FITMENT GUIDANCE

The right lamp.
The right harness.

Compatibility depends on the lamp, truck, production year, cab and wiring. Check the complete combination before ordering.

Prepare a quick fitment request

CHECK VEHICLE FITMENT

Start with your truck.

Match the vehicle and its original lighting, then check the exact reference and any installation conditions. If a model or period is missing, ask us to confirm.

Source dates and installation notes

Vehicle-specific manufacturer results were checked on 7 October 2026; their publication dates are not stated. Two manufacturer pages are incomplete and are marked in results. The earlier lamp PDF is dated November 2023; its harness tables are dated September 2022.

Check dimensions and available installation space before purchase. Wiring modifications require a professional installer.

For supported lamps on vehicles with ESS, connect the dedicated harness supplied with the lamp. Hazard operation then uses standard flashing; consult the lamp instructions.

Reference versions are exact. Compatibility is not transferred to newer revisions or products absent from these tables.

Open-ended periods are reproduced as printed. Vehicles later than the source date are not covered by that document.

  1. PDF note 1: Standard flashing only; sequential operation is not supported.
  2. PDF note 2: SEA starting and ending actions must not be used on public roads.
  3. PDF note 3: For 12V vehicles, only cells explicitly marked note 3 are listed.
  4. PDF note 4: Vehicle-system changes are required, with additional installation labour.
  5. PDF note 5: This canceller is not required when the original vehicle lamps are LED.
  6. PDF note 6: Not applicable to vehicles equipped with the optional emergency stop signal (ESS).

Send the truck details first. We will help identify the lamp, load resistor and plug-in harness as one fitment system.

01 / READ THE SYSTEM

Three parts of one answer.

Lamp
The OIRAN product and exact part number.
Resistor
The vehicle-specific load solution, where required, for warning and flash-rate behavior.
Harness
The plug-in connector set selected for the truck, designed to avoid cutting factory wiring.
Remarks
Cab, connector, production-year or position exceptions that affect fitment.
02 / PUBLISHED HARNESS APPLICATIONS

15 documented harness codes.

The active-list applications below identify the published vehicle family and harness use. They do not replace a production-year and connector check.

Current availability and exact vehicle fitment must be confirmed with a distributor.

04 / REQUEST A CHECK

Not listed? Send five details.

Truck maker, model, production year, cab type and the OIRAN product you want to install. A clear photo of the original lamp connector can prevent an incorrect harness match.
