Product Specifications

Backup / Reverse Lighting Function

This fixture is intended for vehicle backup-lighting applications.

Backup lights illuminate the area behind a vehicle during reversing and help communicate reverse operation to other road users.

For regulated on-road applications, backup lamps must satisfy applicable illumination-color, visibility, and photometric requirements.

Although backup lights normally produce white illumination, the supplied description does not explicitly confirm this fixture's emitted light color.

Verify the light color and applicable regulatory markings before marketing it as a compliant on-road backup lamp.

LED Lighting Technology

This model uses LED technology rather than an incandescent bulb.

LEDs produce light using solid-state electronic components instead of heated filaments.

LED lighting is commonly selected for modern vehicle lighting systems and replacement applications.

However, the supplied product information does not identify LED count, lumen output, wattage, rated operating life, or electrical efficiency.

These specifications should be confirmed before making claims about brightness, energy savings, or service life.

4-Inch Round Configuration

The nominal 4-inch round format is commonly encountered in commercial vehicle lighting assemblies.

This design can be considered for compatible rear lighting locations on trucks, trailers, RVs, and specialty vehicles.

However, a nominal 4-inch designation does not guarantee compatibility with every round mounting opening.

Actual outside diameter, fixture depth, mounting method, and required clearance should be verified before ordering.

Standard Plug Connection

The standard plug interface is a defining feature of this model.

A compatible plug connection allows the lamp to be integrated into an appropriate vehicle lighting circuit.

For OEM manufacturers and fleet maintenance teams, identifying the connector configuration can help simplify component selection and replacement planning.

The supplied description does not identify the exact connector standard, number of terminals, polarity, or whether a matching plug or wiring pigtail is included.

A standard plug designation should not be interpreted as universal compatibility with every vehicle harness.

Potential Applications

Commercial Truck Backup Lighting

A potential OEM or replacement option for compatible commercial truck reverse-lighting assemblies.

Cargo and Utility Trailers

May be suitable for qualifying trailers equipped with compatible backup-light mounting locations.

RV and Motorhome Lighting

Can be evaluated for recreational vehicle reverse-lighting applications where electrical and mounting requirements match.

Box Trucks and Work Vehicles

An option for compatible rear lighting assemblies on work trucks and specialty vehicles.

Fleet Maintenance

May be considered when replacing an existing round LED backup lamp with matching dimensions and electrical connections.

OEM Vehicle Manufacturing

The 4-inch round configuration, LED technology, and standard plug interface provide useful specifications for manufacturers selecting reverse-lighting components.

These are potential applications rather than confirmed vehicle fitment or regulatory approvals.

Installation Considerations

Before installation, confirm:

• Actual lamp outside diameter and depth.

• Mounting configuration and required opening dimensions.

• Whether a separate mounting grommet, flange, or bracket is required.

• Operating voltage and electrical requirements.

• Standard plug type and terminal configuration.

• Whether a matching plug or pigtail is included.

• Correct polarity and reverse-light circuit connection.

• Emitted light color.

• Applicable DOT, FMVSS, and SAE requirements.

• Weather-exposure suitability.

• Compatibility with the intended vehicle and installation location.

Follow Kaper II's installation instructions and applicable vehicle lighting requirements.

Important: The supplied description confirms a 4-inch round LED backup light with a standard plug connection. Mounting configuration, illumination color, diode count, operating voltage, connector details, included accessories, and regulatory certification require verification.
