Holden Astra Horn replacement
How much does a Holden Astra horn replacement cost?
The Holden Astra’s horn is a warning device which, by law, is only allowed to be used to warn other road users or animals of the Holden Astra’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 Holden Astra’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 Holden Astra, 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 Holden Astra’s it generates a beep sound as the warning. There will be at least one horn per vehicle although some Holden Astra’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 Holden Astra’s horn switch on the steering wheel.
A working warning device on a Holden Astra 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.
