OEM Part Number: confirm via VIN — aftermarket LH Hella 1EL 354 803-051 / RH Hella 1EL 354 803-061

Accuracy note: Covers the Ford Fiesta (Mk7 2008-2017) 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.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Ford Fiesta Headlights

If your Fiesta 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.

Ford Fiesta Headlights: What It Does

On the Ford Fiesta, 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.

Ford Fiesta Headlights: Generations, Derivatives & Headlight Type

Standard trims	Halogen (H7 bulb typical) — note the bulb housing is genuinely H7 despite some manuals/parts listings referencing H11b; check the physical bulb before ordering
Titanium and higher	LED headlight units become available further up the range on later model years
ST	Genuine Bi-Xenon HID projector headlights are standard on the ST, not LED — a completely different technology from other Fiesta trims, not just a brighter halogen
