Buying Guide – How to Choose the Best LED Trailer Light Kit

Selecting the right kit depends on your trailer type and usage. Consider waterproof rating wire length and component count before purchasing.

Waterproof Rating

Look for IP67 or IP68 rated lights if you launch boats frequently. IP67 resists immersion up to one meter for 30 minutes while IP68 handles deeper and longer submersion. Standard lights are often just rain resistant and fail underwater.

Choose higher ratings for marine use to avoid short circuits and corrosion.

Wiring Harness Length

Measure your trailer from tongue to rear to find required length. Most kits offer 22 to 25 feet. If your trailer is long consider buying an extension or a kit with extra wire to avoid splicing.

Longer harnesses reduce tension and prevent wire breakage during towing.

Mounting Style

Square vs round mounts must match existing holes. Some kits include gaskets for sealing. Check if mounting hardware is stainless steel to resist rust on wet trailers.

Use proper gaskets to keep water out of screw holes.

Function Count

Standard kits include stop turn and tail lights. More advanced kits add reverse or marker lights. Ensure your kit meets local laws for clearance and identification lights.

Verify legal requirements for width and light color.

Harness Protection

Braided or UV-coated wires last longer than bare PVC. Look for pre-soldered ends to avoid loose connections. A reinforced connector prevents corrosion at the plug point.

Prioritize durable wire jackets for rough road use.

LED Brightness

Higher lumen output improves night visibility. Check if side markers are included. Quality LEDs should turn on instantly without warm-up time.

Select bright lights for safe night driving.

Legal Compliance

Ensure lights meet DOT FMVSS 108 standards. Non-compliant lights can result in fines. Many kits include amber reflectors for side visibility.

Always choose DOT approved kits.

Warranty

Check for 12-month or longer warranties. Some brands offer support for water damage. Good warranty terms indicate manufacturer confidence.

Keep receipts for warranty claims.

How to Use and Care for Your LED Trailer Light Kit

Always inspect the harness before towing for cracks or fraying. Secure connections with electrical tape if needed. Keep connectors dry by applying dielectric grease before plugging in to prevent corrosion over time.

After submerging rinse lights with fresh water to remove salt. Check drain holes are clear if your model has them. Tighten mounting screws after first few uses as they may settle.

If lights flicker test ground connections first as poor grounding causes most issues. Clean contact points with a wire brush. Replace fuses if needed and verify wiring colors match your vehicle.

Frequently Asked Questions

Are LED trailer lights worth the extra cost?

Yes LED lights last longer and use less power than incandescent bulbs. They turn on instantly and provide better visibility. Over time they reduce replacement costs making them a cost-effective choice.

Can I use submersible lights for road trailers only?

Yes submersible lights work perfectly on road trailers. The extra waterproofing adds durability against rain and splashes. They are a safe choice for any towing application.

Do I need to replace the fuse in my tow vehicle?
