OEM Part Number: confirm via VIN — aftermarket LH TYC 20-17582-05-2 / RH TYC 20-14193-05-2

Accuracy note: Covers the Toyota Yaris (XP130 2011-2020) 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	TYC 20-17582-05-2 (halogen H4 with W21/5W, electric levelling with motor); Abakus 212-11BZL-LEMN2 (halogen HIR2 with WY21W and W21/5W, electric levelling, supplied without motor, 2017 onward); Alkar 2769268 (halogen HIR2 with WY21W and W21/5W); Van Wezel 5344963 (halogen HIR2, facelift, for electric levelling); Van Wezel 5428985 (halogen HIR2, pre-facelift, no motor or ballast); Johns 81 57 09-8 (halogen, with DRL, motor included).
Driver's side (RH / offside) headlight — aftermarket	TYC 20-14193-05-2 (halogen H4, electric levelling with motor); TYC 20-17581-05-2 (halogen H4 with W21/5W, electric levelling with motor); Van Wezel 5344964 (halogen HIR2, facelift, for electric levelling); Van Wezel 5428986 (halogen HIR2, pre-facelift, no motor or ballast); Alkar 2770268 (halogen HIR2 with WY21W and W21/5W); Johns 81 57 10-8 (halogen, with DRL, motor included).
Bulb types	dipped/main H4 (early and base cars) or HIR2 (facelift and higher-spec units), indicator PY21W or WY21W, W21/5W, sidelight W5W.
Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine units against your VIN
Fitment notes	Every unit is listed as halogen, with DRL stated only on the two Johns units; the facelift is split by Van Wezel 53449xx (facelift) against 54289xx (pre-facelift), and electric-levelling cars need the motor transferred from the old unit where a part is sold without one.

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

If your Yaris 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 Yaris Headlights: What It Does

Precise beam angling to light the road without dazzling oncoming traffic is the Toyota Yaris'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.

Standard trims	Halogen as standard, with LED daytime running lights integrated on many trims
Higher trims	LED headlights become available on higher trims and more recent generations, genuinely a different assembly from the halogen units on lower trims
