OEM Part Number: confirm via VIN — aftermarket LH Hella 1EG 354 837-011 / RH Hella 1EG 354 837-021

Accuracy note: Covers the Audi A1 (8X 2010-2018) 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 1EG 354 837-011 (halogen H7/H1, with DRL, electric levelling motor, bulbs included); Hella 1EG 354 838-011 (halogen H7, W5W, H15, with DRL, motor); Van Wezel 0301961 (halogen H7/H1, no DRL, electric levelling); Van Wezel 0304961 (facelift, halogen H15/H7, with DRL, electric levelling); Alkar 2751467 (halogen H15/H7, electric levelling motor); Hella 1EL 354 838-051 (bi-xenon D3S, LED DRL, no levelling motor)
Driver's side (RH / offside) headlight — aftermarket	Hella 1EG 354 837-021 (halogen H7/H1, with DRL, motor, bulbs included); Hella 1EG 354 838-021 (halogen H7/H15, with DRL, motor); Van Wezel 0301962 (halogen H7/H1, no DRL, electric levelling); Van Wezel 0304962 (facelift, halogen H15/H7, with DRL, electric levelling); Van Wezel 0301986 (xenon D3S, automatic levelling, no control unit); Hella 1EL 354 838-061 (bi-xenon D3S, LED DRL)

Fitment notes	Halogen is the common fit; D3S xenon and bi-xenon units with LED DRL exist for xenon cars; facelift cars use H15 DRL units (Van Wezel marks 0304961/0304962 "for facelift").

A Genuinely Important UK Rule Worth Knowing Before You Buy — Audi A1 Headlights

If your A1 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.

Audi A1 Headlights: What It Does

Precise beam angling to light the road without dazzling oncoming traffic is the Audi A1's headlight unit's core job, housing the main and dipped beams — or LED/matrix modules on higher trims. Because it often also integrates the daytime running light and front indicator, both the part number and repair complexity increase accordingly.
