OEM Part Number: confirm via VIN — no aftermarket tail light listed for this generation

Accuracy note: Covers the Land Rover Discovery (Discovery 5 2017-) as listed in the UK aftermarket catalogues. Tail lights are handed (left and right are different parts) and the right one depends on whether your car has bulb or LED units, whether the cluster comes with its bulb holder, the body style and the facelift date. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives, and shown for the left-hand light with its right-hand pair where the catalogue names one. Carmakers rarely publish the genuine number against these, so order a genuine light against your VIN if you want a guaranteed match; if the unit on your car has a separate inner light on the tailgate, that is sold as its own part.

Genuine (OE) numbers quotedNone quoted in the catalogue listings — the genuine light varies by trim, bulb or LED type and facelift date, so order it against your VIN
Fitment notesLeft and right are separate parts; check LED or bulb type, whether the bulb holder is included, body style and facelift date before ordering.

Land Rover Discovery Tail Lights: More Wiring Behind There Than Most People Assume

The Land Rover Discovery's tail lights pack brake, indicator, reversing and rear fog functions into a single unit, so a fault in the wiring or housing can affect several of them simultaneously — meaning "the tail light's broken" could describe quite different underlying problems.

Before you buy: tail light design and bulb type vary by trim and facelift status. Always confirm against your VIN before ordering.

Land Rover Discovery Tail Lights: What It Does

Beyond basic rear visibility, tail light units on the Discovery typically integrate brake lights, indicators, reversing lights and rear fog lights into a single housing. Higher trims may use LED units with a distinct light signature, which are not interchangeable with standard halogen units even if the physical mounting looks similar.

Land Rover Discovery Tail Lights: Generations & Tail Light Type

Standard trimsHalogen bulb-based units as standard
Higher trims, later model yearsLED tail lights become available further up the range, genuinely a different assembly and connector from the halogen units on lower trims

Tail light design changed between generations of the Discovery, and facelifted versions within the same generation often use a revised light signature that isn't interchangeable with pre-facelift units. Always confirm the exact part for your specific model year before ordering. Whether you're sourcing a replacement tail lights for your Land Rover Discovery from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying, and confirm you're ordering the correct side — driver's side (RH in the UK) or passenger side (LH in the UK) — since these are not interchangeable.

A Genuinely Useful Piece of Context Worth Knowing About Condensation — Land Rover Discovery Tail Lights

If condensation has appeared inside a tail light, this is genuinely worth knowing: related Land Rover models are fitted with breathable membranes in the light housings, allowing internal air to match outside humidity, with a sudden temperature drop able to trigger visible condensation considered a normal characteristic rather than a fault.

A genuinely useful, real DIY fix worth knowing: drilling a small drain hole at a 45-degree angle into the solid black base of the housing has permanently resolved recurring condensation on related models, worth trying if condensation keeps returning.

It's also genuinely worth knowing that even if condensation eventually clears, permanent staining left on the inside of the lens afterward is still typically claimable under warranty.
