This page covers the bulb sizes for the 2001 Land Rover Discovery and is organized by lighting position so you can quickly verify the correct replacement for each lamp. Whether you are changing a headlight, a marker light, or an interior bulb, matching the bulb to the exact location helps avoid buying the wrong part.
The 2001 Discovery can use different bulb setups depending on trim, market, and body style, so it is smart to compare the chart with the bulb already installed in your vehicle. Use this guide to confirm the size for each exterior and interior light before you order replacements.
For the best fitment results, check whether your Discovery uses standard halogen bulbs or has been modified with LED or aftermarket conversion kits, since those changes can affect compatibility even when the socket looks the same. Trim and lighting package differences may also change the bulb used in certain positions, especially on imported vehicles or trucks with prior repairs. If you are replacing a bulb that has failed, remove the old one and read the base before purchasing, because the installed bulb is the most reliable reference when the vehicle history is unknown. This is especially useful for mixed lighting systems where the same model year may use different bulbs for similar positions.
