This page helps you verify bulb sizes for the 2018 Toyota Sequoia by lighting position, so you can match the correct bulb to the correct lamp before you buy. The Sequoia uses a mix of LED and replaceable bulb types, and the exact fit can depend on trim, lighting package, market, and body style.
Use the bulb chart to check each exterior and interior location separately, including headlights, fog lights, turn signals, brake lights, reverse lights, license plate lights, dome lights, map lights, and stepwell lights. That makes it easier to confirm what your Sequoia needs without guessing from a generic parts listing.
Fitment can vary on the 2018 Toyota Sequoia, especially between trims and packages, so it is smart to compare your vehicle’s installed bulb before ordering. Some positions are LED assemblies, while others use replaceable bulbs such as 921, 168/917, 194/7441, 7440A, 7065, 2721, 7443R, or 74 depending on the location shown on this page. If you are converting from halogen to LED or replacing an aftermarket LED with another style, check polarity, connector shape, and available space behind the lens. For the most reliable result, inspect the old bulb or housing markings first and confirm the exact fit before purchase.
On this page, the headlight high beam and low beam are listed as LED. That means the bulb is part of an LED headlamp setup rather than a standard replaceable halogen bulb.
Yes. The front fog light bulb position is listed as LED for the 2018 Toyota Sequoia, so you should verify the lamp assembly rather than shopping for a standard fog bulb size.
The back up reverse light bulb is listed as 921. If one reverse light is out, confirm whether your vehicle uses a matching bulb on both sides before replacing it.
The license plate light bulb is listed as 168 or 917. Either designation may appear depending on the bulb brand or packaging, so match the installed bulb or socket listing before ordering.
The dome light bulb and map light bulb are both listed as 168 or 917. These interior positions commonly share the same bulb type on this model.
The rear turn signal light bulb is listed as 7440A. Make sure you are checking the rear signal position specifically, since front and rear signal bulbs are not always the same.
Both the brake light bulb and the tail light bulb outer are listed as 7443R. That makes it important to replace the correct rear lamp position, since the inner tail light uses a different bulb type.
The inner tail light bulb is listed as 194 or 7441. This is different from the outer tail/brake lamp on the 2018 Toyota Sequoia.
The vanity mirror light bulb is listed as 7065. If your vanity mirror light is dim or out, confirm the bulb shape and access method before replacing it.
Two stepwell light listings appear on this page: option 1 is 2721, and option 2 is 74. The correct one can depend on the original equipment installed on your Sequoia.
Yes. The parking light bulb, daytime running light bulb, and front side marker light bulb are all listed as LED on this page.
Because trim and lighting package differences can change the correct fitment. Checking the installed bulb helps you avoid ordering the wrong size, especially when the page shows multiple bulb options or LED assemblies.
