Ever find that your factory horn is too quiet? 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.
These horns may not be a bolt on option for your vehicle. Some wiring and or mounting brackets may be needed in order to fit these horns onto your vehicle.
