Partsam 2-Pack 15-Inch Red LED Trailer Light Bar – 11 LEDs, Sealed, DOT Compliant

Two-Pack 15-Inch Red LED Trailer Light Bars for Clear Signaling

Upgrade trailer visibility with the Partsam 2x red 15 inch LED light bars. Built to be sealed and waterproof, these units combine a rugged plastic housing with a durable polycarbonate lens to stay bright in challenging weather. The result is a clean, noticeable signal that helps other drivers see your stopping and turning cues from a distance, without consuming extra space on your trailer surface.

Each light bar packs 11 diodes for a crisp, bright glow that stands out in daylight and at night. The lens is sonic welded to the housing, creating a sturdy, weather resistant assembly that keeps moisture and dust out while remaining easy to wipe clean after road spray or rain. This combination aims to deliver reliable signaling in everyday use on trailers and work vehicles.

Dimensions and fit are designed with flexibility in mind. The bars measure about 15.5 inches long, 1.3 inches wide, and 0.47 inches thick, with a center hole distance of 14.5 inches. A small wire exit nub is provided; you may need to cut a matching opening to pass the wires through for a neat installation. Expect an exit opening around 9/16 inch to accommodate typical wiring harnesses.

Wiring is simple and standardized. The white wire serves as ground, the red wire provides high brightness for stop, turn, or brake functions, and the black wire acts as the tail light. The unit includes two screw holes for mounting, and you can install it horizontal, vertical, or at an angle to suit your trailer shape and mounting space.

Applications span a wide range, from semi trailers and cargo trailers to boat trailers and work vehicles. The lighting design also makes these bars compatible with overland setups and robust trucks that require clear, dependable signaling signals from a compact, low-profile bar. The product is DOT compliant, reflecting industry standard expectations for visibility and signaling performance in road use.

Practical benefits and usage notes include weather resistance from the sealed design, bright LED signaling from eleven diodes per bar, and the flexibility to install in multiple orientations. While actual results can vary with installation and vehicle configuration, these parts are intended to offer a practical balance of brightness, durability, and ease of use for everyday trailer signaling needs.

Installation and maintenance considerations

• Sealed, waterproof construction helps protect against rain, mud, and road spray.
• Durable polycarbonate lens resists impact and fading in sun exposure.
• Quick mounting with two screw holes; orientation can be horizontal, vertical, or angled.
• Simple wiring scheme uses white for ground, red for high brightness signal, and black for tail light.
• Dimensions and hole spacing fit a variety of trailer applications; plan for a clean interface with your mounting surface.

If you are planning a trailer lighting upgrade, these Partsam bars offer a practical option that emphasizes visibility and reliability without promising specific results. Consider them as part of a broader approach to trailer signaling that prioritizes safety and consistency in all weather conditions.
