What This Horn Helps Solve

  • Weak or faded horn output on BMW and MINI vehicles
  • Failed OE horn requiring electrical replacement
  • Inconsistent high-tone or low-tone signaling
  • Corrosion or moisture-related horn performance loss
  • Need for an ECE-approved replacement horn for service repair

Installation Notes

Use the included mounting brackets and step-by-step instructions for installation on supported applications. Verify the vehicle’s horn tone requirement before replacement, since some BMW and MINI models use separate high-tone and low-tone horns. Confirm 12V electrical compatibility, blade terminal connection style, and bracket mounting location before final assembly.
