Summary: Wiring lights on a 48-volt golf cart is an essential upgrade that enhances the cart’s safety and functionality by providing better visibility during nighttime or low-light conditions. The process involves connecting the lights to the golf cart’s electrical system while ensuring proper voltage and wiring to avoid damaging the components. Before starting the installation, gather the necessary tools and materials, such as a wiring harness, voltage reducer, lights, wire strippers, a multimeter, and a drill or screwdriver.

First, install the voltage reducer to step down the golf cart’s 48-volt power supply to a suitable voltage for the lights, typically 12 volts. Connect the voltage reducer to the golf cart’s battery bank, following the manufacturer’s instructions. Ensure that the positive and negative wires from the voltage reducer are correctly connected to the battery terminals to avoid damaging the lights.

Next, mount the headlights and taillights onto the golf cart, using the provided brackets and hardware. Route the wiring harness from the lights to the voltage reducer, securing the wires along the cart’s frame with zip ties to prevent them from getting tangled or damaged.

Connect the wires from the lights to the voltage reducer, making sure to match the positive and negative terminals. Finally, install a switch to control the lights and connect it to the wiring harness. After completing the installation, test the lights to ensure they function correctly and make any necessary adjustments. By following these steps, you can successfully wire lights on a 48-volt golf cart, enhancing its usability and safety.

Few Things to Consider Before Wiring Lights on a 48 Volt Golf Cart:

Position of the Light

You will need to decide where you want to position your light before you can wire it up. You can mount the light near the front of the golf cart or near the back.

You can also put it under the seat or in any other location that you think would be suitable. Most golf carts have a built-in storage compartment perfect for housing a light fixture.

Remember that the light must be positioned so the driver and passengers can easily see it. If you’re unsure where to mount your light, consult the owner’s manual for your specific golf cart model.

Type of Light Fixture

There are several different types of light fixtures available for golf carts. You can choose from LED, halogen, or even fluorescent lights. Each type of light has its advantages and disadvantages. And the price range also differs from each other.

When choosing a light fixture for your golf cart, you must ensure that it is durable and can withstand the elements. A good light fixture should also provide enough light to make the driver and passengers visible at night.

Source of the Power Supply

Next, you need to consider the power source for your light fixture. For example, most golf carts run on 48-volt batteries. And if your golf cart has a built-in storage compartment, it likely already has a 12-volt outlet. If not, you can easily install one yourself.


You will just need to purchase a 12-volt adapter and wire it to the battery. To wire the light directly to the battery, you must use a 48-volt to 12-volt converter.

You can also use a double battery (sing battery for each light) to make your light stable for a long time. But be sure to use batteries of the same age and condition to avoid damaging your light fixtures.

Size & Shape of the Lights

When it comes to the size and shape of the lights, you must ensure that the light fixture you choose is not too big or too small for your golf cart. Second, you need to decide if you want round or rectangular lights.

You also must ensure that the light output (lumens) is appropriate for your needs. If you choose a light that doesn’t fit properly or doesn’t produce enough light, it could cause problems while driving. So there’s no point in buying a light that’s not suited for your golf cart.

Step by Step Procedure: How to Wire Lights on a 48 Volt Golf Cart

Step 1: Turn off the Cart Engine

Before working on the wiring, turn off your golf cart’s engine. This will prevent any accidents while you’re working on the wiring.


You must ensure the engine is off and the key is out of the ignition before starting to work. If your cart has a 48-volt battery, make sure it is disconnected.

Step 2: Mark the Installation Area

Next, you need to mark the installation area for the lights. You can do this by measuring the length and width of the light mounting brackets.

Once you have the measurements, use a pencil or marker to draw a line on the cart’s body where you’ll be installing the lights. This will help you know exactly where to drill the holes for the brackets.

Step 3: Open the Battery Compartment

Now, you need to open the battery compartment to access the wires. Most golf carts have two battery compartments, one on each side of the cart.

You’ll need to open both compartments to get to all of the wires. Once you have the compartments open, look at the wiring diagram that should be inside. This will help you identify which wires you need to work with.

Step 4: Splice the Wires

Next, you’ll need to splice the wires to connect the lights. You can do this by using a wire stripper to remove about ½ inch of insulation from the end of each wire.

Once the insulation is removed, twist the wires together and use a wire connector to secure them. Again, make sure you twist the wires together tightly, so they don’t loose.

Step 5: Attach a Voltage Reducer

If your golf cart has a 48-volt battery, you’ll need to attach a voltage reducer before connecting the lights. This will prevent the lights from burning out too quickly.


To attach the voltage reducer, connect the positive wire from the reducer to the positive wire from the battery. Then, connect the negative wire from the reducer to the negative wire from the battery.

Step 6: Close off the Wire Voltage Reducer

After wiring the voltage reducer, you need to close off the wire. This will help protect the connection from water and other elements.

To close off the wire, use electrical tape or heat shrink tubing to cover the connection. You can also use butt connectors or wire nuts to close off the voltage reducer. This will prevent any shorts from happening in the system.

Step 7: Connect the Wires to the Lights

Now, you can connect the wires to the lights. Start by connecting the positive wire to the positive terminal on the light.

Then, connect the negative wire to the negative terminal on the light. Ensure all the connections are tight so the wires don’t loose. If your lights have a ground wire, connect that to a metal part of the golf cart frame.

Step 8: Drill the Mounting Holes

Now, you need to drill the holes for the light mounting brackets. Take your time when drilling the holes so they’re the right size for the brackets. You need to ensure that the brackets fit snugly in the holes so they don’t move around.

Step 9: Attach the Lights to Mounting Brackets

After drilling the holes, you can now attach the lights to the mounting brackets. Start by placing the bracket over the hole and securing it with screws.


Make sure the bracket is tight, so the light doesn’t move around. Also, connect one lead of the inline fuse holder with the corresponding lead from the light’s voltage reducer. Close off the other lead to the fuse holder with butt connectors.

Step 10: Test the Lights

Once you have the lights installed, it’s time to test them. First, turn on the golf cart’s engine and then turn on the lights.

If they’re working properly, you’ll see a bright light shining from each one. If not, check all the connections to make sure they’re tight. You may also need to check the bulbs to see if they need to be replaced.
