OEM Part Number: confirm via VIN — aftermarket LH Valeo 450516 / RH Valeo 450517

Accuracy note: Covers the Volkswagen T-Roc (2017-) 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	Valeo 450516 (halogen, electric levelling, bulbs for low beam, high beam and indicator); Valeo 450520 (LED low/high beam and indicator, optional LED DRL, electric levelling, no bulbs); Valeo 451068 (LED with LED DRL, no bulbs); Van Wezel 5710961V (halogen H7/H7, electric levelling, OES); Van Wezel 5710981V (LED, electric levelling, no control unit, OES); Van Wezel 5715981V (LED, facelift, electric levelling, no control unit)
Driver's side (RH / offside) headlight — aftermarket	Valeo 450517 (halogen, pair to 450516); Valeo 450521 (LED, pair to 450520); Valeo 451069 (LED with LED DRL, pair to 451068); Van Wezel 5710962V (halogen H7/H7, electric levelling, OES); Van Wezel 5710982V (LED, electric levelling, no control unit, OES); Van Wezel 5715982V (LED, facelift, electric levelling, no control unit)
Bulb types	dipped/main H7/H7 on halogen units, LED units with no replaceable bulbs
Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine units against your VIN
Fitment notes	Halogen H7/H7 and LED versions are both listed with no xenon, and the Van Wezel 5715981V and 5715982V pair is the facelift-specific LED unit; LED units are sold without the control unit.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Volkswagen T-Roc Headlights

If your T-Roc 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.

Volkswagen T-Roc Headlights: What It Does

Inside the Volkswagen T-Roc's headlight unit sit the main and dipped beam bulbs, or LED/matrix modules on higher trims, precisely angled to light the road ahead without dazzling oncoming drivers. Many current units also fold the daytime running light and front indicator into the same housing, which complicates both the part number and any repair.

Volkswagen T-Roc Headlights: Generations, Derivatives & Headlight Type

Standard trims	Halogen headlamps as standard
Design/R-Line, factory option	Standard LED, badged "IQ" on the unit itself — genuinely NOT the same as full IQ.Light Matrix, despite the shared "IQ" name
IQ.Light Matrix (factory option)	Genuine adaptive LED matrix system offering dipped/main beam control, dynamic curve lighting, and High Beam Assist — a paid option rather than a trim-included feature, confirmed not standard even on R-Line
