OEM Part Number: confirm via VIN — aftermarket LH Valeo 450914 / RH Valeo 450915

Accuracy note: Covers the Vauxhall Adam (2013-2019) 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	Hella 1LR 010 117-211 (halogen H7/H1 with PY21W and W5W, no DRL, no motor); Magneti Marelli 710301214203 (halogen H7/H1, electric levelling); Magneti Marelli 710301262203 (halogen, W21/5W and PY21W, motor); Magneti Marelli 710301263207 (halogen, W21/5W and PY21W, motor); Valeo 450914 (halogen, bulbs included); Hella 1ZT 009 631-311 (bi-xenon D1S with H11, DRL, dynamic bending light)
Driver's side (RH / offside) headlight — aftermarket	Hella 1LR 010 117-221 (halogen H7/H1 with PY21W and W5W, no DRL, no motor); Magneti Marelli 710301214204 (halogen H7/H1, electric levelling); Magneti Marelli 710301263208 (halogen, motor); Valeo 450915 (halogen, bulbs included); Hella 1ZT 009 631-321 (bi-xenon D1S with H11, DRL, dynamic bending light); Hella 1ZT 010 012-421 (bi-xenon D1S with LED and H11, DRL, motor)

Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine units against your VIN
Fitment notes	Mainly halogen, with bi-xenon and a full LED unit at the top of the range; LED daytime running lights appear on some halogen units, and the fitment against the Adam should be confirmed by trim.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Vauxhall Adam Headlights

If your Adam 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.

Vauxhall Adam Headlights: What It Does

On the Vauxhall Adam, 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.
