Frequently Asked Questions

The Mini Outlaw 127H Train Horn Kit is a complete system that includes Mini Outlaw Black train horn, HornBlasters 127H air source unit (1.5-gallon tank with 2L compressor), pre-installed 1/4" electric air valve, 20ft of 1/4" air line, complete wiring kit with fuse holder and fuses, mounting hardware, air line cutter, earplugs, and detailed instructions. Everything you need for installation is in the box.

With the 1.5-gallon tank operating at 120 PSI, the Mini Outlaw 127H kit delivers 4–5 seconds of powerful continuous honking per tank fill. The system automatically refills from 90 to 120 PSI in just 35 seconds, so you're ready to honk again quickly. The fast recovery rate ensures you have plenty of air for multiple blasts on the street or worksite.

Yes, the Mini Outlaw 127H Train Horn Kit fits perfectly on RAM 3500 trucks like Troy's 2025 model. The air source unit measures 15.2" L × 5.9" W × 12.8" H and can be mounted under the vehicle or along the frame. The Mini Outlaw horn measures 16.5" L × 14.5" W × 11" H, making it ideal for space-constrained installations on heavy-duty trucks.

The Mini Outlaw 127H Train Horn Kit is designed with resilience in mind, featuring weather-sealed construction for both the horn and air system. This ensures longevity in various conditions, making it perfect for heavy-duty trucks like the RAM 3500 that see both street and worksite use. The sealed design protects components from moisture, dirt, and debris, ensuring reliable performance over time.

The system requires 12-Volt DC power with a maximum amperage draw of 18 amps from the 2L compressor. The kit includes a complete wiring kit with fuse holder, fuses, and all electrical terminals, so you have everything needed for proper electrical installation. Make sure your RAM 3500's alternator can handle the compressor load during operation cycles, especially when running additional accessories or worksite equipment.
