OEM Part Number: confirm via VIN — aftermarket LH Valeo 045440 / RH Valeo 045441

Accuracy note: Covers the Peugeot 508 (2011-2018) 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 045440 (halogen H7, bulb included, electric levelling motor, original part); Valeo 044527 (halogen H7, W5W, electric levelling motor, original part); Johns 57 48 09 (halogen H7, no motor); Diederichs 4244183 (halogen H7, for levelling cars, Depo/TYC); Van Wezel 4082961 (halogen H7, facelift, marked right-hand traffic); Valeo 045444 (LED low beam, electric levelling motor, original part)
Driver's side (RH / offside) headlight — aftermarket	Valeo 045441 (halogen H7, bulb included, electric levelling motor); Valeo 450955 (halogen H7 with PWY24W and LED DRL, facelift, electric levelling motor); Johns 57 48 10 (halogen H7, no motor); Diederichs 4244182 (halogen H7, for levelling cars, Depo/TYC); Van Wezel 4082962 (halogen H7, facelift, marked right-hand traffic); Valeo 045445 (LED low beam, electric levelling motor, original part)
Bulb types	dipped H7; sidelight W5W; indicator PWY24W; socket PX26d; no xenon bulbs listed
Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine units against your VIN
Fitment notes	Halogen H7 is the main fitment with LED units for upper trims and an LED DRL on the facelift (Valeo 450958 left, 450955 right); Van Wezel 4068961/4068962, 4082961/4082962 and 4082963V/4082964V are marked right-hand traffic, so avoid them for UK cars.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Peugeot 508 Headlights

If your 508 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.

Peugeot 508 Headlights: What It Does

Precise beam angling to light the road without dazzling oncoming traffic is the Peugeot 508'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.
