OEM Part Number: confirm via VIN — aftermarket LH Valeo 045290 / RH Valeo 045291

Accuracy note: Covers the Dacia Logan MCV (2013-2020) 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	Valeo 045290 (original part, halogen H4 with DRL); Van Wezel 1520961V (halogen H7/H7 with LED DRL, OES made by Valeo, electric levelling motor); TYC 20-17586-06-2 (H7/H7 with LED DRL, mechanical levelling, with adjuster); TYC 20-14612-05-2 (halogen H4 and W21/5W, mechanical levelling); Diederichs 4456181 (halogen H7/H7 with LED DRL and PY21W); Van Wezel 1507961 (halogen H4 with DRL, electric levelling, no motor, not for facelift)
Driver's side (RH / offside) headlight — aftermarket	Valeo 045291 (original part, halogen H4 with DRL); Van Wezel 1520962V (halogen H7/H7 with LED DRL, OES made by Valeo, electric levelling motor); TYC 20-17585-06-2 (H7/H7 with LED DRL, mechanical levelling, with adjuster); TYC 20-14611-05-2 (halogen H4 and W21/5W, mechanical levelling); Diederichs 4456180 (halogen H7/H7 with LED DRL and PY21W); Van Wezel 1507962 (halogen H4 with DRL, electric levelling, no motor, not for facelift)

Fitment notes	Pre-facelift cars have H4 halogen lamps and facelift cars have H7 halogen lamps with LED DRL, so check the car's age; Van Wezel 1507961 and 1507962 are marked not for facelift; no xenon is listed.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Dacia Logan MCV Headlights

If your Logan MCV 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.

Dacia Logan MCV Headlights: What It Does

On the Dacia Logan MCV, 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.
