Buying Guide – How to Choose the Best LED Trailer Light Kit
Selecting the right lighting kit involves evaluating several key factors that impact safety and longevity. These points will help you narrow down choices based on your specific trailer type and usage needs.
Waterproof and Submersible Ratings
Look for an IP67 or IP68 rating if you plan to tow a boat or drive through heavy rain. These ratings indicate that the unit is sealed against dust and water immersion. Without proper sealing, moisture can cause electrical shorts and failure.
Always check for specific sealing technologies like sonic welding or epoxy encapsulation to ensure durability in wet conditions.
Wiring Harness Quality and Length
A quality harness resists corrosion and abrasion over time. Look for UV-coated or braided nylon sleeves that protect wires from road debris. Length is also crucial; ensure the harness reaches your trailer rear comfortably without tension.
Prioritize kits with pre-soldered ends or color-coded wires to simplify the installation process significantly.
Light Output and Visibility
LEDs should offer high brightness with minimal warm-up time. Check the lumen output and number of diodes for sufficient illumination. Clear visibility in fog or low light is essential for safety and road compliance.
Ensure the lights cover all required functions such as stop, turn, and tail lights effectively.
Compatibility and Size
Most kits are designed for trailers under 80 inches wide. Verify dimensions to ensure they fit your existing mounting points. Universal designs allow for easier installation across different vehicle types.
Choose a system that matches the width and shape of your trailer for a secure fit.
Compliance and Certifications
DOT FMVSS 108 certification ensures the lights meet federal safety standards. Using non-compliant lights can result in fines or failed safety inspections. Always verify regulatory compliance before purchasing a kit.
Certified products guarantee that the lighting meets legal requirements for public roads.
Durability of Housing
Housings made from ABS or high-impact plastic resist cracking under stress. Materials should withstand UV exposure and temperature changes without fading. Check if the lens is made of durable acrylic to prevent scratching.
Robust construction ensures your lights stay intact after exposure to road debris and weather.
Additional Features
Some kits include extra components like license plate brackets or brake light bars. These features can save money by eliminating the need for separate purchases. Check for inclusion of all necessary hardware and mounting screws.
A complete set ensures you have everything needed for a professional installation in one box.
Warranty and Support
Reputable brands offer warranties to cover defects in materials or workmanship. Good support teams can help resolve installation issues quickly. Review terms to know what is covered and for how long.
A solid warranty reflects confidence in the product quality and provides peace of mind.
How to Use and Care for Your LED Trailer Light Kit
Start by matching the wiring colors to your vehicle harness before connecting. Always disconnect the power source to prevent shorts during installation. Use a multimeter to test continuity if unsure about connections.
After mounting, apply a thin layer of dielectric grease on connectors to prevent corrosion. Keep the drainage holes clear to allow moisture to escape. Inspect seals annually for cracks or damage.
Periodically clean the lens surface with a damp cloth to maintain brightness. Replace any damaged mounting hardware immediately to keep lights secure. Check your electrical connections after long trips to ensure safety.
Frequently Asked Questions
Are LED trailer lights better than incandescent bulbs?
Yes, LEDs provide brighter light with faster response times and consume less power. They also last longer and are more resistant to vibration compared to traditional bulbs. This makes them a safer and more efficient choice for trailers.
What does IP67 mean for trailer lights?
IP67 indicates the lights are dust-tight and can be submerged in water up to one meter for thirty minutes. This rating ensures reliable performance even when driving through deep puddles or launching boats. It is a key feature for marine towing.
Do I need to buy a separate wiring harness?
Most comprehensive kits include the necessary harness and plug. However, budget models might require you to purchase one separately. Always check the package contents before buying to avoid extra costs and trips.
How do I ensure my lights are DOT compliant?
Look for explicit mentions of DOT FMVSS 108 standards in the product description. Certified lights meet federal requirements for color, position, and visibility. This ensures you stay legal and avoid fines on public roads.
Can I install LED lights on a non-electric trailer?
All standard trailers need a 12-volt power source to run LED lights. You will need to install a wiring system or upgrade your vehicle hitch. Ensure your tow vehicle can supply the required current safely.
What should I do if my lights flicker?
Check for loose connections or ground issues causing inconsistent power. Ensure the harness is secure and free of corrosion. If problems persist, inspect the LED unit for internal damage.
How long do LED trailer lights typically last?
High-quality LED units can last tens of thousands of hours of operation. Their lifespan far exceeds incandescent bulbs when installed correctly. Proper waterproofing helps ensure they reach their full potential duration.
Are all trailer lights universal fit?
Most are designed for trailers under 80 inches wide. Always check the dimensions and mounting options to ensure compatibility. Some specialty trailers may need custom brackets or specific models.
Final Thoughts on Choosing the Best LED Trailer Light Kit
Choosing the right kit depends on your specific towing needs and environmental exposure. The MAXXHAUL and Partsam options offer reliable performance for standard utility and boat trailers. Each product provides distinct advantages regarding wiring quality and waterproofing.
Prioritize waterproof ratings and harness durability to avoid frequent replacements. Investing in quality materials ensures long-term safety and compliance. Selecting a complete kit saves time and effort during the installation process.
