Volvo V40 Headlights: OEM Part Number

Accuracy note: genuinely worth knowing: V40 headlight units with condensation inside the lens are a common complaint, and it's not always a sign the unit needs full replacement — a failed seal can sometimes be resealed rather than requiring a new headlight, worth checking before assuming the whole unit is beyond repair.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Volvo V40 Headlights

If your V40 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.

Volvo V40 Headlights: What It Does

On the Volvo V40, 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.
