Utility trailers

Whether you use your trailer at night, or you just want add some wow factor for on the road, our LEDs are up to the task. Our profile and strip will combine to create fully waterproof fixtures. Because of this you can install them on the outside of your trailer, not just the inside. We also have the ability to resin fill the Roma. This produces a fixture that is waterproof to the point that it can be fully submerged in water for no limit of time.

Why use the Roma LED channel?

We consider the Roma to be our LED channel most suited to interior trailer lighting for two reasons. One, it creates a waterproof fixture, something that we would consider a requirement for any trailer lighting. Two, its simplicity makes it highly versatile.

We sell the Roma with a 10-year guarantee, and our compatible diffusers have a 4-year guarantee. That's how confident we are in its quality. With the Roma, you won't need to worry about interior trailer lighting again for a long time.

Why use our Trailer Series waterproof 12V LED strip?

We recommend this LED strip for 12V LED interior lights, for four simple reasons.

  1. The Trailer Series LED strip has an IP68 waterproofness rating.
  2. 12-volt rating matches the voltage of the majority of semi-trucks and trailers.
  3. High quality strip made in Europe. Comes with a 3-year warranty.
  4. High energy efficiency of LEDs provides ample light without draining your battery.

The Trailer Series strip produces a powerful white light that will light up every corner of your trailer. Note that the LED light strip is dimmable, so when installed with a dimmer you can adjust the brightness to your preference. This way you can produce accent lighting, if so desired.

Light sensor for 12V trailer interior lights

We said earlier why set up a work light when you can flip a switch. Now we say, why flip a switch when you can have your lights turn themselves on. The Blebox Miniature Light Sensor will automatically turn on the LED lights in your truck interior when you open the back doors.

The sensor can take 12-24V making it compatible with our Trailer Series LED strip. For best results try to install it close to the door. This way it can easily detect the change in light.

It's also easy to install. See this quick tutorial video;

Battery powered LED trailer lights

How will you turn on your LED trailer light if you haven't hitched up your vehicle? If this is something you want to do consider our Power Tool Battery Adaptor. Simply slot a 12V Dewalt battery or equivalent into the adaptor and illuminate your enclosed trailer.

Please make sure to use a 12V battery otherwise you could blow the Trailer LED strip. Also make sure to never power your lights from the vehicle and the battery at the same time. Remember, the LED interior lights are only 12V. Powering from the vehicle and the battery simultaneously will blow your LED light strip.

Use batteries like this.

Waterproof your 12V LED interior lights

The Roma and Trailer Series LED strip are great for semi-truck interior lighting because they're waterproof. Just take note that their ratings are not automatic: steps are required to achieve waterproofness.

On the LED strip add silicone to any uninsulated wiring. The most important areas are the solder joints.

To seal the Roma, you'll need to use its compatible end caps. Use our LED sealant to attach and waterproof the end caps. Also make sure to fill any holes made to run wiring with silicone.

Q: Do I need to use a power supply with LED light strips for semi-trucks?

A. No. Almost all semi-trucks in the USA use a 12-volt battery. Therefore, the power running to the trailer is also 12V which is perfect for our Trailer Series LED Strip. 24V batteries are quite common in international trucks. If this is the case with your truck you'll need to transform the power down to 12 volts with a power supply.

Q: Will these interior lights run my battery flat?

A. Yes, they will after some time, if your vehicle's engine is not running. Consider using the power tool battery adaptor to power your strip without burning fuel. Don't power the strip with your car and a battery simultaneously, or you will overload it and cause failure.

A. Yes, use our Power Tool Battery Adaptor to light up your trailer with DeWalt and DeWalt-equivalent batteries.

Q: Will these LEDs work in a refrigerated truck?

A. Yes, LEDs are well suited to reefers. They function perfectly in cold temperatures. LEDs emit about 12 times less heat than other light types, which means less energy used on keeping your trailer cold.

Q: Are LED interior lights worth it?

A. Yes, LEDs consume less energy, saving you money. They emit less heat, increasing safety. And they are easy to install in your commercial truck.
