Land Rover Discovery 2021 Bulb Size
Bulb size chart
This page helps you verify the bulb sizes and lighting types for the 2021 Land Rover Discovery by lighting position. Whether you are replacing a headlight, turn signal, license plate light, or interior lamp, checking the correct location first makes it easier to find the right fit for your vehicle.
The 2021 Land Rover Discovery uses LED lighting for many exterior and interior positions, but the exact setup can still vary by trim, body style, and market. Use this page as a practical reference when matching the bulb type to the specific lamp location on your Discovery.
Before buying replacements, confirm the lighting package on your Discovery and compare it with the bulb position on the vehicle. Some trims may use different LED assemblies or optional equipment, and aftermarket conversions can change fitment even when the light appears similar. If a bulb or lamp assembly has already been replaced, it is smart to inspect the installed part before ordering. That simple check can help you avoid mismatched connectors, incorrect housing styles, or buying a bulb that fits one version of the 2021 Discovery but not another.
