This mod reduces the volume of the reverse horn by creating the effect of putting a resistor between the cables. The sound will now be significantly quieter and more comfortable to hear.

Features:

Volume reduction: up to 30% of the original volume.
Application: works with all vehicles, including modified models with their own reverse sounds.
Convenience: reduces the harshness of the sound when using an external camera where the volume is usually higher.
