Nilight LED Trailer Light Kit: Square Stop, Turn and Tail Lights

Upgrade your trailer lighting with the Nilight LED Trailer Light Kit, engineered for 12V DC systems on trailers, boats, campers, RVs and more. The set blends tough, weather-ready hardware with bright, clear signaling to enhance visibility and safety on the road, water, or campsite. Designed to be a practical, all-in-one solution, it helps you project your signals with confidence while keeping the installation approachable for DIY setups.

Bright, dependable illumination

The kit uses high quality 2835 and 5050 SMD LEDs known for stable output and long life. The result is reliable brightness across running lights, turn signals, and brake indications, helping other drivers notice your presence from a distance and in varying lighting conditions. You’ll experience a crisp, even glow that complements the overall signaling system without overpowering adjacent lights.

• Durable LEDs designed for long-lasting performance
• Unified signaling across run, brake, and turn functions

Versatile, user-friendly installation

The square lights mount on the surface with a practical stud-mounted design, pairing with a license light on the left and right sides. The 16-inch brake tail light bar attaches with end screws, making the assembly straightforward for many trailer configurations. The included hardware is chosen to support secure mounting and a clean, professional look.

• Simple stud-mounted square lights
• End-screw mounting for the brake tail bar

Clear, color-coded wiring for reliable connections

Wiring is designed to be intuitive, with color codes guiding ground, running lights, and turn/brake signals. The bar and side markers get their own straightforward connections, helping you identify each function during setup and maintenance.

• White ground, brown running light
• Yellow/Green left/right turn and brake signals
• Bar: White ground, Black tail, Red brake
• Side markers: White ground, Black positive

Built to resist the elements

With a high level of sealing, the lights are designed to stay dry in challenging environments. Each square light is independently sealed and features a water drainage notch on its sides to channel away moisture that may enter the shell, helping maintain performance over time.

• Waterproof construction for outdoor use
• Individual drainage notches prevent moisture buildup

Wide compatibility and full functionality

This all-in-one kit covers running light, side marker, license plate illumination, turn signals, parking light, stop and brake, and tail light roles. It suits 12V DC vehicles up to 80 inches wide and fits a broad range of trailers, boats, trucks, RVs, campers and more.

• Multiple lighting roles in a single kit
• Broad compatibility with common 12V setups
