Cheap Mercedes-Benz GLA Rear Light

Yes, generation matters completely for rear lights. The GLA has two distinct generations: the first-generation X156 ran from 2014 to 2020 (with a facelift in 2017), and the second-generation H247 launched in 2020 onwards – rear lights between these two generations are not interchangeable. Within the X156, whether a pre-facelift (2014–2016) unit crosses to a post-facelift (2017–2020) car is a boundary you should confirm with the breaker against your registration, as pressing and lens changes can affect the fit.

This question spans the 2017 facelift boundary within the first-generation X156, so the answer isn't straightforward. Both years sit within the same X156 generation, but the 2017 facelift brought styling updates that may have changed the rear light design and fixings. Name both registration plates to the breaker and ask them to cross-reference before buying – don't assume a 2016 unit will simply plug in to a 2018 car.

Trim level does not affect rear light fitment on the GLA; Sport, AMG Line, and other trim grades use the same rear light units within the same generation and facelift period. You may find that higher-spec cars have LED clusters where lower trims had conventional bulb units, so the cosmetic appearance can differ even if the mounting points are the same. Confirm the lamp type (LED vs bulb) matches your existing setup, but don't be put off a part simply because it came from a different trim level.

The GLA is a five-door crossover-SUV and that is the only body style it was sold in throughout both generations, so body style variation isn't a concern specific to this model. What does matter is generation: stick to X156 (2014–2020) or H247 (2020–present) parts as appropriate to your car. If a breaker mentions a related model from the same platform, confirm with them whether the rear light actually interchanges, as platform-sharing doesn't guarantee panel-for-panel compatibility.

Yes – nearside (NS, passenger side, left) and offside (OS, driver side, right) rear lights are mirror images of each other and are not interchangeable. Always specify which side you need when requesting a quote, and double-check the breaker's listing confirms the correct side before agreeing a price. Mixing them up is one of the most common and easily avoided mistakes when buying second-hand lights.

The GLA was sold in various markets, and while the fundamental body structure is shared, regional variants can have different rear light assemblies – for example, some markets used different indicator colours or lamp configurations. Whether a non-UK unit is a safe swap is something to confirm with the breaker against your specific registration, as wiring connectors and lens regulations can vary. A UK-sourced unit from a UK-registered car is always the safest starting point.
