Supertone 12V High/Low Twin Horn Kit with Red Grill - Distinctive

In this review of the Supertone 12V High Tone/Low Tone Twin Horn Kit the bottom line is simple: this is a compact, visually distinct horn kit for drivers who want a clear improvement over stock horns without complicated installation. It suits owners of cars and light trucks who value appearance as much as function, since the kit pairs a bold red protective grille with a black coated metal body. The review finds the horns deliver reliable close-range performance, are easy to fit, and come with a one year limited warranty, though sound level impressions vary among users.

Key Features

• Dual tone design: The combination of high tone and low tone produces a layered sound that cuts through typical traffic at close range.
• Durable construction: Black coated metal body and galvanised components resist corrosion and hold up to road conditions.
• Distinctive styling: The red protective grille gives a striking visual accent visible through many vehicle openings.
• Simple fitment: Compact twin horn kit and black holder make the unit straightforward to mount and wire to existing 12V systems.
• One year limited warranty: The included warranty provides basic peace of mind for the first year of ownership.

Who It's For

This kit is a good match for car and light truck owners looking to replace a weak factory horn with something that looks and sounds more purposeful. It is especially appealing to those who appreciate an aftermarket aesthetic element, since the red grille is visible and purposeful rather than purely utilitarian.

It is less suitable for buyers who need extremely high-volume long-range horns or those who expect an overwhelming air-horn level blast. Some users report mixed impressions of overall loudness, so enthusiasts seeking maximum dB output should consider specialist horn systems instead.

• Noticeable improvement over many stock horns with dependable close-range functionality.
• Galvanised metal and black coated body provide sensible corrosion resistance for exterior use.

Cons

Specifications
