OEM Part Number: confirm via VIN — aftermarket LH TYC 20-15514-15-2 / RH TYC 20-15513-15-2

Accuracy note: Covers the Mazda CX-5 (KE 2012-2017) 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 20-15514-15-2 (halogen H11/H15, DRL, electric levelling cars, no motor); Van Wezel 2780961 (halogen H11/HB3, electric levelling cars, no motor); Diederichs 5630083 (halogen H11/HB3, DRL, no motor); Abakus 216-1166L-LEAN2 (xenon D4S, PY21W, W5W); Alkar 2765906 (LED, PY21W, electric motor); Prasco MZ7024914 (LED with LED DRL, motor)

A Genuinely Important UK Rule Worth Knowing Before You Buy — Mazda CX-5 Headlights

If your CX-5 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-5 Headlights: What It Does

Precise beam angling to light the road without dazzling oncoming traffic is the Mazda CX-5'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 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
