This page covers the 2021 Toyota Land Cruiser and helps you verify bulb sizes by lighting position. Whether you are replacing an exterior signal lamp or an interior cargo light, matching the bulb to the correct location is the easiest way to avoid ordering the wrong part.
The 2021 Land Cruiser uses LED lighting for many positions, but a few spots still use replaceable bulbs. Because trim and lighting package details can vary by market and body style, it is important to check each lamp location carefully before buying replacements.
For the best fitment results, compare the bulb chart on this page with the bulb already installed in your vehicle, especially if your Land Cruiser has a different trim, regional specification, or factory lighting package. Some positions are LED modules rather than serviceable bulbs, while others may use a standard halogen-style bulb or a specific socket type. If your truck has been modified with aftermarket LED conversions, the original bulb size may still be listed here, but the actual setup can differ. Always confirm the installed bulb, connector, and housing style before purchase so you do not end up with a part that fits the socket but does not work correctly in the vehicle.
This page lists the bulb sizes by lighting position for the 2021 Toyota Land Cruiser, including LED-based lamps and the few replaceable bulb types such as 921, 168, 7444NA, and 7440 where applicable.
Yes. The headlight high beam and low beam are listed as LED on this page, so the headlamp assembly is not a simple bulb-only replacement in the way older halogen systems are.
The front fog light bulb is listed as LED. That usually means the light source is integrated into the lamp assembly rather than being a standard removable bulb.
The back up light bulb is listed as 921 for the 2021 Land Cruiser.
The front side marker light bulb is listed as 168.
The front turn signal light bulb is listed as 7444NA.
The rear turn signal light bulb is listed as 7440, and it is marked as optional on the raw list provided for this page.
On this page, the brake light bulb, tail light bulb, center high mount stop light bulb, license plate light bulb, daytime running light bulb, dome light bulb, map light bulb, trunk or cargo area light, and rear side marker light are all listed as LED.
Yes. Trim, body style, and market can change the lighting package, so the bulb chart should be used as a guide and verified against the actual vehicle.
Bulb fitment depends on where the lamp is located. A Land Cruiser may use different bulb types for the front turn signal, rear turn signal, backup light, and side markers, so separating them by position helps prevent mistakes.
Not unless the housing is designed for it. Many of the 2021 Land Cruiser lighting positions listed here are LED assemblies, so swapping to a standard bulb is usually not a direct replacement.
Check the installed bulb, the socket style, and the lamp location. If your Land Cruiser has aftermarket lighting or a different regional package, the bulb listed here may not match every vehicle exactly.
