Vehicle alert horn

The Grote 72100-5 is a 12 V electric horn rated at 125 dB for domestic vehicles. It produces a high tone through a steel body with black enamel finish. A mounting bracket is included for direct installation. This unit suits drivers who need a loud, factory-style replacement.

Thermals and power

The horn draws power from a standard 12 V DC vehicle system when activated. It has no continuous cooling requirement because it operates only during brief presses. The steel housing dissipates the heat generated during normal use without a fan. Noise output is fixed at the rated 125 dB level.

Deciding specification

The 125 dB output at 12 V DC determines whether this horn meets the legal or practical loudness requirement for the intended vehicle. Buyers who need a lower decibel rating or a different voltage must choose another model. The fixed high tone cannot be adjusted. The bracket fits the supplied mounting points only.

Questions about this item

How do I mount the Grote 72100-5 horn using the included bracket on a 12 V vehicle?

Bolt the supplied bracket to a solid metal surface, connect the horn terminal to a fused 12 V circuit and ground the case through the bracket; the step often missed is securing a clean chassis ground so the 125 dB output is not weakened.

What maintenance or replacement will the 125 dB electric horn need over time?

Inspect the diaphragm and electrical contacts annually for corrosion or moisture; replace the unit if output drops below 125 dB or if the black enamel finish shows rust that could affect the steel housing integrity.

What is the first limit reached when the horn is sounded continuously?

Sustained operation causes the coil to heat rapidly; thermal protection or wiring capacity will cut output before the 12 V supply is exhausted, so limit blasts to short bursts to maintain the rated 125 dB level.
