Land Rover Discovery Headlights: OEM Part Number

Accuracy note: genuinely worth knowing: headlight type genuinely matters more than model name on the Discovery — halogen, HID/Xenon, and LED (including adaptive/matrix LED on higher trims) use entirely different housings that aren't interchangeable, and swapping bulb type without swapping the housing isn't legal or safe. Confirm which your car has via the badge, owner's manual, or by looking at the unit itself before ordering.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Land Rover Discovery Headlights

If your Discovery has factory-fitted halogen headlamp housings, converting them to fit LED bulbs is treated as a definite MOT failure under the current inspection manual — this isn't a grey area or a minor advisory, since a housing designed for halogen doesn't distribute an LED bulb's light output correctly, which can genuinely dazzle oncoming drivers. If you want a genuine LED upgrade, the correct route is a complete headlight unit designed for LED from the factory, not a bulb swap into an existing halogen housing.

Before you buy: matrix LED, adaptive, and cornering headlight systems often require electronic coding to the car after a unit swap, even for a genuine like-for-like replacement — a headlight that isn't recognised by the car's electronics can trigger warning lights or fail to auto-level correctly. Check whether your specific trim has one of these systems before assuming a straightforward bulb-in, bulb-out job.

Land Rover Discovery Headlights: What It Does

The Land Rover Discovery's headlight unit houses the main and dipped beam bulbs (or LED/matrix modules on higher trims), positioned and angled to illuminate the road ahead without excessively dazzling oncoming traffic. Many modern units also integrate the daytime running light and front indicator into the same housing, which affects both the part number and the complexity of any repair.

Land Rover Discovery Headlights: Generations, Derivatives & Headlight Type

Standard trims	Halogen as standard on older generations, with LED becoming the norm on newer models
Higher trims (HSE/Autobiography)	Full LED or Adaptive LED (Matrix on the newest generations) becomes available — genuinely non-interchangeable with the halogen or standard LED units on lower trims, requiring matching control modules and wiring to retrofit
