Buying Guide – How to Choose the Best LED Trailer Light Kit
Selecting the right LED trailer light kit involves evaluating several critical factors. Understanding these details will help you choose a kit that fits your trailer and ensures safety on the road.
Waterproof Rating
Waterproof ratings determine how well the lights can resist moisture and water intrusion. Look for IP67 or IP68 ratings if you plan to launch boats frequently. Higher ratings ensure the internal circuit boards remain safe from water damage.
Always verify the waterproof rating before purchasing if you use your trailer near water.
Wiring Harness Length
The length of the wiring harness is crucial for ensuring you have enough wire to connect the lights properly. Most kits offer 22 feet, but some include 25 feet for longer trailers. A longer harness prevents the need for extensions that can introduce weak points.
Measure your trailer from the hitch to the rear to determine the required wire length.
DOT Compliance
Federal regulations require trailers to meet specific lighting standards for road safety. Ensure the kit is DOT FMVSS 108 compliant to avoid fines. This compliance guarantees that the lights have sufficient brightness and correct positioning.
Check for compliance certifications on the product packaging or description before buying.
Light Functionality
Different trailers require different light configurations. Some kits offer 7 functions including stop, turn, tail, and side markers. Ensure the kit covers all necessary signals for your specific vehicle type.
Select a kit that matches your trailer's existing electrical requirements.
Material Durability
The construction material of the housing affects longevity in harsh weather. ABS plastic and reinforced lenses are common. Look for UV-resistant materials to prevent cracking under sun exposure.
Choose durable materials if your trailer is used frequently outdoors.
Installation Ease
A user-friendly wiring harness makes installation much faster and simpler. Color-coded wires and split Y-style designs reduce errors. Kits with pre-soldered ends also save time and improve connection security.
Prioritize kits with clear wiring diagrams for hassle-free setup.
Brightness and Output
LED brightness is measured in lumens or compared to halogen equivalents. Kits offering 5X brightness provide better visibility in fog or rain. High-output diodes ensure other drivers can see your trailer clearly.
Opt for higher brightness to improve safety in low-light conditions.
Included Mounting Hardware
Some kits include stainless steel screws and brackets while others do not. Full kits save you a trip to the hardware store. Check what is included in the box before purchasing.
Ensure all necessary mounting parts are included for a complete installation.
How to Use and Care for Your LED Trailer Light Kit
Start by cleaning the mounting surface on your trailer to ensure a secure fit. Remove any old tape or corrosion to allow the new bracket to sit flat. This step prevents wobbling that can lead to premature wear.
Connect the wiring harness carefully using the color-coded guide. Test all functions—stop, tail, and turn signals—before driving. Ensure no wires are exposed to moisture if not fully sealed.
Regularly inspect the lenses and brackets for signs of damage. Keep the drainage holes clear of debris to prevent water buildup. A quick rinse with fresh water after salt exposure helps maintain performance.
Frequently Asked Questions
Are these LED kits compatible with older tow vehicles?
Most LED kits are designed for standard 12V DC systems found in modern and older tow vehicles. However, you may need a load resistor if your vehicle's electrical system expects incandescent bulbs to prevent hyper-flashing. Always check your vehicle manual.
Do I need to install a new wiring harness?
If your current harness is damaged or too short, a new one is necessary. Many kits include a full harness, which simplifies replacement. Installing a new harness ensures a clean connection without existing wear.
Can I use these lights for boat trailers?
Yes, submersible kits with IP67 or IP68 ratings are perfect for boat trailers. They are designed to withstand water immersion during launches. Always check the waterproof rating before selecting a kit for marine use.
How long do LED trailer lights typically last?
LED lights have a lifespan of 50,000 hours or more. They are more durable than incandescent bulbs which burn out frequently. This longevity makes them cost-effective over the long term.
What wire gauge should I use for trailer lights?
A wire gauge between 18 and 14 is standard for trailer lighting. Thicker wire reduces voltage drop over long distances. Using the included gauge ensures reliable performance.
How do I mount the lights securely?
Use the provided stainless steel screws to secure the brackets. If mounting on wood, pre-drill holes to prevent cracking. Ensure the light is tight enough to withstand vibration.
Do these kits come with licenses plates?
Some kits include a license plate bracket, but the plate itself is usually not included. You will need to install your own plate on the bracket. Check the box contents for details.
Final Thoughts on Choosing the Best LED Trailer Light Kit
We reviewed ten top kits ranging from budget-friendly options to premium marine-grade solutions. Each offers unique strengths in wiring protection, brightness, and waterproofing capabilities.
Prioritize waterproof ratings and harness length based on your specific towing needs. Safety and compliance with regulations should be your main focus when making a decision.
Always check current availability and prices as these can fluctuate over time. Verify compatibility with your trailer dimensions before placing your order to ensure a perfect fit.
