What Are Trailer Lights
Boat trailer lights are the lights you can find on the back of any trailer. Submersible lights must handle the conditions underwater, which means they should be waterproof and impervious to erosion also. All trailers require lights on them and on the off-chance that you’re taking off to the water, you have to ensure those lights are marine grade.
Benefits Of Using Trailer Lights
Trailer lights are a legitimate requirement as trailers hinder the line of sight to your vehicle’s lights so a driver behind you would have no idea what are you going to do. They are additionally valuable when you are backing up your vessel into the water. The reason you need marine-specific lights is because of the waterproofing and erosion resistance.
Trailer lights are a secondary part out of a plethora of marine supplies and tools, but they are still essential. Here we are going to show you some of the most critical features when you are looking for your perfect item.
- Brightness – LED lights are your best option here if you aim at having top brightness levels. Their lifespan is pretty impressive too. A set of LED lights may last you 2 full years.
- Corrosion resistance – Saltwater destroys anything. Trailer lights are no exception to this rule and this is why you want to have a product that will resist corrosion. Rust is also something to watch out for. The quickest way for your lights to be destroyed is because of the wire. The lights and bulbs themselves are typically made of glass and plastic. They will be fine. But the wire may be problematic and we recommend that you make sure it is corrosion-resistant.
- Watertight – It would be irresponsible if you got trailer lights that are not waterproof. Splashes of water will occur and you want to be prepared. Accidents are also a possibility and sometimes trailers get submerged. You don’t want to change your whole electrical system of the trailer after a trip to the lake, right?
Installation of submersible trailer lights on your trailer is just as easy as installation of an anchor rope or chain Some people will advise you to leave the existing wiring if you only need to change a bulb. This is generally true but we will go back to our point about the wires being corrosion-resistant. If they aren’t – change the wires as well.
Once you are done changing lights and have sealed them back, you want to make sure that they are watertight again. This is why we recommend getting a mechanic to change them for you if you are not confident in your skills.
There is nothing difficult or complicated about maintaining your trailer lights. It is as simple as taking care of the portable fuel tank. See how you can obtain a great fuel tank by visiting our article on them. Here are some tips and some information about how you can fix some problems with trailer lights, that may help you.
- The ground is the first segment of legitimately working trailer lights. Gleaming lights on the trailer is generally a ground issue.

- Rinse the lights with water and mild soap. The dust on the surface of the lights is dangerous and sometimes can lead to overshadowing. The drivers behind you will not know what are you going to do.
- Always check the wires and the cables, the trailer wiring diagrams will help you a lot.
- If some of the connectors are broken, replace them.
- Check all electrical connectors. If you have some doubts, call a technician.
- Never leave wires dangling from your trailer. They can get on weeds and different objects and force-free. They can be tidied up effectively by utilizing a few zip ties. This is especially significant close to the lights themselves and around the tag. Check your connectors on the vehicle and trailer frequently for exposed or broken wires. Depending on the type of connector—round or flat—check both the male and female connections too. Clean up corrosion or dirt on links with lightweight oil.
