MCC/Smart Roadster/Coupe Horn replacement
How much does a MCC/Smart Roadster/Coupe horn replacement cost?
The MCC/Smart Roadster/Coupe’s horn is a warning device which, by law, is only allowed to be used to warn other road users or animals of the MCC/Smart Roadster/Coupe’s approach and possible imminent danger. It can be used in conjunction with an anti-theft device or alcohol ignition interlock. A road vehicle must be equipped with a functioning horn and it should not be used for anything other than its purpose, otherwise you could be fined.
The horn activation point, or switch, is on the MCC/Smart Roadster/Coupe’s steering wheel. Since it is a warning device to be used in an emergency situation only it is within easy reach and its very quick to activate. It only takes a second to strike the steering wheel. The actual warning sound comes from the front of the MCC/Smart Roadster/Coupe, which is where the horn is found.
When the horn switch is pressed in the cabin it activates a relay which allows power to flow to the horn. On modern MCC/Smart Roadster/Coupe’s it generates a beep sound as the warning. There will be at least one horn per vehicle although some MCC/Smart Roadster/Coupe’s have two horns that emit different frequencies, or notes, as this is more obvious in a noisy environment. The exterior of a horn can be small enough to fit in the palm of the hand and is usually made of plastic and/or metal. A horn will produce around 109-112 decibels of sound.
A plunger’s rapid back and forth movement flexes and vibrates the diaphragm, creating the sound you hear when pressing the MCC/Smart Roadster/Coupe’s horn switch on the steering wheel.
A working warning device on a MCC/Smart Roadster/Coupe is a requirement. You never know when it may be needed - you might need to shoo some cows off the road on your next country drive. If your horn is sounding hoarse then best get it replaced as soon as possible.
