OEM Part Number: confirm via VIN — aftermarket LH Valeo 046898 / RH Valeo 046901

Accuracy note: Covers the Volvo XC90 (2015-) as listed in the UK aftermarket catalogues. Headlights are sold by side (passenger / nearside = LH, driver's / offside = RH on a UK car) and by lamp type — halogen, xenon (D1S / D3S) and LED or full-LED units are not interchangeable, and DRL, cornering and levelling options change the part number again. The references below are UK aftermarket catalogue listings for this generation, labelled by brand; genuine numbers are shown only where a listing quotes one. Check the lamp type and traffic side (UK right-hand-traffic units, not LHD) against your VIN, and expect xenon / LED and adaptive units to need levelling adjustment or coding after fitting.

Passenger side (LH / nearside) headlight — aftermarket	TYC 20-17922-05-2 (halogen H7/H9 with W21/5W, DRL, electric levelling with motor); Prasco VV7104904 (halogen H7/H7); Diederichs 7685081 (halogen H7/H7, electric levelling, without motor); Alkar 2741519 (halogen H7/H7 with H21W, electric levelling); Valeo 046898 (xenon, motor, no control unit, dynamic bending light); Johns 90 91 09-2 (halogen, with indicator, no motor).
Driver's side (RH / offside) headlight — aftermarket	TYC 20-17921-05-2 (halogen H7/H9 with W21/5W, DRL, electric levelling with motor); Prasco VV7104903 (halogen H7/H7); Diederichs 7685080 (halogen H7/H7, electric levelling, without motor); Alkar 2742519 (halogen H7/H7 with H21W, electric levelling); Valeo 046901 (xenon D1S, motor, no control unit, dynamic bending light); Valeo 046899 (xenon, motor, no control unit, dynamic bending light)

A Genuinely Important UK Rule Worth Knowing Before You Buy — Volvo XC90 Headlights

If your XC90 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.

Volvo XC90 Headlights: What It Does

On the Volvo XC90, main and dipped beam bulbs — or LED/matrix modules on higher-spec cars — live inside the headlight unit, angled carefully to illuminate the road without blinding oncoming traffic. The daytime running light and front indicator often share that same housing too, adding complexity to both fitment and repair.

Volvo XC90 Headlights: Generations & Headlight Type

Older/pre-Thor's Hammer generations	Halogen or Xenon depending on trim, in a conventional headlight shape
Current generation, all trims	Genuine "Thor's Hammer" T-shaped LED daytime running light signature, first introduced on the second-generation XC90 in 2015 and now a defining Volvo design cue; automatic high beam and active bending lights are included
Reliability note	Thor's Hammer units are LED-based sealed assemblies rather than serviceable bulbs — documented failures include water ingress once seals age, and Volvo's own warranty terms have reportedly excluded this as "wear and tear"; full unit replacement can run into four figures per side
