Used Mercedes-Benz Vito Brake Light Switch

The Vito has run across three main generations: the W638 (1996–2003), the W639 (2003–2014), and the W447 (2014–present), and the brake light switch design changed between each of these generations as the pedal box and switch mounting points were redesigned. A W638 switch is very unlikely to be a straight swap onto a W639 or W447, so crossing that generation boundary is not something we can confirm here. Always give the breaker your full registration so they can check the part against your exact build.

The brake light switch on the Vito operates from the brake pedal mechanism rather than from the braking hardware itself, so engine size and payload or GVW rating do not typically affect which switch is fitted. The switch mounting is generally consistent across the engine and payload variants within the same generation. That said, always confirm with the breaker using your registration, as mid-generation revisions can occasionally affect small ancillary parts like this.

Trim levels such as Sport, Tourer, and Pro on the Vito do not affect brake light switch fitment, as the switch is part of the pedal assembly which does not change with trim specification. You may find cosmetic differences around the pedal area depending on interior trim, but the switch itself should be the same across trims within the same generation. Confirm the generation and build year with the breaker to make sure you are getting the right part.

A 2013 Vito is a late W639, while a 2015 Vito is an early W447 – these are different generations with a generation changeover in 2014, and the pedal box and associated components were redesigned at that point. We cannot confirm that a switch from one generation will fit the other, and crossing that boundary is exactly the kind of question to put directly to the breaker with both registrations to hand. Do not assume interchangeability across the W639–W447 boundary without the breaker verifying it.

Yes, all variants of the Mercedes-Benz Vito across every generation are fitted with a brake light switch, as it is a standard safety component required to illuminate the brake lights when the pedal is depressed. On the Vito it is typically mounted on the brake pedal bracket under the dashboard on the driver's side (NS in right-hand-drive UK vehicles). It is a commonly replaced wear item and used examples are regularly available from breakers.

The W639 Vito ran from 2003 to 2014 and received a facelift, with the updated model generally recognised from around 2010 onwards bringing changes to the exterior and some interior components. The brake light switch itself sits on the pedal bracket and was not a focus of the facelift changes, but small revisions to the pedal assembly cannot be ruled out across such a long production run. To be safe, give the breaker your registration and ask them to confirm the part matches your specific build year rather than assuming all W639 switches are identical.
