Description

With over 100 years of experience in acoustic devices, HELLA ensures a pleasant yet powerful harmonic sound that complies with strict ECE and OEM requirements. Featuring a robust construction and a 123mm diameter, this horn set operates at a nominal voltage range of 7-12V for automotive, agricultural, and construction machinery, and 7-24V for commercial vehicles. It delivers an impressive sound level of 105 to 118 dB(A) with a frequency response of 500/300 Hz. The current draw is a maximum of 5.5 Amp at 12V, making it an efficient yet powerful addition to your vehicle. HELLA recommends mounting horns in pairs for optimal performance and sound projection. The functional principle involves the battery current signal activating a relay, which powers the horn's electromagnetic coil. This creates vibrations that produce distinct low and high tones, characteristic of HELLA's advanced acoustic technology.
