Delivery time depends on the product, your destination, and availability — the estimated time for any item appears on the product page, and "Check where we deliver" confirms coverage for your postcode before you order. Next-day delivery is available on most products; the option appears at checkout when applicable. We deliver across the UK, Europe, the Middle East, and Africa. Use the country selector at checkout to confirm coverage and delivery options for your destination.

Voltage first — 12V or 24V to the machine, never crossed — then mounting and connector to the old unit, and tone: high, low, or the high-low pair that gives the two-tone voice most vehicles left the factory with. Current draw matters only where the circuit is marginal; everything is listed per horn.

Usually not first: horns live in the weather, but their circuits die faster — the switch contact in the wheel, the relay, the connector green with corrosion, and the bracket earth that completes the circuit. Twelve volts at the terminal with a good earth and silence convicts the horn; anything less convicts the supply.

The two-tone convention: paired high and low tones produce the fuller voice vehicles were designed around, and a single survivor of an original pair sounds thin because it is half a chord. Twin packs restore the pair; wiring is parallel off the existing feed, with the relay carrying the doubled draw it was sized for.

Yes — it must work, be audible and be appropriate in character, which makes the dead horn one of the cheapest fails going. The pre-test press costs nothing; the row's January demand suggests how often it's skipped.

Returns are accepted within 30 days of purchase, in original packaging, on orders delivered within the United Kingdom. For damaged-on-arrival items, report within 24 hours with photographs to [email protected] — we will typically arrange collection and replacement at no cost to you. For parts that don't fit your machine, the Fit Guarantee covers a hassle-free return at no cost. For buyer's remorse — you've changed your mind or ordered the wrong item, email us first to obtain a Return Merchandise Number; a restocking fee may apply. Refunds are issued to the original payment method once the return is inspected.

Horn

Horns are the machine's legal voice: the warning devices that vehicles must carry working and machinery sites expect, bought by voltage, tone and mounting, and replaced because weather kills them more than use does. PartsForMachines supplies horns within the electrical family, across the 12V and 24V systems the catalogue's machines run. The patterns follow the duty: disc horns, the compact standard of cars, vans and machinery, in high and low tones that pair for the two-tone voice, snail horns where the trumpet's resonance wants more presence, the heavy-duty and air-assisted patterns of trucks, and the reversing and warning sounders that overlap the safety ranges, all specified by voltage, current draw, tone and mounting per product. Matching is straightforward: voltage first, the old horn's mounting and connector, and tone to taste or to the pair being completed, with twin packs serving the two-tone convention. The diagnosis is short and damp: horns live in the weather at the front of everything, so failure is corrosion's, terminals and earths first, since a dead horn with good supply at its terminal is genuinely dead, but most dead horns never received the supply, the push's switch contact and the relay upstream sharing the blame, and the bracket's earth completing more circuits than buyers expect. A horn is also an MOT item: it must work and be audible, the annual reason this row sells in January. Relays and the electrical family sit alongside.
