Seat Ateca Headlights: OEM Part Number

Accuracy note: genuinely worth knowing: adjusting headlight aim correctly after replacement matters on the Ateca 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 — Seat Ateca Headlights

If your Ateca 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.

Seat Ateca Headlights: What It Does

Precise beam angling to light the road without dazzling oncoming traffic is the Seat Ateca'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.

Standard trims	Halogen as standard on lower trims
Higher trims/FR	Full LED headlights become available, genuinely a different assembly and connector from the halogen units — not interchangeable without coding and an adapter
