Supplier product reference · reviewed 18 October 2026
A four-emitter source reference kept separate from HM4 and H8 through its stated geometry and complete model name.
Published identification
Supplier-published entries. Ratings and configuration still require current documentation.
NV-HS4 is not merged with the HM4 or H8 entries simply because all are compact round warning modules. Its official table identifies a 55 × 21.6mm envelope, twelve patterns and a 20cm lead. These identifiers belong together in a request; similar voltage or lens appearance does not establish interchangeability.
The prepared illustration retains the source’s raised clear optic and black flanged body. Single- and dual-colour options appear in the source, but the shared four-emitter table does not fully explain every colour revision. The body also suggests internal mounting in other lamps. That suggestion is not permission to alter a host assembly or evidence that its optics and approval remain unaffected.
Procurement checklist
Keep the item identity, physical version and supply scope together. Use the questions alongside the published specifications when preparing a sourcing brief.
Ask for the complete reference, selected single- or dual-colour version and matching emitter/control documentation. The four 3W entry is a catalogue description, not independently measured demand. Keep the code visible when comparing similar round modules in this supplier’s range.
Request a drawing with flange, fixing pitch, lens protrusion and cable clearance. The diameter/height table does not define a universal opening in another lamp. No host-lamp modification procedure or blanket compatibility assertion is provided by this reference page.
Confirm pattern selection, synchronisation interface, any memory function documentation, lead termination and mounting hardware. The source’s twelve patterns and broad application statements do not prove compatibility with existing switches or an approved emergency-warning configuration. Ask for documents tied to the offered revision.
A catalogue input range does not establish compatibility with an electric forklift’s traction battery or accessory circuit. Ask the equipment supplier to identify the documented accessory supply, control interface and intended application. The truck model, serial number and installed-component record remain important even when a lamp or controller looks similar.
Official NV-HS4 body and table support a separate catalogue identity. Visibility, synchronisation, protection and application claims remain supplier statements. No universal emergency-vehicle fit, installed warning coverage or independently verified safety effect is established.
This reference is neither a quotation nor a stock, delivery or authorisation commitment. Request a current written proposal from the quoting entity. Preserve the item reference, quantity, destination and included accessories in that proposal so that changes of configuration remain visible.
