Hey guys! Ever wondered how to keep your trailer lights shining bright, even when they're taking a dip? Let's dive into the world of submersible trailer running lights. These aren't just any lights; they're specially designed to withstand being underwater, ensuring you stay safe and legal on the road, especially when launching or retrieving your boat. Choosing the right submersible lights involves understanding their features, installation, and maintenance.

Understanding Submersible Trailer Lights

First, let's get the basics down. What makes submersible trailer lights different? Well, it's all about their construction. Unlike regular lights, these are sealed to prevent water from seeping in and causing corrosion or short circuits. This is crucial because, as you know, water and electricity don't mix! When selecting submersible lights, consider the following:

  • Waterproof Rating: Look for lights with a high IP (Ingress Protection) rating, such as IP67 or IP68. These ratings indicate the level of protection against dust and water immersion. IP67 means the light can be submerged in up to 1 meter of water for 30 minutes, while IP68 means it can withstand even longer and deeper submersion.
  • LED vs. Incandescent: LED lights are generally a better choice for submersible applications. They're more durable, energy-efficient, and longer-lasting than incandescent bulbs. Plus, LEDs produce a brighter light, improving visibility on the road. LEDs are also less prone to heat buildup, which can damage the light's housing and seals.
  • Wiring and Connections: The wiring and connections are just as important as the lights themselves. Make sure the wiring is marine-grade, meaning it's tinned copper that's resistant to corrosion. The connections should also be waterproof, using heat-shrink connectors or other sealing methods to keep moisture out. Trust me, investing in quality wiring now will save you headaches down the road.
  • Compliance: Ensure the lights comply with all applicable federal and state regulations. This usually means they need to be DOT (Department of Transportation) approved. DOT-approved lights have been tested and certified to meet specific standards for brightness, visibility, and durability.

Step-by-Step Installation Guide

Alright, now let's get our hands dirty! Installing submersible trailer lights might seem daunting, but with the right tools and a little patience, you can totally do it yourself. Here's a step-by-step guide to help you through the process:

  1. Gather Your Tools and Materials:
    • Submersible trailer light kit
    • Wire stripper/crimper
    • Heat gun
    • Heat-shrink connectors
    • Electrical tape
    • Multimeter
    • Drill with various bits
    • Screwdrivers
  2. Remove Old Lights: Carefully disconnect and remove the old trailer lights. Take note of how they were wired to make the installation of the new lights easier. If the old lights are heavily corroded, you might need to use a penetrating oil to loosen the screws or bolts.
  3. Prepare the Wiring: Strip the ends of the trailer's wiring and the new light's wiring. Use the wire stripper to remove about ½ inch of insulation from each wire. Be careful not to nick or cut the wires, as this can weaken them and lead to corrosion.
  4. Connect the Wires: Use heat-shrink connectors to connect the wires. Slide a heat-shrink connector over one wire, then twist the two wires together. Use the crimper to crimp the connector securely. Then, use the heat gun to shrink the connector, creating a waterproof seal. If you don't have heat-shrink connectors, you can use regular connectors and then wrap them tightly with electrical tape. However, heat-shrink connectors provide a much better seal.
  5. Mount the Lights: Mount the new lights to the trailer, ensuring they are securely attached. Use the screws or bolts provided in the light kit. Make sure the lights are properly aligned and positioned according to the manufacturer's instructions.
  6. Test the Lights: Before hitting the road, test the lights to ensure they are working correctly. Connect the trailer to your vehicle and turn on the lights. Check all the lights, including the running lights, brake lights, and turn signals. Use a multimeter to check the voltage at each light to ensure they are receiving adequate power. If any lights are not working, double-check the wiring and connections.

Pro Tips for Installation

  • Use Dielectric Grease: Apply dielectric grease to all electrical connections to prevent corrosion. This grease is non-conductive and will protect the connections from moisture and contaminants.
  • Route Wires Carefully: Route the wires carefully, keeping them away from sharp edges and moving parts. Use zip ties or wire clamps to secure the wires and prevent them from chafing.
  • Check Ground Connection: Ensure the trailer has a good ground connection. A poor ground connection can cause all sorts of electrical problems, including dim lights, flickering lights, and blown fuses. Clean the ground connection with a wire brush and apply dielectric grease to prevent corrosion.

Key Features to Look For

When shopping for submersible trailer lights, keep an eye out for these key features:

  • Fully Sealed Construction: The lights should be completely sealed to prevent water from entering. Look for lights with a seamless design and high-quality gaskets.
