OEM Part Number: confirm via VIN — aftermarket LH Valeo 046604 / RH Valeo 046605

Accuracy note: Covers the Skoda Fabia (Mk3 2014-2021) 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	Valeo 046604 (halogen H4, W5W, PY21W, with DRL, no levelling motor, original part); Hella 1EL 011 824-211 (halogen H7/H7, WY21W, LED DRL, levelling motor, supplied with bulbs); Hella 1LL 011 824-231 (halogen H7/H7, WY21W, LED DRL, levelling motor, supplied with bulbs); Diederichs 7807983 (halogen H7/H7, LED DRL, levelling motor, Depo/TYC quality); TYC 20-15032-06-2 (halogen H7/H7, LED DRL, electric levelling); TYC 20-19172-06-2 (LED, PWY24W, LED DRL, electric levelling)
Driver's side (RH / offside) headlight — aftermarket	Valeo 046605 (halogen H4, W5W, PY21W, with DRL, no levelling motor, original part); Hella 1EL 011 824-221 (halogen H7/H7, WY21W, LED DRL, levelling motor, supplied with bulbs); Diederichs 7807982 (halogen H7/H7, LED DRL, levelling motor, Depo/TYC quality); TYC 20-15031-06-2 (halogen H7/H7, LED DRL, electric levelling); TYC 20-15027-05-2 (halogen H4, P21W, with DRL, electric levelling); TYC 20-19171-06-2 (LED, PWY24W, LED DRL, electric levelling)

Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine units against your VIN
Fitment notes	Base cars use H4 halogen, mid-range cars H7 halogen with LED DRL, and the LED units (TYC 20-19171/20-19172, Diederichs 7807184/7807185) suit the facelift LED trim; no xenon is listed, and some Diederichs units are for cars built to 08/2018 or the facelift only.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Skoda Fabia Headlights

If your Fabia 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.

Skoda Fabia Headlights: What It Does

On the Skoda Fabia, 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.
