Horn Set Midnight Black Twin Tone Hella

Volume : This is one of the main key performance indicators for a horn’s characteristics. HELLA has a wide product range of horns in the volume range of 108 dB(A) to 118dB(A)
Functional Principle : Horns are powered by the battery current signal, which is commonly handled by a voltage pulse sent from the steering wheel. The current signal is transferred to a relay, which transmits the entire control current, preventing voltage drops. As the horn is powered by the electric current, it forms a magnetic field, which attracts a metal core together with a steel diaphragm. This attraction causes vibrations, which are transformed by varying resonances in order to gain low or high tones.
Nominal Voltage : (1) 7 – 12 V: for automotive vehicles, agricultural machinery, construction machinery
