What Size Wire for LED Trailer Lights?

When it comes to wiring trailer lights, there are a couple of different elements that must be considered: the type of bulb used, the size of the wire, and the overall voltage of the lighting system. If you're looking to replace or upgrade your existing trailer lights with LED lights, then it's important to know what size wire to use. In this article, we'll explore why the size of the wire should be carefully considered when installing LED trailer lights, and look at a few examples of what types of wires you should use for different types of applications.

Why Wire Size Matters for LED Trailer Lights

Wire size is important for any kind of electrical system, but it becomes particularly important when dealing with LEDs. This is because LED lights require higher voltages in order to function properly. If you use too small of a wire, then it won't be able to handle the increased voltage. On the other hand, if you use too large of a wire, then you're wasting money and resources on something that isn't needed. It's important to find the right balance to ensure that your LED trailer lights will work efficiently and effectively.

The Right Wire Size for Low Voltage LED Trailer Lights

For low voltage LED trailer lights, you'll generally need a wire that is rated for 12 volts. This can be either an 18-gauge or 20-gauge wire. The higher the gauge, the thinner the wire and the lower the resistance. You should also consider the length of the wire when choosing the right size, as longer wires require thicker wires to reduce power loss.

The Right Wire Size for Medium Voltage LED Trailer Lights

For medium voltage LED trailer lights, you'll need a wire that is rated for 24 volts. This should generally be at least 14-gauge but can go up to 8-gauge depending on the length of the wire. Again, the longer the wire, the thicker the wire will need to be to avoid power loss.

The Right Wire Size for High Voltage LED Trailer Lights

Finally, for high voltage LED trailer lights (generally over 40 volts), you should use a wire that is rated for high voltage. This is usually 6-gauge wire but can go up to 4-gauge depending on the requirements of the lighting system.

Conclusion

When wiring LED trailer lights, it's important to carefully consider the size of the wire you use. The size of the wire will determine how much current can flow through it, which is critical for ensuring that your LED lights operate correctly and efficiently. When selecting the right wire size for your LED trailer lights, always consider the voltage rating, the length of the wire, and the type of lighting system you are using. With the right wire size, you can be sure that your LED trailer lights will operate safely and effectively.
