Bulb size chart
This page helps you verify the bulb sizes for the 2018 Land Rover Discovery by lighting position, so you can match the correct bulb to the right job before ordering. Whether you are replacing a headlight, a turn signal, or a small interior lamp, checking the location first makes it much easier to find the correct fit.
For the 2018 Land Rover Discovery, many exterior and interior lighting points use LED setups, including the headlight high beam and low beam, fog lights, brake lights, license plate lights, and cabin lights. Because bulb fitment can vary by market, trim, and body style, it is best to confirm the exact position on your vehicle before buying replacements.
Fitment on the 2018 Discovery can differ depending on trim, lighting package, and regional market, so do not assume every vehicle uses the same bulb in every position. Some versions may have factory LED lighting where others may use a different setup, and aftermarket LED conversions can change what is installed as well. If you are replacing a bulb, check the old bulb or the housing label before purchase, and compare the installed part to the listing for your specific lighting position. This is especially important for headlight, fog light, and rear lamp applications, where halogen-to-LED changes or previous owner modifications can affect compatibility.
