Vauxhall Astra Headlights: OEM Part Number

Accuracy note: genuinely worth knowing: left-hand-drive and right-hand-drive Astra headlights have a different internal beam pattern to avoid dazzling oncoming traffic — a headlight sourced from the wrong market variant will fit physically but throw the beam in the wrong direction, which is both illegal and dangerous to use.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Vauxhall Astra Headlights

If your Astra 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.

Vauxhall Astra Headlights: What It Does

The Vauxhall Astra's headlight unit job is positioning the main and dipped beam bulbs (or LED/matrix modules on higher trims) to light the road without dazzling oncoming drivers. That housing frequently also contains the daytime running light and front indicator, which is exactly why part numbers and repairs here can get complicated.

Vauxhall Astra Headlights: Generations, Derivatives & Headlight Type

Standard trims	Halogen as standard
SRi and higher	Full LED headlights available
Higher trims, IntelliLux option	Genuine award-winning IntelliLux LED Matrix system — 16 LED segments (8 per side) that automatically fade out sections of the main beam around detected traffic, allowing permanent high beam; replacement is unit-only (no serviceable bulbs) and genuinely expensive — around £935+VAT for a full lamp versus under £15 for a standard halogen bulb
