OEM Part Number: confirm via VIN — aftermarket LH Van Wezel 2791961 / RH TYC 20-11529-25-2

Accuracy note: Covers the Mazda CX-3 (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 2791961 (halogen H11/H15, DRL, electric levelling cars, no motor, not for facelift); Alkar 2741674 (halogen H15, H11, W5W); Abakus 216-1173L-LDEM2 (halogen H11/H15, W5W, no motor); Abakus 216-1166L-LD-EM (halogen H11, HB3, PY21W, W5W, electric); Alkar 2741652 (halogen H7/HB3, W5W, PY21W); Abakus 216-1158L-LDEM2 (halogen H11/HB3, yellow indicator)
Driver's side (RH / offside) headlight — aftermarket	Van Wezel 2791962 (halogen H11/H15, DRL, electric levelling cars, no motor, not for facelift); Diederichs 5645080 (halogen H11/H15, DRL, levelling cars, no motor); Alkar 2742674 (halogen H15, H11, W5W); TYC 20-11529-25-2 (halogen H11/H9, electric levelling, no motor); Alkar 2742652 (halogen H7/HB3, W5W, PY21W, electric); Abakus 216-1158R-LDEM2 (halogen H11/HB3, electric)
Bulb types	dipped H11, daytime running H15; alternative H7/HB3; indicator PY21W; sidelight W5W; H4 on basic units
Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine units against your VIN
Fitment notes	Every unit listed is halogen with no LED or xenon option; the Van Wezel and Diederichs H11/H15 units include a DRL function, and the Van Wezel units are not for the facelift.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Mazda CX-3 Headlights

If your CX-3 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.

Mazda CX-3 Headlights: What It Does

On the Mazda CX-3, the main and dipped beams, whether conventional bulbs or LED/matrix modules on higher trims, sit inside the headlight unit at an angle calculated to illuminate the road without dazzling other drivers. Many modern units also combine the daytime running light and indicator into that same housing, adding a layer of complexity to both part numbers and repairs.

Mazda CX-3 Headlights: Generations & Headlight Type

Standard trims	Halogen as standard on entry trims
Sport/higher trims	Full LED headlights with automatic on/off become available, genuinely a different assembly and connector from the halogen units on lower trims — not a simple bulb swap
