Hella Stark Sound Twin Horn Set — Red 12V High/Low 118 dB Dual-Tone, Compact

Hella Stark Sound 109.23.37 is a red 12 V high/low frequency twin horn set that delivers a loud, attention-grabbing 118 dB signal for passenger vehicles.

This compact horn pair combines a high and a low tone to create a full, penetrating sound profile suitable for modern cars and light commercial vehicles. Built to Hella's manufacturing standards, the set includes two horns with blade connectors, ECE certification, and durable weather protection. Before fitting, confirm compatibility with your vehicle using your registration documents or the seller's vehicle verification service.

How does this Hella horn produce a stronger sound than single-tone units?

The Stark Sound set uses two separate diaphragms tuned to 300 Hz and 500 Hz so the tones blend into a richer, more noticeable signal. Pairing high and low frequencies improves perceived loudness and helps the sound cut through different traffic conditions without modifying the vehicle's electrical system.

• Measured sound level: 118 dB(A)
• Combined power draw: 66 W at 12 V

How easy is the installation and what electrical needs apply?
