Peugeot 508 Headlights: OEM Part Number

Accuracy note: genuinely worth knowing: adjusting headlight aim correctly after replacement matters on the 508 as much as sourcing the right part — many replacement units ship in a default position that needs recalibrating, and getting this wrong can genuinely dazzle other road users even with a technically correct part fitted.

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.
