Applications & use cases
Horn dead or weak
A forklift horn that clicks, buzzes or stays silent with a good supply at the terminals has a burned contact or a seized diaphragm. Check the fuse and the horn button first, then put a meter on the horn terminals while the button is pressed. Battery voltage there with no sound means the horn itself has failed.
Site safety checks
Most sites require a working horn on every truck at the start of shift. A spare horn on the shelf keeps a truck working instead of tagged out while a part is ordered.
Water and wash down damage
Horns mounted low on the chassis or behind the counterweight take spray from wash down and wet yards. A corroded horn is cheaper to replace than to strip and clean.
Fleet spares
One horn per voltage covers most trucks in a mixed fleet, so a workshop can stock a few horns instead of a different part number for every make.

Frequently asked questions
Is this a genuine forklift maker's part?
No. It is an aftermarket 12 V disc horn sold by Spare Part Mart. It is not made by or affiliated with Yale, Hyster, Toyota, Clark or any other forklift maker; their part numbers are listed only to show which horns it replaces.
How do I know it fits my truck?
Match the voltage first: this horn is for 12 V horn circuits. Then check the part number on your old horn or in your parts manual against the table on this page, and check there is room for a disc horn with a single bolt bracket where the old horn sits.
Will it plug straight in?
It has two flat spade terminals. If your truck's horn lead ends in matching spade connectors it connects straight on. If the old horn had a moulded plug, fit two insulated spade connectors to the lead.
Why is the 12 V horn sold in pairs?
A single 12 V horn costs less than our minimum order line, so it is sold as a pack of 2: one to fit and one for the shelf.
Does polarity matter?
A simple electric disc horn like this one works either way round on the two terminals. Disconnect the battery before working on the wiring and check the horn sounds before the truck goes back to work.
