The 2021 Toyota Land Cruiser uses LED low-beam and high-beam headlights. The supplied fitment data does not list a replaceable halogen bulb number for either headlight, so confirm the factory lighting assembly before ordering a replacement. The fog lights, daytime running lights, brake lights, center stop light, tail lights, rear side markers, license plate lights, and interior dome, map, and trunk lights are also LED.
For exterior bulb replacements, the front turn signals use 7444NA bulbs, while the rear turn signals use 7440. The front side markers use 168 bulbs. No reverse-light fitment is listed in the supplied data, so a bulb size should not be assumed for that location.
Because the main exterior lighting is LED, replacement needs may involve the complete lamp assembly or a vehicle-specific LED component rather than a conventional plug-in bulb. Verify the existing part and socket before purchasing.
