The Hella Sharptone kit H31000001 is an extremlely loud universal horn kit that will give your vehicle a very unique loud horn sound that will get the attention of everyone in the area.
Hella Sharptones are horns made for getting the attention of other vehicles around you on the road. These horns use a combination of a low tone (300hz) and a higher tone (415hz) to project a powerful 115db tone. The sound level from these horns are geared towards highway driving. This kit is comprised of two Hella horn round units (Yellow and Blue in color). A generic mounting bracket is included for each horn, but may need to be modified to fit your application. A single horn relay is included with each kit, but is not needed for Volvo vehicles.
