Vixen Horns VXH3418B 3-Trumpet Train Horn Review (2026)

Methodology

This review aggregates publicly available information from manufacturer specifications, retailer listings, and verified user reviews. We do not perform hands-on testing. Last reviewed September 26, 2026. For the Vixen Horns VXH3418B we relied on Vixen’s official product page (construction, included items, dimensions, price), the product JSON Vixen’s store publishes for the same listing (listed weight), Vixen’s chrome, covers, and full-kit listings for the same horn, Vixen’s published warranty policy, and the Amazon listing for retail availability. Vixen publishes no decibel, PSI, frequency, or trumpet-length figures for this model, and we do not substitute numbers from other horns. Where something is not disclosed, the spec table says so.

Quick verdict

The VXH3418B is Vixen’s “other” black triple-trumpet horn. It sells for almost exactly the same price as the better-known VXH3318B, but it has a longer, wider, and noticeably lower-profile cluster: 19¼” × 18” × 7½” against the 3318B’s 16¼” × 15” × 11”. The hardware story is the same as Vixen’s other metal horns: an all-metal build, a 12V solenoid with a compression fitting, a 6-foot hose, mounting hardware, and a published 12-month warranty. The spec sheet is thin, though. There is no dB rating (which at least means no inflated one), no PSI recommendation, and no chord frequencies, so you are buying on construction, footprint, and the official sound clip rather than on numbers. We rate it 3.6/5. It’s a sensible choice for builders who already run onboard air and have a long, shallow mounting area.

What it is

The VXH3418B is a horn-only, three-trumpet train air horn with a black finish. Three trumpets of different lengths sit on a common base rail and share a single 12V electric air valve (solenoid). Vixen describes it as “made entirely of metal for maximum protection against all weather conditions” and says it “produces a loud roaring sound.” That description is marketing copy, not a measurement.

It is not a complete system. There is no compressor, air tank, pressure switch, or horn button in the box, and Vixen’s own listing ends with “Onboard Air System Required.” That makes it a good fit for trucks, Jeeps, and RVs that already carry air (air suspension, an existing horn tank, or a Vixen onboard-air kit bought separately), and a poor fit for anyone who wants one box that makes noise the day it arrives. For that buyer, Vixen sells the same horn bundled with a tank and compressor (see below).

The same horn comes in three versions on Vixen’s store:

• VXH3418B: black, the model reviewed here
• VXH3418C: chrome-plated, otherwise identical listing text and dimensions
• VXH3418B/P: black with three trumpet covers added

What’s in the box

According to Vixen’s listing, the VXH3418B ships with:

• Triple-trumpet train air horn (black), assembled on its base
• 12V electric air valve (solenoid) with compression fitting
• ¼” OD nylon plastic air hose, 6 feet
• Mounting hardware (bolts, washers, nuts)

Not included: compressor, air tank, pressure switch, safety valve, gauge, horn button, relay, fuse, or wiring. If you don’t already have an air source, the cheapest official route is one of Vixen’s bundles. At the time of review, the VXO8560/3418B (2-gallon tank, 150 PSI compressor) was listed at $388.87, the VXO8330/3418B (3-gallon tank, 200 PSI compressor) at $390.97, and the VXO4830AB/3418B (3-gallon aluminum tank, 200 PSI compressor) at $552.07. The VXO4830AB kit adds a pressure gauge, a 170–200 PSI pressure switch, a 250 PSI safety valve, a drain valve, extra hose, thread sealant, and a horn button.

Pros

• All-metal build at about $156. Vixen lists it as metal construction throughout.
• Low 7½” profile. It is about 3½” shorter in height than the VXH3318B, which helps under beds, behind bumpers, and on frame rails with limited vertical clearance.
• Solenoid with compression fitting included, so you only need to run air to one inlet and wire one 12V trigger.
• Published warranty. Vixen states a 12-month repair-or-replace warranty for the original purchaser.
• Official sound clip. Vixen hosts an MP3 demo on the product page (the file is named for the chrome VXH3418C), so you can hear the chord before buying.
• Clear upgrade path. Chrome, covered, and full-kit versions of the same horn are all sold directly by Vixen.

Cons

• No acoustic data at all: no dB rating, no test distance, no PSI recommendation, no chord frequencies. The Amazon title only promises “Super Loud dB.”
• Horn-only. A compressor and tank add roughly $230–$400 to the project, going by the gap between Vixen’s bundle prices and the bare-horn price.
• Large footprint. At 19¼” long and 18” wide it needs more flat area than the VXH3318B or VXH4318, both listed at 16¼” × 15”.
• Thin supplied air line. The included ¼” OD hose is fine for short runs but limits flow on longer or high-volume builds (see our air line size guide).
• Warranty exclusions. Coverage excludes improper installation and “rough contact to the elements,” and the buyer pays shipping on claims.

Alternatives

• Vixen Horns VXH3318B: the closest alternative. It is also a black, all-metal triple with a 12V solenoid, 6-foot hose, and hardware, at a nearly identical $155.27 direct price. The cluster is more compact at 16¼” × 15” but taller at 11”. Choose it if your mounting area is short but has vertical room.
• Vixen Horns VXH4318: Vixen’s heavy-duty chrome quad at $198.27 direct (black VXH4318B at $194.17). A fourth trumpet costs about $40 more, with the same air-system requirement.
• Kleinn 230: a triple from a brand with more detailed documentation, typically at a higher price than Vixen.

Install / compatibility notes

Electrically, the VXH3418B works on any 12V vehicle. Mechanically, it is half of a system. A typical install involves:

1. An air source. Use a compressor and tank, or an existing onboard-air system. Vixen doesn’t publish a working PSI for the bare horn, but its official bundles for this horn pair it with 150 PSI and 200 PSI compressors and 2- to 3-gallon tanks. More stored air means longer blasts; see our air tank size guide and PSI explainer.
2. A mounting location. You need roughly 19¼” × 18” of flat, rigid surface. The low 7½” height suits frame rails, under-bed crossmembers, and behind-bumper spots. Angle the bells slightly down so water drains out. Our truck mounting guide covers common spots.
3. Air plumbing. Run the included 6-foot ¼” hose from the tank to the solenoid’s compression fitting. Longer runs need more line and ideally a larger diameter.
4. Wiring. Trigger the 12V solenoid through a relay and an inline fuse from a horn button or a switched source. See our relay wiring guide.
5. A leak check before road use. Soap-test every fitting at full tank pressure.

Before you mount it, check local rules. Train horns are legal to own almost everywhere in the US, but using one on public roads often is not. Start with our are train horns legal on cars guide. For the full process, see how to install a train horn.
