Your car or truck horn is your “voice” to the outside world. No one really misses their car horn until they need it! A car horn is a simple device based on an electromagnet and an internal diaphragm to move air and generate sound. Most state’s vehicle safety inspections require your vehicle to have an operating horn to pass inspection.

There are many reasons you may need to fix or repair a broken car horn. There may be a problem with the switch, or button. There could be a break in the wiring from the switch or button to the horn relay, or from the relay to the horn itself. The horn relay or horn itself may also be the problem, due to a broken electrical connection in the horn, or damage to the diaphragm.

For most applications we offer high and low tone horns. Typically cars that have only one horn will use the high tone horn. Cars or Trucks that have 2 horns will use 1 high, and 1 low tone horn. We also offer High Output horns. Some vehicles came from the factory with high output horns, and they are also used for some commercial applications and trucks.
