Placement on the front right side of the vehicle allows for the maintenance of the original sound signal system configuration, without the need for modifications to the wiring or brackets.

Such a fitment promotes stable horn operation, proper vibration dissipation, and the maintenance of the appropriate volume level and sound timbre, in accordance with the vehicle manufacturer's specifications.

Technical and functional characteristics

The horn generates a signal with a frequency of 420 Hz, which ensures a clear, easily recognizable sound in typical road conditions. The construction is adapted for operation in the front compartment, taking into account exposure to moisture, temperature changes, and road debris.

• Dedicated placement in the front zone – right side of the vehicle.
• Acoustics adapted to road requirements and the characteristics of Mercedes models.
