The Importance of 4 Wire Trailer Lights

I have been an avid traveler for years and one thing I have learned is the importance of having proper lighting on my trailer. Specifically, having 4 wire trailer lights has been a game changer for me and has made my travels much safer and more convenient.

Firstly, having 4 wire trailer lights ensures that all the essential lights on your trailer are functioning properly. This includes the brake lights, turn signals, tail lights, and license plate light. These lights are crucial for signaling to other drivers on the road and ensuring that your trailer is visible in all conditions.

Moreover, with 4 wire trailer lights, you have the option to add additional features such as reverse lights or hazard lights. These extra features can be extremely useful in certain situations, such as backing up in a dark area or alerting other drivers of an emergency situation.

Another reason why 4 wire trailer lights are necessary is for safety reasons. In many states and countries, it is illegal to operate a trailer without proper lighting. Not only can this result in hefty fines, but it also puts yourself and others on the road at risk. Having all the necessary lights functioning properly can prevent accidents and keep everyone safe.

My Buying Guide on 4 Wire Trailer Lights

As someone who has recently purchased and installed 4 wire trailer lights for my own trailer, I understand how overwhelming it can be to navigate through all the options and features available. That’s why I have put together this buying guide to help you make an informed decision when purchasing 4 wire trailer lights.

What are 4 Wire Trailer Lights?

Before diving into the buying guide, it’s important to understand what exactly are 4 wire trailer lights. These lights are typically used for trailers that have four main functions – brake lights, turn signals, tail lights, and ground wire. The four wires are color-coded – brown for tail lights, yellow for left turn/brake lights, green for right turn/brake lights, and white for ground wire.

Types of 4 Wire Trailer Lights

The first thing to consider when buying 4 wire trailer lights is the type of light you need. There are two main types – incandescent and LED.

  • Incandescent: These are the traditional type of trailer lights that use a filament inside a glass bulb to produce light. They are more affordable but tend to burn out faster compared to LED lights.
  • LED: LED (Light Emitting Diode) trailer lights use less energy and have a longer lifespan compared to incandescent lights. They also provide brighter and clearer lighting which can increase visibility on the road.

Budget

The next factor to consider is your budget. While LED trailer lights may be more expensive upfront, they will save you money in the long run due to their longer lifespan and energy efficiency. However, if you have a tight budget or don’t plan on using your trailer frequently, incandescent lights may be a more affordable option.

Durability and Weather Resistance

If you frequently use your trailer in harsh weather conditions or off-road situations, durability and weather resistance should be top priorities when choosing 4 wire trailer lights. Look for lights that are made with high-quality materials such as corrosion-resistant housing and waterproof wiring connections. LED lights tend to be more durable compared to incandescent ones.

Ease of Installation

The last thing you want is spending hours trying to install your new trailer lights. Look for ones that come with easy-to-follow instructions or even better, pre-wired connectors that can plug directly into your existing wiring harness. This will save you time and frustration during installation.

Additional Features

Sometimes it’s the little extra features that make all the difference in choosing between different brands or models of 4 wire trailer lights. Some additional features you may want to consider include built-in reflectors for increased visibility, rubber grommets for added protection against vibrations, or multi-function capabilities such as combining brake light and turn signal functions into one light.

In Conclusion

I hope this guide has helped make your decision-making process easier when purchasing 4 wire trailer lights. Remember to consider factors such as type of light, budget, durability/weather resistance, ease of installation, and additional features before making your purchase. With the right set of 4 wire trailer lights installed on your trailer, you can ensure safe travels on the road ahead!
