Second Hand Hyundai Tucson Brake Light Switch

Yes, the brake light switch is a real part on the Hyundai Tucson — it sits on the brake pedal bracket and tells the brake lights to illuminate when you press the pedal, and it also communicates with systems like cruise control and the ABS module. Every Tucson variant, regardless of engine size or drivetrain, has one. It is one of the most universal parts on any modern car.

These fall into two different generations — the second-generation Tucson (known in some markets as the ix35 replacement) ran from 2015 onwards, while the 2013 model sits in the first-generation (TL predecessor) range, so the pedal box design and connector are likely different. You should not assume these will interchange across that generation boundary. Confirm with the breaker against your exact registration before ordering.

The brake light switch itself sits on the brake pedal assembly and is not directly determined by whether the engine is petrol or diesel — it performs the same function regardless of engine type. In practice the same switch design is typically used across the engine range within a given generation. That said, confirm the part number with the breaker against your registration to be certain, as connector designs can vary between model years.

Trim level does not affect brake light switch fitment — the switch operates the brake lights and interacts with pedal-mounted systems in the same way across all trim levels. You may find cosmetic differences around the pedal box area depending on trim, but the switch itself is not trim-dependent. Stick to matching the correct generation rather than worrying about whether a part came from an S or a Premium car.

The third-generation Tucson (TL) ran from 2015 with a facelift around 2018-2019, so a 2016 and a 2019 car are both within the same generation but sit either side of that facelift point. The brake light switch may well be the same unit across this period, but whether the connector and bracket are identical across the facelift is something to confirm with the breaker against both registrations before buying.

Make sure the breaker can match the part to your registration plate, as this is the most reliable way to confirm the correct generation and connector type. It is also worth checking the connector pin configuration visually against your old switch if possible, as these small differences can cause the part not to plug straight in. A reputable breaker on Findapart should be able to verify this for you before dispatch.
