Used Hyundai i30 Brake Light Switch

The i30 moved from its first generation (roughly 2007–2012) to the second generation (2012–2017) part-way through that span, and the brake light switch design changed with it, so a 2012 switch may or may not cross over depending on exactly which generation each car is. Confirm the generation of both cars with your breaker against your registration before buying, as fitting the wrong switch can prevent the brake lights working or cause gearbox interlock faults on automatics. Never assume year-to-year compatibility across a generation change.

For the brake light switch, engine size makes no meaningful difference — the switch sits on the brake pedal assembly and operates the same way across petrols and diesels in the same generation. What matters is the generation of the car, not whether you have a 1.4, 1.6 petrol or 1.6 diesel under the bonnet. As long as the breaker's part comes from the same generation i30 as yours, engine size is not a concern here.

Trim level has no effect on brake light switch fitment — whether your i30 is a Classic, Active, Comfort, Style or Premium, the switch on the brake pedal is identical within the same generation. There are no cosmetic or performance trim differences that change the pedal box or switch specification. Simply match the generation and you can disregard the trim badge entirely.

Yes, every Hyundai i30 across all generations and all variants has a brake light switch — it is a standard fitment on any road car sold in the UK, required for the brake lights to function and, on automatic gearbox models, for the shift interlock system. There is no drivetrain or engine variant of the i30 that would ever omit this part. If your brake lights are staying on or not coming on at all, a faulty brake light switch is a very common cause and a used unit from a breaker is a straightforward fix.

The first-generation i30 ran from around 2007 to 2012 and the second generation from 2012 to 2017, and these are distinct platforms with different pedal assemblies, so the brake light switch from a first-gen car is unlikely to be a direct fit on a second-gen model. Confirm the exact part against your registration with your breaker before ordering, as the switch connector and mounting clip design can differ between generations. Do not assume interchangeability across this generation boundary.

The third-generation i30, which arrived in 2017, is again a new platform and the pedal box components were revised, so a switch from a 2012–2017 car should be treated as a different application. Confirm compatibility with the breaker by quoting your exact registration, as even if the part looks similar the connector or plunger length may differ. Fitting an incorrect switch risks brake lights that fail to illuminate or illuminate continuously, so it is worth taking the time to verify.
