What Are Trailer Lights?

Best Submersible Trailer LightsTrailer lights are lights you install on the back of your boat, truck, camper, or any other trailer. This way, other people can know when you are turning, braking, etc, and act accordingly. Trailer lights help you ensure your safety while towing weights and prevent damage to your property.

Submersible trailer lights are designed to be waterproof and thus, are used for trailer boats. By the way, do you know how important it is to have a pair of the best boat trailer tires? Getting back to our topic, it is principal for trailer lights to be waterproof besides being submergible as you might be needing your trailer during different weather conditions.

If you are looking for a set of high-quality trailer lights for your boat trailer, go for marine-grade lights.

Benefits Of Submersible Trailer Lights

Using trailer lights is as important for your safety but also maneuvering your trailer as well. Here are some of the benefits of using trailer lights, especially LED lights.

1. Safety

If you wouldn’t be using trailer lights, you might be exposing yourself to risk. Lights are designed to give clear signals to other people on the road about your next move. Hauling a trailer covers your vehicle’s lights, which is why you should connect it to trailer lights. Not only trailer lights can prevent collisions but not using them is against the law as well.

2. Durability

Although this applies to LED lights rather than to standard bulbs, you can expect your trailer lights to last for a while either way. However, LED lights can last up to 10 years on average and require no maintenance, which is their biggest advantage in comparison to standard bulbs.

That means you can install your trailer lights and forget about them for another decade. This way, you can save up some money as well.

3. Designed For Marine Use

When loading your boat onto a trailer, you just have to submerge it to a certain extend. Not all trailer lights are submersible but those we reviewed today are. You can submerge them when loading your boat with no worries, which is why you should always opt for specialty products for marine use.

4. Energy-Efficiency

Again, this applies to LED light bulbs rather than standard bulbs LED lights are way more energy-efficient as you don’t have to use as much power as you would with standard bulbs. What is more, LED lights to use up to 10 times less energy than standard bulbs do.

5. Generate Little Heat

You probably already know how easy it is for lights to overheat. Halogen lights can get extremely hot when in constant use for a couple of hours while LED lights stay warm no matter how long you use them. LED lights are more practical, safe to use as they won’t burn your hand, and there is no risk of overheating.

Submersible Trailer Lights Buying Guide

Submersible Trailer Lights ReviewsWhen buying trailer lights, pay attention to the following features if you want to ensure you get the best quality product.

1. Brightness

This is the most important feature of any light. What’s the point of using a light that is not bright enough? When on the road, it is essential for other people to spot your signals in time. LED lights are the best when it comes to brightness and they use very little power so it is a win-win situation.

Although we have managed to find a couple of great and bright trailer lights that come with standard bulbs, LED lights might be a slightly better choice when you are submerging your trailer.

2. Waterproof

Again, you would be submerging your boat trailer and trailer lights into water. If you don’t have a unit that is waterproof, your trailer lights will fail you shortly.

On the other hand, heavy rain can mess up with low-quality, improperly-sealed lights as well. Water can get into the casing easily, which would damage the unit.

This is the second most important thing to look for in trailer lights if you want them to last even after you submerge them into the water multiple times.

3. Quick Draining

We’ve said you should find submergible, waterproof lights. Yet, it is as important to find a unit that boasts quick draining. This will ensure no water can get under the casing or cause damage to wires or bulbs. You can find trailer lights with drilled holes meant for quick water draining that prevent water from getting inside.

4. Corrosion-Resistant

If you are sailing salty seawater, it is essential to find corrosion-resistant trailer lights. Of course, housing and lights are plastic, so you can’t expect them to be resistant to corrosion, while wiring can and should be. Stainless steel is the best material to choose as it is suitable for marine use so try to find trailer lights with stainless steel parts.

5. Ease Of Installation

You don’t have to be a professional to install trailer lights. Replacing bulbs is super-easy so you can do this task with the minimum effort once you’ve installed the unit. Here, it is important to install wiring the right way and attach the unit well so it is not wobbly.

Of course, you have to know some basic skills in electronics or you can ask a friend to help you out with this.

6. Design

Design is a matter of preference. You can find trailer lights in different shapes – round, oval, and rectangular. Some units come with different light intensities, which is a rather attractive feature but not the essential one.

7. Safety Rating

Submersible Trailer Lights Buying GuideAlthough trailer lights are required on the road and you can get a penalty for not using them, the most important thing why you should is – for the sake of your own safety and safety of other people on the road.

As you could see yourself, most of the trailer lights we listed in our reviews are DOT certified, which means they meet the highest safety requirements. If you want to prevent damage to your boat and protect yourself from injuries, go for a unit that holds this safety rating.

8. Fitting

Most trailer lights are designed to fit the boat trailer either under or above 80 inches in width. Make sure to check on the manufacturer’s specs or sizing chart before making a final decision.

How To Install Trailer Lights?

You will need some basic home toolbox and this guide to install trailer lights.

  • Attach and secure your boat trailer so it doesn’t move while you are installing lights to it.
  • Unscrew the original lights, disconnect old wiring, and thread the new one. Attach the wires so none is hanging down. In order not to get a penalty, make sure the cable has some kind of support every 60cm.
  • If there is any excess wiring, trim it off.
  • Strip 1 cm of insulation off the wires with cable strippers.
  • Take your new kit and you will spot one piece for the number plate light. Attach this one first so that your visibility is impeccable at night.
  • Make sure all of the lights are positioned properly and there is equal space between each.
  • Screw-in or set bolts to secure the lights on both sides.
  • Match the same colors on the lights and wires and twist them. Here are the color codes: stop lamps are red, brakes are blue, a left indicator is yellow and the right is green, the reverse is black, earth return white, and finally, rear laps are brown.
  • Tighten the plastic housing but make sure not to damage it.
  • Secure the trailer plug to your vehicle and attach the trailer to the vehicle’s tow bar.
  • Test all of the indicators to make sure you have attached the wires properly.
  • Take a heat gun and seal the joints with a piece of heat shrink. Do this for both sides. The electrical tape would do as well if you don’t have a heat gun and heat shrink.

Maintenance & Safety Tips For Trailer Lights

Maintenance & Safety Tips For Trailer LightsTrailer lights are easy to maintain, just as it is the case with your boat anchors, anchor ropes, or best bilge pumps. Still, the following steps are important to take if you want to preserve your trailer lights in good condition and ensure their long service life.

1. Maintenance Tips

  • If your trailer lights are gleaming, that might be a ground issue. To fix this, ground the wiring by using a trailer hitch from the truck.

Check female and male connections as well. In case you find a broken wire, try to re-connect it with insulating tape or call a professional to handle this.

2. Safety Tips

  • Check the electrical connectors, cables, and wires each time before you hit the road. If something looks suspicious, call a technician.
  • Don’t ever go for a trip if your trailer lights are not working properly.
