Mitsubishi ASX Headlights: OEM Part Number

Accuracy note: genuinely worth knowing: ASX headlights are frequently revised at a mid-generation facelift, changing the internal lens design and light signature even where the exterior shape looks similar — confirm your exact build date, not just generation, before ordering.

A Genuinely Important UK Rule Worth Knowing Before You Buy — Mitsubishi ASX Headlights

If your ASX 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.

Mitsubishi ASX Headlights: What It Does

Inside the Mitsubishi ASX's headlight unit sit the main and dipped beam bulbs, or LED/matrix modules on higher trims, precisely angled to light the road ahead without dazzling oncoming drivers. Many current units also fold the daytime running light and front indicator into the same housing, which complicates both the part number and any repair.
