The 2020 Toyota Sequoia uses a mix of LED and replaceable bulb types, and this page is designed to help you verify bulb sizes by lighting position. Whether you are replacing a burned-out lamp or planning a full refresh, checking the correct bulb for each location can save time and prevent fitment mistakes.
For the 2020 Sequoia, several exterior lighting functions are LED, including the headlight high and low beam, fog light, daytime running light, parking light, front turn signal, side marker, center high mount stop light, and door mirror illumination light. Other positions still use serviceable bulbs such as 921, 168, 194, 7440A, 7443, and related sizes, so it is important to match the bulb to the exact lamp location.
Fitment can vary by trim, lighting package, market, and body style, so always confirm the bulb type for your specific vehicle before ordering. Some Sequoia models may have factory LED assemblies that are not serviced with a simple bulb swap, while others use standard replaceable bulbs in interior, rear, and utility lighting positions. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, and beam pattern are compatible with the housing. The safest approach is to compare this page with the bulb already installed in your vehicle before purchase, especially for exterior lamps where a halogen-to-LED change can affect brightness, warning messages, or light output pattern.
The headlight high beam and low beam positions are listed as LED on the 2020 Toyota Sequoia. That usually means the light source is built into the assembly rather than replaced with a standard bulb.
The front fog light bulb is listed as LED. In many cases, that means the fog light is part of an LED unit rather than a conventional replaceable bulb.
The backup reverse light bulb is listed as 921, and the backup light bulb is also listed as 921. Check the exact lamp location on your vehicle to make sure you are replacing the correct socket.
The license plate light bulb sizes listed for the 2020 Sequoia are 168 and 917. Either size may appear depending on the specific lamp position and configuration.
The dome light bulb is listed as 168. This same size is also used in several other interior and cargo-area positions on this vehicle.
The map light bulb is listed as 168. If your overhead console has more than one lamp, verify each socket before ordering replacements.
The rear turn signal light bulb is listed as 7440A. This is different from the front turn signal setup, which is listed as LED.
The brake light bulb is listed as 7443R, and the outer tail light bulb is also listed as 7443R. These are separate from the inner tail light bulb listing.
The inner tail light bulb is listed as 194 or 194R. The correct choice depends on the exact lamp position and housing setup.
No. The front side marker light bulb is listed as LED, while the rear side marker light bulb is listed as 7443. Always check front and rear positions separately.
The glove box light bulb is listed as 74. This is a small interior bulb and should be matched carefully to the socket size.
Because trim and lighting package differences can change the bulb type, and some positions may have been updated with aftermarket parts. Checking the installed bulb helps confirm the correct base, size, and style before you order.
