Buying Guide – How to Choose the Best LED Trailer Light Kit
Selecting the right LED trailer light kit involves evaluating several technical factors to ensure safety and longevity. Consider how your trailer is used and what environments you frequent.
Waterproof Rating
The waterproof rating determines how well the lights resist water damage. Look for IP67 or IP68 ratings if you launch boats or tow through deep water. These ratings ensure the internal circuitry remains sealed against moisture intrusion.
Higher ratings mean better protection for harsh conditions.
Wiring Harness Quality
The wiring harness is critical for long-term reliability. Kits with braided nylon sheaths or UV-coated wires resist fraying and sun damage. Avoid standard bare PVC wires if you tow in harsh environments regularly.
Invest in kits with heavy-duty harnesses.
DOT Compliance
Ensure the lights meet DOT FMVSS 108 standards. Legal compliance ensures your vehicle is road-legal and safe. Non-compliant lights can lead to fines or failed inspections.
Always check for certification claims in the product description.
Mounting Hardware
Hardware quality affects how securely the lights stay in place. Stainless steel brackets and screws resist rust and vibration damage. This prevents loose connections that could cause signal issues on the road.
Choose kits with rust-proof mounting options.
LED Brightness
Brightness impacts visibility during night driving. Higher lumen outputs ensure your signals are clear to others. Look for kits with multiple diodes per light for maximum illumination.
Brighter lights improve overall safety significantly.
Light Functions
Different kits offer varying combinations of stop turn and marker lights. Ensure the set includes all necessary functions for your trailer type. License plate lighting is often an overlooked but essential feature.
Verify all required functions are included in the box.
Installation Ease
Simplified wiring diagrams and color-coded wires reduce installation time. Kits with pre-soldered ends prevent messy connections for beginners. A clear guide ensures you connect wires correctly without frustration.
Look for kits with clear instructions included.
Durability Features
Build materials like ABS plastic resist cracking from road debris. Sonic welding seals can prevent leaks better than glue in marine environments. These features extend the lifespan of the lights under tough conditions.
Prioritize rugged construction for long-term use.
How to Use and Care for Your LED Trailer Light Kit
Install the lights according to the manufacturer's diagram to ensure correct wiring. Secure all connections tightly and check for shorts before driving.
Clean the lenses regularly with mild soap to prevent dirt buildup. This maintains optimal brightness and ensures clear signaling to other drivers.
Inspect the wiring harness periodically for signs of wear or cuts. Replace damaged sections immediately to avoid electrical failures while towing.
Frequently Asked Questions
Are LED trailer lights brighter than incandescent?
Yes LED lights are significantly brighter and illuminate faster than incandescent bulbs. They offer better visibility in rain or fog due to higher output diodes.
Can I install these myself?
Most kits are designed for DIY installation with color-coded wires. Basic tools and a wiring diagram are usually sufficient for a complete setup.
Do I need to buy a separate wiring harness?
Some kits include a complete harness while others do not. Always check the product specifications before purchasing to ensure you have all necessary wires.
What does IP68 mean for trailer lights?
IP68 means the device is fully dust-tight and can be submerged in water. It is ideal for boat trailers that frequently enter water during launches.
How long do LED trailer lights last?
LEDs generally last tens of thousands of hours compared to standard bulbs. They are more resistant to vibration and impact which extends their lifespan.
Are these kits universal for all trailers?
Most are designed for trailers under 80 inches wide. Check the fitment details to confirm compatibility with your specific vehicle setup.
Do I need to change fuses when upgrading?
LEDs use less power so existing fuses usually work. If you add many lights you may need a higher amperage fuse for safety.
Can I use these for deep water submersion?
Only lights with IP68 ratings are suitable for deep submersion. Others are water-resistant but not designed for full underwater use.
