Types of Trailer License Plate Lights

LED License Plate Lights

LED lights are increasingly popular due to their energy efficiency and longevity. They consume less power compared to incandescent lights, making them ideal for trailers that are often in use. The brightness of LEDs enhances visibility, especially in low-light conditions, ensuring that your license plate is always readable, regardless of the time of day.

Incandescent License Plate Lights

While newer technology has shifted towards LEDs, incandescent lights remain a viable option for many trailer owners. They are typically more affordable upfront. However, they have a shorter lifespan and consume more energy than their LED counterparts. If you’re on a budget and your trailer is not used frequently, incandescent lights can still be a suitable choice.

Universal License Plate Lights

Universal license plate lights are designed to fit a variety of trailers. They are easy to install and are ideal for DIY enthusiasts. Their flexible design allows them to be mounted in different positions, making them suitable for a wide range of applications. If you own multiple trailers or frequently change setups, universal lights can provide you with the versatility you need.

Integrated License Plate Lights

These lights are part of the trailer’s assembly, offering a sleek and modern look. Integrated lights are common in newer trailer models and often feature advanced designs that enhance both aesthetics and functionality. If you’re purchasing a new trailer, consider opting for one with integrated lighting for a clean, finished appearance.

Submersible License Plate Lights

If your trailer is used in water, such as a boat trailer, submersible license plate lights are essential. These lights are waterproof and designed to withstand harsh marine environments. They ensure that your trailer remains compliant with road regulations, even when exposed to the elements.

Installation Guide for Trailer License Plate Lights

Installing trailer license plate lights can be a straightforward process if you follow these steps:

1. Gather Your Tools: You will need basic tools such as a screwdriver, wire cutters, and electrical tape. Depending on the type of light you choose, additional tools may be necessary.

2. Remove Old Lights: If you’re replacing an existing light, carefully remove it by unscrewing it from its mounting position. Disconnect the wiring harness.

3. Connect New Lights: Following the manufacturer’s instructions, connect the wiring of your new light. Typically, this involves matching the positive and negative wires.

4. Mount the Light: Secure the new light in place using screws or adhesive as required. Ensure it is positioned correctly to illuminate the license plate.

5. Test the Lights: Before finalizing the installation, test the lights to ensure they function correctly. If they do not illuminate, double-check your connections.

6. Secure Wiring: Once confirmed, secure any loose wiring with electrical tape and ensure that everything is weatherproofed, especially if you’re using submersible lights.

Maintenance Tips for Trailer License Plate Lights

To ensure the longevity and functionality of your trailer license plate lights, follow these maintenance tips:

1. Regular Inspections: Check your lights regularly for any signs of wear or damage. Look for cracks in the lens or frayed wires.

2. Clean the Lens: Dirt and grime can accumulate on the lens, diminishing light output. Use a soft cloth and mild cleaner to keep the lens clear.

3. Secure Connections: Ensure all electrical connections are tight and corrosion-free. Use dielectric grease to help prevent corrosion.

4. Replace Burnt Out Bulbs: If using incandescent lights, replace burnt-out bulbs promptly to ensure compliance with road regulations.

5. Check for Moisture: For submersible lights, inspect for any signs of moisture ingress. If found, replace the light to avoid electrical issues.
