000 model is listed with a 7443/7440-type application. Check the exact year row before purchasing.
What bulb size is the Toyota 4Runner license plate light?
Many of the model years covered in this guide list T10/194/168 for the license plate light. Because trim and factory configuration can vary, compare the original bulb before replacement.
Can I replace Toyota 4Runner interior bulbs with LED bulbs?
Many replaceable halogen interior bulbs can be replaced with compatible LED bulbs when the base, dimensions, voltage, and fitment match. Some factory LED assemblies are not serviced as a simple replaceable bulb.
Why does one 4Runner year sometimes show more than one bulb size?
A model year can have different lighting equipment by trim, package, or factory configuration. When more than one bulb is shown, verify the original bulb or vehicle documentation before ordering.
Related Bulb Size Resources
Important: Bulb-size information is provided as a fitment reference and may vary with 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.
