Peugeot 308 Headlights: OEM Part Number

Accuracy note: genuinely worth knowing: adaptive or matrix LED headlights on higher 308 trims are significantly more expensive to replace than standard units and often can't be sourced secondhand as easily — worth checking whether your car has this feature (usually badged or listed in the spec sheet) before assuming a standard-trim price applies.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Peugeot 308 Headlights

If your 308 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 308 Headlights: What It Does

On the Peugeot 308, main and dipped beam bulbs — or LED/matrix modules on higher-spec cars — live inside the headlight unit, angled carefully to illuminate the road without blinding oncoming traffic. The daytime running light and front indicator often share that same housing too, adding complexity to both fitment and repair.

Peugeot 308 Headlights: Generations, Derivatives & Headlight Type

Pre-2011	Halogen (H7 reflector) or Bi-Xenon depending on trim — both technologies are now known to suffer reflective-layer degradation with age, causing dangerously low light output on unrestored examples
Facelift (2011+), Allure	LED became available as a genuine factory option from this facelift onward
GT Line	Full LED headlights are standard, confirmed as a completely different, brighter design than the halogen or Bi-Xenon units on lower/older trims — full replacement units can cost around £1,000 each
