Top 14 Boat Trailer Light Reviews

1. MAXXHAUL 70205 12V Trailer Light

It’s the right LED trailer light for me as it’s a full-service kit. It means that it includes the things that you may need, such as the parts for installation. You can have clearance lights, rear reflectors, side reflectors, side marker lights, tail, stop, and turn signal lights.

There’re a license plate bracket, four-way connectors, wire caps, and wiring harness for the installation. The wiring harness is coded in the lengths of 23feet and 4 feet. The wires are covered with UV jackets.

It’s a multi-functional utility trailer, so you can expect good quality from it. Since it’s with a LED light, high visibility is expected. It’s much better than the old school incandescent light as it has a better light quality and can last longer.

Using LED light has many advantages. It needs lower energy compared with the traditional lights yet manifests better performance. Additionally, it produces a bright light that is suitable for being a license plate light. Hence, it’s ideally used for boats, trailers, and campers.

This trailer light kit also promises durability because of its non-corrosive housing. The parts are tough enough to establish a rugged construction. Thus, it can withstand harsh weather. I can attest to that as I’ve used it during rainy and snowy days.

Installation can be done easily as the necessary parts are provided. When doing it, I noticed that the side lens is with standard bulbs. I was unimpressed at first but then realized that I need to double-check some things. It needs to be done to comply with the rigid quality inspection of DOT.

With this pair of lights, it carries out all the functions of trailer lights. It operates as a combination of running and stop lights, license plate light, and turn signal indicator. These things are best applied on a marine boat truck over the 80-inch width of a towing trailer.

I’m amused at how bright it is with the LED lights. The visibility coming from them is not disappointing. Also, they have a longer life span. Traditional incandescent lights can’t beat these abilities.

I checked the LED lights for the sake of being specific. The front part has 12 diodes in the left light, while six diodes are on the sides. The four white diodes that are facing downwards are the license plate lights. There are 18 diodes with the right light on which 12 are in the front and six at the back.

These trailer lights abide by DOT regulations; therefore, it has a rating of IP68 waterproof. The manufacturer sees to it that this feature is flawless. Sonic welding technology is applied, and the 18-inch gauge is made of pure copper wires to make it completely submersible.

Every existing hole is glued to block any elements like water or dust. It has submerged into the water many times, and nothing went inside it. It’s wonderful as its producer is confident enough to provide a 12-month warranty. It seems that I don’t need to claim it.

Buyer’s Guide


You have to know essential factors when searching for trailer lights, whether it’s for an upgrade or replacement. Who doesn’t want to get the worth of their money and be satisfied with what you bought? Divert your attention from false advertising and marketing but rather pay attention to these:

The Type of Light

When you have a boat trailer with a width lower than 80 feet, see to it that you have turn signal lights, tail lights, stop lights, side marker lights, and rear or side reflector.

When you have a boat trailer 80-feet wide and above, it’s best to give importance to clearance lights. These lights need to be on both sides of the trailer. Three, red identification lights are also essential, and they should be placed at the end of the trailer.

Make sure to get a boat trailer light kit that complies with the standards of the law. It should be certified by its high visibility, quality, reliability, and durability. You can have a safe and convenient transporting of the boat with the right type of light.

Covering or Casing

A covering or casing is vital for the protection of the trailer lights. Whenever you use your trailer, it’s inevitable that they are exposed to natural and exterior elements.

Interference from outside factors doesn’t only shorten the lifespan of your light. Disaster can happen as a short circuit. The tough covering that you can rely on is the one that is submersible and waterproof. It is also corrosion-resistant, and it allows the light to withstand bump and impact.

Waterproof quality blocks moisture and condensation, which can degrade the light’s performance. So your trailer lights should have a casing made of marine grade materials.

Ruggedness is a wonderful trait of the covering of trailer lights. It implies that the light and hardware are both tough. They can withstand the wear and tear of outdoor elements. There’s no need to question its durability as it also lengthens the shelf life of the trailer lights.

The Installation

You may find a trailer light kit with everything in it, including the necessary things for installation. Some kits will be easy to install and self-explanatory. Some of them have a complicated wiring system. Therefore, you need some experts working on it.

It’s recommended to buy a kit that is easy and convenient to install. It’s great to have the necessary wires, but it will be nicer if they are in the required length.

Care and Maintenance

Even how heavy-duty or waterproof the boat trailer lights are, they still need care and maintenance. Here are some tips regarding this matter

Checking the wiring

Regular checking of wiring is needed. Some unpleasant things may happen with the lights, but it can worsen with wires. They are connected to the power supply. Disaster can occur when there are some cuts on them like a short circuit.

You have to inspect every part of it even though you have added some protective cover against water. It’s better to be sure than sorry.

Be Attentive on the Condition of the Light and the Bulb

Spending a few minutes checking the light and the bulbs’ condition doesn’t hurt you so it should be a part of maintenance, especially before using the boat trailer. You don’t want to be interrupted in the middle of the road or the water.

It should also be done after replacement. Wires are connected with the light, so it’s another thing that you have to check and see if they’re in the proper place. By doing this step, you will know if there’s a burnt-out bulb or replacement is needed.

Eyeing the Fuse
