Compact 12V train horn

The RAYBESTOS UNBRANDED 300DB Super Train Horn is a 12-volt audio accessory designed for trucks, SUVs, cars, boats and motorcycles. Its single-piece construction integrates a mini-compressor with a patented snail horn, measuring approximately nine centimetres in diameter and depth. The unit mounts discreetly and includes all hardware for a sub-hour installation.

300DB output and headroom

Rated at 300DB loudness coefficient, the horn produces a deep, train-like tone at 510HZ that carries well in traffic and off-road situations. A single horn satisfies most drivers wanting maximum presence, while the compact footprint allows a second unit to be added where mounting space permits. The 12-volt draw is modest, so the factory electrical system typically handles one or two horns without upgrades.

E-mark 510HZ constraint

The horn carries an E-mark rating at 510HZ, confirming compliance for road use in regions that recognise the standard. Output is fixed at this frequency, so users cannot adjust pitch or volume electronically. Buyers needing variable tones, programmable patterns or integration with CAN-bus lighting controllers will find this analogue device does not support those functions.

How can I confirm the 300DB horn is functioning correctly after installation?

Activate the horn and listen for a loud, clear, deep train-like tone at the rated 510HZ frequency.

What components are included in the box and what must I purchase separately?

The kit includes the horn unit with integrated mini-compressor, mounting hardware and instructions; no extra parts are required for a standard 12 V installation.
