Care information

To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:

  • Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
  • Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
  • For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
  • Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
  • Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
  • After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
  • If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

Product Description:

Refresh your trailer lighting with this RGP-assembled kit featuring TecNiq 4″ round LED tail lights, Jammy amber and red marker lights, a chrome license plate lamp, adhesive reflectors and a 25-foot 4-way flat wiring harness.

The two TecNiq T40 lamps provide stop, turn and tail functions through red LED lenses. Each lamp includes attached wiring leads, and two matching rubber grommets are supplied for installation in compatible round mounting openings.

Four compact marker lights provide amber and red side lighting. A separate TecNiq license plate lamp illuminates the plate, while two amber and four red adhesive reflectors provide passive visibility without electrical connections.

This bundle brings the main lighting components together for trailer repair, replacement or rewiring projects. Installation requires suitable mounting locations, wiring connections and proper grounding.
