OEM Part Number: confirm via VIN — aftermarket LH TYC 20-11928-15-2 / RH TYC 20-11927-15-2

Accuracy note: Covers the Toyota Avensis (T270 2009-2018) 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	Van Wezel 5420961 (halogen H11/HB3, electric, motor not included); Van Wezel 5421961 (halogen H11/H9, electric, no motor); TYC 20-11928-15-2 (halogen H11/HB3, motor included); Abakus 212-11P2L-LD-EM (halogen H11/HB3, electric); Van Wezel 5422963 (HIR2 LED facelift, black frame, no motor); Abakus 212-11AQL-LDEM2 (HIR2 LED with DRL, from 2015)

A Genuinely Important UK Rule Worth Knowing Before You Buy — Toyota Avensis Headlights

If your Avensis 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.

Toyota Avensis Headlights: What It Does

Inside the Toyota Avensis'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.
