Do you make a complete kit to add interior light to a cargo trailer. Currently no electrical inside the trailer. Is a 7 wire plug system.

Helpful Expert Reply:

While we do not have a complete wiring kit for your interior light for a cargo trailer, you can simply use 16-gauge wire # 16-1-1 to install the light into the 12v power pin on your junction box. This solution provides power only when the 7-way plug is plugged in.

If you need an interior light option, I suggest the Peterson Great White LED Trailer Interior Cove Light - 1000 Lumens - 18" Long # 359-3. Depending on the size of your trailer, you can always add more than 1 of these lights for more visibility. I went ahead and attached a photo of these lights being used in an enclosed cargo trailer.
