Second Hand Ford Fiesta Brake Light Switch

The Ford Fiesta Mk6 ran from 2002 to 2008, while the Mk7 (also called the sixth generation in some classifications) ran from 2008 to 2017 with a facelift in 2013 — the brake light switch design changed between these generations, so a switch from one is unlikely to be a straight swap for the other. The switch clips onto the brake pedal bracket, and pedal box assemblies differ enough across generations that cross-generation fitment is not reliable. Confirm with the breaker that the donor vehicle shares your exact registration before purchasing.

This question crosses the 2013 facelift boundary within the Mk7 generation (2008–2017), and while the facelift was primarily cosmetic, subtle changes to pedal box components mean the switch may or may not interchange cleanly. Rather than assume it will fit, confirm with the breaker by giving them both registrations so they can check the exact part numbers against the donor vehicle.

For the brake light switch specifically, engine size has very little practical bearing on fitment — unlike brake discs or calipers, the switch is mounted on the pedal box and operates the same way regardless of whether your Fiesta has a 1.0, 1.4, or 1.6 engine. The key factor is the generation of the car, as pedal box design is generation-specific. Stick to matching the switch to your Fiesta's generation rather than worrying about engine variants.

Trim level — whether your Fiesta is a base Edge, Zetec, Titanium, or ST — does not affect brake light switch fitment, as the pedal box and switch mounting are the same across the trim range within a given generation. You may find the breaker pulls the switch from a Zetec when you have a Titanium or vice versa, and that is perfectly fine. Just ensure the donor car is from the same generation as yours.

Yes, all Ford Fiesta variants — petrol, diesel, automatic, and manual — are fitted with a brake light switch as standard, as it is a fundamental safety component required to illuminate the rear brake lights when the pedal is depressed. On the Fiesta, it sits on the brake pedal bracket behind the dashboard on the driver's side (right-hand drive, so the NS footwell). It is a common wear or failure item and straightforward to source from a breaker.

The Fiesta Mk6 ran from 2002 to 2008, and within that generation the brake light switch is generally consistent, making a 2007 donor switch a reasonable candidate for a 2005 car. That said, minor mid-production changes can occasionally affect small components like this, so it is still worth giving the breaker both registrations to cross-reference part numbers before you commit.
