Buyer’s Guide: What to Consider
Choosing the right trailer light kit involves several key factors. This guide helps you understand the differences in lighting technology, waterproofing, and included components, so you can pick a kit that meets your specific needs and budget.
- LED vs Incandescent: LED lights are brighter, last longer, and use less power, but cost more upfront. Incandescent bulbs are cheaper but dimmer and require more frequent replacement. For most users, LED is the better long-term investment.
- Waterproof Rating: If you use a boat trailer, look for IP67 or IP68 ratings, which indicate the lights can be submerged. Even for non-boat trailers, a good waterproof rating protects against rain and moisture, extending the life of your lights.
- Wiring Harness Length: Standard harnesses are 22 feet, but longer trailers may need 25 feet or more. Measure your trailer from the connector to the rear lights to ensure you have enough reach. A split Y-style harness simplifies routing to both sides.
- Compliance and Certification: DOT compliance (FMVSS 108) ensures the lights meet federal safety standards, making them road-legal. Always check for this certification, especially if you plan to use the trailer on public roads.
- Included Components: Some kits include only tail lights, while others add clearance lights, license plate brackets, and even third brake lights. Consider what you need for your trailer type and choose a kit that provides everything in one package.
Conclusion
Selecting the best trailer light kit depends on your trailer type, usage, and budget. For boat trailers, submersible options like the CZC AUTO or LINKITOM offer excellent waterproofing. For general utility trailers, the MAXXHAUL 70205 provides a complete, easy-to-install LED solution. If you’re on a tight budget, the MAXXHAUL 70094 incandescent kit is a reliable choice.
Remember to prioritize safety and compliance. A well-lit trailer is not just a legal requirement but a crucial part of safe towing. Consider the factors in this guide, and you’ll find the perfect kit to keep you visible and safe on the road.
