Wiring is an important safety element on your trailer.
If you are pulling a trailer you know how important lighting is on this vehicle.
When you are purchasing a new or used trailer, you would be wise to get an expert to help you check out the wiring. The wiring should be fastened well to the main frame of the trailer so it doesn’t get the opportunity to hang. If you find any wires that are hanging this cannot be good. A hanging wire can be caught on something when you are backing into or out of your drive.
You might not have problems for a while, but consider how this will might be a problem in a few weeks or months.
Check how the wiring is attached to the trailer. Does it look like something that will last?
Besides checking whether the wiring will drag or fall, see how the wiring connections are made off of the main harness.
Some companies will use black electrical tape. Other companies use connectors that are plastic cases filled with silicone. You want to lessen the likelihood that the connections will hold up and there won’t be shorts in your trailer. A short can become a nightmare if your lights disappear on you some night.
The quality of lights can also vary. LED stands for Light Emitting Diodes and they do have some advantages over the incandescent bulbs used in later models. You should try to get a trailer with LED lights. Lights that are a little larger means you don’t have as much chance of getting hit as you are using your trailer.
