Are you looking to bring some light and visibility to a golf cart? Wiring 12-volt lights to a 36-volt electric vehicle can be an intimidating task, but with the right information and tools, it doesn’t have to be complicated.

In this blog post, we will provide step-by-step instructions on how to wire 12-volt lights correctly and tips for success. Whether you are using LED lighting or traditional halogen fixtures, these steps should give your golf cart the illumination it needs for safe driving on any course. Let’s get started!

Understanding 12 Volt and 36 Volt Electrical Systems

Electrical systems can be complex, especially when it comes to volts. Two common voltages that you may encounter are 12 volts and 36 volts. But what are the differences and what do you need to know?

When it comes to 12-volt systems, they are commonly used in cars, trucks, and boats. They are relatively straightforward and easy to understand, making them a popular choice for DIY projects.

On the other hand, 36-volt systems are commonly found in golf carts and electric vehicles. While they may seem intimidating at first, they offer increased power and efficiency. By understanding the differences between these two systems, you can ensure you choose the right one for your needs.

Connecting the Wires to The Golf Cart Light Fixture

The next step in wiring your 12-volt lights to a 36-volt golf cart is connecting the wires correctly. You will need two pieces of wire: one for the positive terminal and one for the negative terminal. The positive wire should be connected to the light fixture’s red (positive) terminal, while the negative wire should be connected to the black (negative) terminal. It’s important to use proper safety measures when dealing with electricity, such as wearing safety goggles and gloves during installation. Once your wires are securely attached, you can proceed to the next step.

Mounting the Light to the Cart

When it comes to rolling your cart around in low light settings, having a mounted light can make all the difference. But how do you go about mounting that light, exactly? Fortunately, it’s not as complicated as you might think. You can easily secure your light to the cart with just a few basic tools and some simple steps.

Whether you’re hauling equipment around in a warehouse or simply trying to navigate a dimly-lit parking lot, having a reliable light source can give you the visibility you need to get the job done. So why struggle with carrying a flashlight or trying to light your way with your phone? Mounting your light to your cart is quick, easy, and well worth the effort.

Tips for Safety When Installing Lights on Golf Carts

Golf carts are a convenient way to get around the golf course, especially at night. However, taking safety precautions when installing lights on your golf cart is important.

First, make sure the lights are securely attached to the cart and won’t become loose or fall off while driving. Using the correct wiring and ensuring it’s properly insulated is also crucial to avoid electrical hazards.

Always follow the manufacturer’s instructions and recommendations, and avoid making any modifications or DIY installations. Lastly, be sure to use the lights responsibly, avoiding any distractions or unnecessary use while driving or operating the golf cart. By following these tips, you’ll be sure to have a safe and enjoyable ride on your golf cart.


In conclusion, properly installing lights on a golf cart requires a thorough understanding of both 12 Volt and 36 Volt electrical systems as well as the tools and parts necessary for the job. While connecting the wiring to the light might seem complicated at first, being careful and precise is an important step of this process.

After mounting the light to your cart you should always be sure to troubleshoot before driving in case of any unseen problems. Finally, always triple-check all connections and those involving power lines for any risk of injury rather than having assumptions about safety. With these steps and tips in mind, your experience in installing golf cart lights will go smoothly.
