Collection: Alarms & Horns

Use this Alarms & Horns collection to compare service parts represented in current listings for trucks, vehicles and loaders. The parts sense operating conditions, switch circuits or carry commands and signals between machine systems. Selection depends on signal range, voltage, connector keying, pin count, software generation and mounting location; a shared product name does not by itself confirm interchangeability.

Listing evidence links this group to cab and body, engine and fuel-system maintenance, making the machine plate and removed part useful references. Record the machine serial range during inspection.

• Verify the source number, complete equipment identity and fitted location.
• Measure or identify connector and pin count, thread or mounting style and operating range.
• Review voltage or signal range, equipment revision and all supplied connections.

Treat the product page as the source for Alarms & Horns contents and applications; use the specified service process for fitting and checks.

Fitment FAQ: Can similar items be interchangeable? Not automatically; differences in voltage or signal range or connector and pin count can change fitment.

Settle any fitment difference before ordering. The published 90-day return policy governs eligible returns.
