OEM Part Number: confirm via VIN — aftermarket LH TYC 20-12372-05-2 / RH TYC 20-12371-05-2

Accuracy note: Covers the Hyundai ix35 (2010-2015) 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	Van Wezel 8262963 (halogen HIR2, LED DRL, for electric-levelling cars); Diederichs 6861183 (halogen HIR2, LED DRL); TYC 20-12372-05-2 (halogen H7/H7, electric levelling motor included); Van Wezel 8257961 (halogen H7/H7); Diederichs 6861081 (halogen H7/H7); Alkar 2751582 (LED with HIR2, electric levelling)

A Genuinely Important UK Rule Worth Knowing Before You Buy — Hyundai ix35 Headlights

If your ix35 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.

Hyundai ix35 Headlights: What It Does

The Hyundai ix35'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.
