A buyer's guide to used Mercedes-Benz GLS headlight

Fitment questions

What years does the Mercedes-Benz GLS share the same headlights?

The GLS has been sold in two generations in the UK: the first-generation X166, produced from 2016 to 2019, and the second-generation X167, which launched in 2020 and is still current. Within each generation, headlights are shared across the range, so a 2017 GLS and a 2018 GLS will use the same units. Always confirm the exact part against your registration with the breaker before buying.

Will a headlight from a 2019 GLS fit my 2020 GLS?

This crosses the generation boundary between the X166 (2016–2019) and the X167 (2020 onwards), and the two generations have entirely different front-end designs, so they are not compatible. A headlight from a 2019 model will not fit a 2020 or later GLS. Stick to sourcing from within the correct generation for your car.

Does it matter whether I get a headlight from a GLS 350d or a GLS 400d — will either fit my car?

Engine and drivetrain make no difference to headlight fitment on the GLS; the front-end panels are shared across all engine variants within a generation. A headlight pulled from a 350d will fit a 400d or any other engine variant of the same generation just the same. Focus on matching the generation (X166 or X167) and the light position (NS or OS) rather than the engine badge.

Do GLS AMG Line headlights differ from standard trim headlights — will they fit my car?

Trim level does not affect whether a headlight physically fits the GLS — the mounting points and panel design are the same across trim grades within a generation. However, you may encounter cosmetic differences between trim levels, such as chrome surrounds or different internal styling, so the appearance may not perfectly match the rest of your car's front end. Confirm the exact style of unit with the breaker so you know what to expect.

The GLS had a mid-life update — do pre- and post-update headlights interchange?

The X166 generation GLS received a mid-cycle update for the 2019 model year, which brought changes to the front end including the lights and grille. This means a pre-2019 headlight and a post-2019 headlight may look different and could differ in mounting or wiring. Whether a specific unit will physically interchange across that boundary is something you should confirm directly with the breaker against your registration number.

Does it matter if the headlight I'm buying is halogen rather than xenon or LED?

Within a GLS generation the mounting points are the same, but halogen, xenon, and LED headlight variants can differ in their wiring connectors, levelling mechanisms, and internal assemblies, so swapping between light technologies is not straightforward. Whether a different variant will work on your specific car is something you should confirm with the breaker and, if needed, your mechanic before purchasing. Never assume a headlight will simply plug in because it came from the same model year.
