Second Hand Mercedes-Benz CLA Brake Light Switch

Yes, every variant of the Mercedes-Benz CLA has a brake light switch — it is a standard component on all petrol and diesel versions across both generations, as it signals to the brake lights and the ABS/ESP system when the pedal is pressed. There are no CLA variants where this part is absent.

The first-generation CLA (C117, 2013–2019) and the second-generation CLA (C118, 2019–onwards) are built on different platforms with different pedal box assemblies, so the brake light switch is unlikely to be a straight swap across that boundary. Name that generation boundary clearly to your breaker and confirm against your exact registration before ordering a used part.

Engine size and output do not typically affect the brake light switch itself, as it is a pedal-mounted electrical component rather than part of the braking hardware that varies with engine power. That said, always confirm the specific part number with your breaker against your registration, as there can be subtle electrical differences between variants.

The first-generation CLA received a facelift in 2016, but the brake light switch sits in the pedal box rather than in the areas updated during a facelift, so the refresh is unlikely to affect which switch fits. To be safe, give your breaker your full registration so they can verify the exact specification of your car.

Trim level does not affect the brake light switch; Sport, AMG Line, and Urban trims all share the same pedal box setup and this part is purely functional rather than cosmetic. You may notice cosmetic differences on other parts from a donor car with a different trim, but for the brake light switch itself trim is irrelevant.

The CLA Shooting Brake (X117) shares its platform with the C117 CLA saloon, so a brake light switch from a same-generation Shooting Brake may well be compatible, but confirm this with your breaker against both registrations. Cross-referencing with the A-Class (W176 or W177) is also worth asking a breaker about, as these models share architecture with the respective CLA generations, though fitment cannot be guaranteed without checking.
