How loud is this horn and when would I use it?

The HK horn reaches up to 150 dB at peak output, producing a powerful tone intended to alert other road users or signal in noisy environments. It’s suitable for heavy vehicles, off-road use, and marine applications where extra acoustic presence is helpful.

• Rated peak output: up to 150 dB for strong auditory presence
• Dual trumpet design for a layered, attention-grabbing tone
• Works well in heavy-traffic, construction zones, and open-water situations

What makes the compressor and trumpets durable?

This kit uses chrome-plated zinc alloy trumpets and a compressor built with an enlarged coil and all-copper wiring elements to withstand repeated use. The materials are selected to tolerate exposure to road grime and variable weather, extending service life compared with cheaper plastic horns.

• All-copper coil and zinc alloy parts improve longevity under harsh conditions
