It should be taken into account that access to the screws for fastening the additional brake light is difficult. You can unscrew the screws with a Phillips screwdriver with a blade longer than 180 mm or a small ratchet with a removable tip.
Removal the lantern
1. Prepare the car for repair work.
2. Using a Phillips screwdriver, unscrew the three screws of the additional brake light to the spoiler.
3. Remove the brake light from the niche, disconnect the wire connectors and remove the additional brake light from the car.
Recommendation. The additional brake light is non-separable. If several LEDs stop lighting, the light must be replaced.
