Vevor 4-Trumpet 6L Tank 150 PSI Train Horn Kit 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 2, 2026. Every spec below comes from Vevor’s official product page for this SKU, cross-checked against Vevor’s own customer-review page and the product pages for the three sibling 4-trumpet kits. All sources are listed at the end of the article.

Quick verdict

The 6-liter “150 PSI” kit is the middle child of Vevor’s 4-trumpet lineup, and the one we would point most first-time buyers toward if they insist on Vevor. For $125.99 you get four stainless-steel trumpets on a bolt-down bracket, a 1.6-gallon steel tank with gauge and pre-mounted 12V compressor, a solenoid valve, and extra hose and thread tape. It costs about $18 more than Vevor’s other 1.6-gallon kit, and in exchange you get stainless trumpets instead of zinc alloy, a stainless braided leader hose, and a slightly higher 95/125 PSI switch. The 150 dB headline has no test distance and the “150 PSI” is a compressor ceiling the tank never actually reaches in normal operation, so treat both as marketing. We rate it 3.5/5: honest hardware for the money, held back by loose acoustic claims, missing wiring and switch, and no stated warranty.

What it is

This is a complete, tank-fed 4-trumpet train horn kit sold direct by Vevor under SKU LBPJ6LFTJD4H00001V0. It is aimed at pickup, SUV and van owners who want a locomotive-style chord without paying HornBlasters or Kleinn money, and who are comfortable running their own wiring. The format is the classic budget layout: a horn cluster on a steel bracket, a separate tank-and-compressor assembly, and an air line between them. Vevor lists it for trucks, cars and motorcycles, but at 19.5 pounds shipped and with a tank over 16 inches long, it is realistically a truck or full-size SUV kit. See our Vevor brand hub for every Vevor horn we have covered.

Vevor sells several 4-trumpet configurations, and their names are confusingly similar. Here is how this kit sits against its three tank-fed siblings, using the live prices and specs on each Vevor product page at the time of review:

Vevor 4-trumpet kit	Tank	Switch (on/off)	Compressor	Weight	Price
0.8 gal / 3 L kit	0.8 gal	90 / 120 PSI	HS-550, 170 W	12.0 lb	$89.90
1.6 gal / 6 L, 120 PSI kit	1.6 gal	90 / 120 PSI	HS-660, 190 W	13.4 lb	$107.90
1.6 gal / 6 L, 150 PSI kit (this review)	1.6 gal	95 / 125 PSI	150 PSI max, model not disclosed	19.5 lb	$125.99
2.6 gal / 10 L, 160 PSI kit	2.6 gal	110 / 160 PSI	HS-1000A, 280 W	20.3 lb	$167.90

We have already reviewed the 1.6-gallon 120 PSI kit and the 2.6-gallon 160 PSI kit.

A note on the two pressure numbers, because Vevor’s marketing blurs them. The compressor is rated to 150 PSI, but the factory pressure switch turns it off at 125 PSI. In normal use the tank will sit between 95 and 125 PSI, exactly the same working band as most budget kits, and only about 5 PSI higher than Vevor’s cheaper 120 PSI sibling. A verified Vevor reviewer on this listing flagged the PSI spec as misleading for that reason. If you want the full 150 PSI you would need a different switch, and our pressure switch guide explains what that involves.

What’s in the box

Per Vevor’s contents list:

• Four stainless-steel trumpets pre-mounted on a carbon-steel bracket with a 12V solenoid valve
• 1.6-gallon steel air tank with pressure gauge and push-to-connect outlet fitting
• 12V compressor pre-mounted on the tank, with stainless braided leader hose and in-line fuse holder
• 6.56 ft (2 m) of extra 10 mm air line
• One roll of thread-sealing tape
• Mounting hardware

What is not in the box, in Vevor’s own words: wires and power switches. That means no relay, no horn button, no power cable from the battery to the compressor, and no fused feed for the solenoid. Budget another $20 to $40 and an hour of work for those parts; our relay wiring guide and activation options guide cover the choices.

Pros

• Stainless-steel trumpets, where the three sibling kits in the table above use zinc alloy with an anti-rust coating
• Complete air system for $125.99: tank, gauge, compressor, solenoid, braided leader hose and extra line in one box
• Automatic 95/125 PSI pressure switch and automatic-reset thermal overload on the compressor are disclosed on the product listing
• Oil-less compressor design, so no maintenance oil to check
• 4.6-star average from 22 verified vevor.com reviews, with zero 1- or 2-star ratings

Cons

• 150 dB claim has no test distance; budget quad kits generally meter well below their headline in third-party testing
• ”150 PSI” is a compressor ceiling; the tank actually cycles between 95 and 125 PSI out of the box
• Wiring, relay, horn button and power switch are not included
• No compressor model, wattage, duty cycle, amp draw or chord frequencies are published
• No warranty term is stated on the product page, only 30-day returns and paid third-party protection plans
• User reports on the listing mention a hose pulling off its crimp, no relief valve, and trumpets dented in shipping

Alternatives

• Vevor 4-Trumpet Kit, 1.6-gal 120 PSI — same tank volume for $107.90 with zinc-alloy trumpets and a lighter 190 W HS-660 compressor; the same kit is also listed at FactoryPure.
• Vevor 4-Trumpet Kit, 2.6-gal 160 PSI — the biggest-tank Vevor for $167.90; a 280 W compressor and 110/160 PSI switch give it more air per blast and a higher working pressure than the 6-liter kit.
• Vixen Horns VXH4124B — an all-metal 4-trumpet horn only, around $92, for builders who already run onboard air and want a fuller chord than Vevor’s short trumpets.
• HornBlasters Outlaw 127H — the step-up option: one real train horn at a distance-rated 142 dB with a 2-year warranty, at roughly four and a half times the price.

Install / compatibility notes

Electrical. The kit runs on any 12V negative-ground vehicle. The compressor and solenoid come with short pigtails only, so you supply a relay, an inline fuse near the battery, heavy-gauge wire for the compressor circuit, and a momentary button or toggle for the solenoid. Vevor does not publish amp draw, so size the compressor circuit conservatively; our amp draw and fuse guide walks through it.

Air. The compressor ships mounted on the tank with the braided leader already attached, so the only air connection you make is the 10 mm push-fit line from tank outlet to solenoid. Two meters of extra line is enough for a bed-mounted tank and bumper-mounted horns on a mid-size truck, but a long-bed install may need more. Wrap threaded fittings with the included tape and pressure-test before final mounting; our bench test guide covers the first fill.

Mounting. The trumpet cluster is 14 inches long and about 4.5 inches tall on its bracket, so it fits behind most truck grilles or under a bumper. The tank assembly needs roughly 16 by 6 by 11 inches plus clearance for the compressor’s air filter. Vevor calls the tank waterproof and shock proof, but the compressor has an exposed intake filter, so keep it out of direct spray. Reviewers on the listing describe keeping the tank-and-compressor unit in a tote or toolbox in the truck bed to keep weather off it; one wished for a protective box around the assembly.

Vehicles. Full-size and mid-size pickups and body-on-frame SUVs are the natural fit. Sedans and crossovers usually lack room for the tank-and-compressor unit, and the 19.5-pound total is a lot to hang under a unibody. Check our where to mount guide for placement.
