Nilight 4 inch Round Trailer Light (Pair)

The Nilight 4-Inch Round Trailer Light (Pair) offers exceptional brightness and reliability, equipped with 24 high-performance SMD LEDs that ensure superior lighting and heat dissipation. Combined with a high-transparency lens, it delivers outstanding illumination, significantly enhancing driving safety. Designed with dual brightness modes, the light functions as a low-brightness tail light and a high-brightness turn signal light, allowing vehicles behind to easily detect changes in brightness.

Installation is straightforward: prepare a 4.57-inch diameter hole with a depth of 1.89 inches, insert the grommet and light in sequence, and connect the 3-prong plug with the provided wiring. The light features a sealed IP67 waterproof design, achieved through ultrasonic bonding of the lens and housing, effectively preventing water ingress—even in severe weather conditions.

Perfectly suited for 12V DC vehicles, including trucks, trailers, tractors, semi-trailers, horse trailers, travel trailers, dump trucks, boats, and other special vehicles, this light ensures optimal performance as a tail light or turn signal light. The protrusion on the outer ring of the light aligns securely with the groove in the grommet, preventing displacement, while the tightly fitting back plug resists loosening.

With its completely sealed and waterproof build, the Nilight 4-Inch Round Trailer Light is designed to isolate moisture, ensuring long-lasting performance and reliability. Backed by a 2-year warranty from Nilight, this light offers an easy installation process with included screws, nuts, and a standard 3-prong plug, making it a dependable choice for enhanced safety and visibility on the road.

Lost or Missing Packages in Transit

Auto Hauler Gear works with trusted carriers including USPS, UPS, FedEx, and DHL. While the vast majority of shipments arrive without issue, delays can occasionally occur once a package is in the carrier’s possession.

A shipment may be considered lost in transit if:

• It has been 7 days past the original estimated delivery date, or
  
• Tracking shows no movement or updates for more than 7 consecutive days.
  

If either condition applies, please contact us promptly so we can begin the resolution process.

Our Resolution Process

Once verified, Auto Hauler Gear will:

• Initiate a trace and/or file a claim with the carrier.
  
• Expedite a replacement shipment when appropriate.
  

In many cases, once a claim or trace is filed, the carrier locates the package and it resumes transit to the destination.

Duplicate Delivery

If a replacement shipment is sent and the original package is later delivered, we kindly ask that you notify us. We will provide a prepaid return shipping label for the duplicate merchandise.

Claim Time Limits

Carrier claim windows are limited. Claims must generally be initiated within 60 days of shipment, though certain circumstances may allow filing up to 9 months from the original shipment date, depending on carrier policies and shipment type.

For this reason, Auto Hauler Gear actively monitors package tracking to help ensure delays are minimal and addressed promptly. However, customers are also responsible for monitoring their delivery status and must report delayed or missing shipments as soon as possible to preserve eligibility for carrier claim recovery and replacement consideration.

Auto Hauler Gear reserves the right to determine when a shipment qualifies as lost in transit based on carrier tracking data, service guarantees, and carrier policies.
