Year 2025

Vehicle 2025 RAM ProMaster 2500

2025 RAM ProMaster 2500 Cargo Van owner John M. upgraded his van with our HornBlasters Sniper Electric Horn for a louder, more aggressive horn sound that fits perfectly with the work van setup. The Sniper Electric Horn was installed in the front engine bay area, giving this ProMaster a clean install while delivering a major upgrade over the factory horn—no train horn tank, no frame-rail plumbing, just a compact 12-volt package built for vans and light commercial rigs.

The HornBlasters Sniper Electric Horn (EH-AH) is a self-contained electric air horn: stealth black trumpet, on-demand mini compressor, 40-amp relay and wiring harness, air tubing, and mounting hardware per the product listing. HornBlasters rates it at 12-volt DC with up to 20 amps draw during honk—more than most factory horns—so plan proper relay and fuse protection (and consider the optional Electric Horn Wiring Kit if your van needs heavier-gauge wire than stock circuits provide).

The Sniper Electric Horn is a perfect option for RAM ProMaster owners looking for a compact but powerful electric horn upgrade without needing a full onboard air system. Whether it is for daily driving, work use, or improved attention on the road, this setup delivers a huge improvement in sound and presence. Big thanks to John M. for choosing HornBlasters for his 2025 RAM ProMaster 2500 Cargo Van build.

Frequently Asked Questions

No. The Sniper Electric Horn is a self-contained electric package: HornBlasters supplies the Sniper trumpet, on-demand mini compressor, 40-amp relay, wiring harness, tubing, and mounting hardware (EH-AH). You still need clean 12V power and chassis ground, but you are not plumbing a multi-gallon tank like a Conductor’s Special or Outlaw train horn kit. John M.’s ProMaster build is exactly that kind of compact upgrade.

Yes—John’s install uses the front engine bay for a clean work-van presentation. ProMaster engine bays vary by roof height, HVAC routing, and upfitter equipment, so map clearance to moving parts, heat, and service access before you drill. Secure the Sniper Electric Horn and mini compressor so nothing rattles on rough roads, route tubing away from hot components, and follow the included HornBlasters instructions.

The Sniper Electric Horn can pull up to 20 amps—more than most factory horn circuits. HornBlasters includes a 40-amp relay and warns that wiring the horn without proper relay and fuse protection can stress your electrical system if it was not designed for that load. Add the Electric Horn Wiring Kit at checkout when you need thicker-gauge wire and a complete harness beyond what your ProMaster already has.

The Sniper is built for owners who want a major sound upgrade without the footprint of compressors, tanks, and DOT air line. Train horn kits deliver locomotive-scale chords and longer honk windows but need more underbody or spare-well real estate—tough on some upfitted ProMasters. John’s van proves the Sniper sweet spot: loud, aggressive, and practical for daily commercial use. When you need true train horn output, browse complete kits instead.

Start with the Sniper Electric Horn product page for specs, manuals, warranty language, and add-ons. Explore complete kits when you are ready for onboard air, or visit HornBlasters’ train horns & air horns collection to compare other standalone horn options.
