Boat Trailer Light Buying Guide

If you were to use a standard horsebox or car trailer light installation kit and bulb construction for your boat trailer, you will run into issues. For starters, the majority are not waterproof or sealed, so water will get into the lenses straightaway. On top of this, the wiring will not be friendly with saltwater, which means they will corrode in very little time.

Ensuring you purchase a high quality marine LED trailer light setup is crucial if you want them to last many years. Below are some factors that you should consider when searching for marine trailer LED lights.

Trailer Light Hardware

Many people will spend a large amount of money on a high quality LED trailer light but buy cheap with the hardware. This is a huge mistake as the hardware and wiring is the most important part and you will only end up having to rewire it at a later date.

Mounting hardware needs to be able to withstand saltwater with stainless steel being the most desirable. The wiring is even more important with a marine grade tinned wire being the best way to wire lights for boat trailers.

It is so tempting to go cheap with the hardware and wiring but this is the one part of the whole setup that requires high quality materials.


The installation of submersible trailer lights can vary from trailer to trailer but it is the wiring and preparation that is the most time consuming part. Installing the LED lights for the boat trailer is relatively straight forward and in most cases a direct replacement.

When wiring the lights, you will want to think long term and to do this, you should ensure you are waterproofing the connections if you plan on submerging the boat trailer.

The best way of doing this is by having all lights having a separate ground wire to a junction box, the lights themselves having shrink wrap connectors and then adding liquid electrical tape as a safety measure. Preparation is key and taking your time during wiring will pay off when you hear about people rewiring every other year.

Design and Dimensions

You can be as unique as you want when it comes to trailer lights and there are many designs to choose from. Many people prefer a low profile and boxy shape whereas others prefer the oval design that compliments their boat.

Regardless, before buying ensure you take measurements to prevent wasting your time and realizing they won’t work or fit correctly.


Even though upgrading your boat trailer lights is cheap and easy to do, it makes a huge difference to the overall appearance. Bright LED trailer lights are the first thing people will notice as you back the boat into the ocean or travelling down the highway.

Investing into a top rated marine trailer light that comes with stainless steel hardware and marine grade wiring is advised. All of the above are highly rated throughout the boating community and are submersible when installed correctly.
