Brake lights
Come on when the brake pedal is pressed. The rear electrical unit monitors the circuits to the brake lights and sends error messages to the bus.
The vehicle has a brake light in the right and left lighting clusters and a high-level brake light in the top of the rear screen. The high-level brake light is of the LED type. The brake light bulbs in the light clusters are of the filament type and combined with the parking lights. The brake light bulbs in the light clusters are supplied with a PWM voltage.
If a filament breaks in the lamp which normally serves as a brake light, the function is replaced by the parking light bulb next to it.
