The factory-installed horn is a poor match for a vehicle enthusiast’s souped-up ride. When someone puts all the time and money into customizing a vehicle to their particular needs, hearing the wimpy sound of the standard horn, is a complete oxymoron. It’s made worse, because the enthusiast can do something about it by purchasing and installing one of many varieties of train horn kits sold as aftermarket automotive products.
The kits feature everything from flashy chrome trumpets, to all of the components needed to bring an authentic-sounding locomotive whistle to your vehicle. However, in keeping with noise ordinances, they are scaled down in both size and sound output from those used on actual locomotive engines. The great thing about purchasing this aftermarket product as a kit is that everything needed to install and operate the horn is included, thus eliminating multiple trips to the store for the right part.
Instructions for installing train horn kits are usually very thorough so that anyone who knows their way around a vehicle should be able to install the kit. It should be noted, however, that even though the instructions are quite complete, it is not a fast install and several hours should be set aside to complete the project.
The quality of an aftermarket kit is most often judged on the sound of the completed horn. The trumpets can vary slightly in size and shape from one manufacturer to another, which impacts the sound output. Generally train horn kits offer anywhere from two to four trumpets, each of which sounds a different note. For this reason, the train horn kits offering the most trumpet variations are usually the most popular.
One final note is to do your research and ask questions before making a purchase decision.
If you don’t know someone who already has a kit installed, check the Internet for forums and discussion boards that talk about the various models available and the pros and cons of each.
