Your cart’s headlights allow you to see obstacles in your way after the sun goes down, enabling safer driving and preventing accidents. But this only works when everything operates as intended.

Why Don't My Golf Cart Lights Work?!

Since each golf cart is unique in what parts are installed, and how the electrical system is set up, there could be several reasons why your golf cart lights don’t work. The bottom line is, you're in the dark and we're here to fix that. For this article, we're going to shed some light on the top instances that may answer this all-too-frustrating question, and get you back to safely cruising after dusk!

Try the following troubleshooting steps first! But if all else fails, and you need replacements, Golf Cart Stuff has the best lights on the market for Club Car, EZGO, and Yamaha golf cart models.

1. Blown Fuses

One of the most common causes of faulty golf cart lights is blown-out fuses. These fuses facilitate the transfer of electricity throughout the many systems your cart has, whether that’s the steering, radio, or AC. When the fuses to the headlights break, that flow of electricity can’t reach the headlights, preventing them from turning on.

Early Sign of Failing Fuse

Typically, cart owners will notice their headlights dim or flicker; this is a common symptom of a failing fuse. When you notice this, it’s time to service the fuses and replace them when necessary. Allowing them to degrade even further will only increase the likelihood of a total breakdown, leaving you without light when you may need it the most.

2. Malfunctioning Headlight Switch

The headlight switch is another common culprit in the realm of issues with golf cart headlights. If you have replaced the headlight assembly and fuses, and are still having issues, it may be time to inspect the golf cart's headlight switch.

The headlight switch provides the flow of electricity to the lights, so even if you install new headlights and fuses, if your switch is worn, broken, or otherwise malfunctioning, you will continue to have issues. While a fuse transfers the energy, the switch allows the electricity to travel; once it can no longer open the floodgates, no power goes to the bulbs.

3. Faulty Wiring

Another of the typical reasons why your cart’s lights don’t work can be due to faulty circuitry. This is a common mistake and easily corrected.

If you did the work yourself, simply refer back to the wiring guide(s) received with your headlight kit and verify your work, keeping in mind all other electrical components that may be installed on the golf cart.

Stop by this article next for our top tips on How to wire golf cart lights correctly.

Double-Check the Work

After any kind of electrical upgrade, if you notice anomalies in the power output of any of the systems, you'll want to revaluate the work you just did, or return it to the professional who did the work. Make sure it's right, so you don't get left in the dark!

J mansley,

Our comment to Patrick may be a good starting point for you as well.

Although you replaced your voltage reducer, it may still not be working correctly. There are a ton of voltage reducers available on the market, and like everything else in the world, the quality is all over the place.

For instance, there are a lot of voltage reducers sold on Amazon that are only rated for 16 volts but don’t make that clear in the description. As a result, customers end up hooking them up to 36 or 48 volts and the voltage reducer can’t handle that load.

Our first step would be to double check the output side of the reducer to ensure you are only putting out the required voltage for your specific lights.

Hopefully that helps!

Patrick,

We apologize for our delay in responding to your comment! Somehow we missed that when going through our sweep!

Typically if all the lights go out at the same time on the cart it is going to be one of two issues:

1. There is no power getting to the lights. Although you replaced all the fuses, double check that everything is making a good connection. Start with the batteries and work your way backward. It is not uncommon for a connection to come loose and lose power.
2. Your lights burned out. Usually, this is only a problem when you first install your golf cart lights. However, if something shorts out, it can cause a surge of power, to come through and damage the lights.

Hopefully that gives you some good direction moving forward!

all my lights horn 4 way flahers all out same time replaced voltage reducer still no go checked fuse all good can not figure it out

Patrick Martin - June 15, 2023

My lights stopped working suddenly. I replaced all fuses on the cart. Then replaced the headlight switch. Still no lights. I looked over the wiring but that all seems intact. The LED headlight shouldn’t be the culprit because the tail lights stopped working at the same time. I’m stumped.

George,

Thank you for reaching out! Yes, from what you are describing, there is more than likely either a faulty ground or faulty connection somewhere in the line. Typically, if you had a major issue such as a faulty voltage reducer or something like that, your lights would not work at all. Due to the fact that they work intermittently, there is probably a connection that is not secure. Let us know if you have any other questions! Thanks George!

George L Johnson - September 13, 2022

My Club Car lights work intermittently. I replaced the light switch, but the problem still exists. My guess is a faulty grounding in the circuit? The cart is in Florida and maybe there is corrosion in the wire connection?
