Installing golf cart lights correctly means matching the light kit to the cart, supplying the right voltage, protecting the circuit with a fuse, and routing the wiring where it cannot rub, overheat, or interfere with steering and suspension. Most aftermarket LED light kits run on 12V, so 36V and 48V electric carts often need a voltage reducer.
Confirm the cart and light-kit fitment
Start with the make, model, model year, and powertrain. A Club Car Precedent, EZGO TXT, EZGO RXV, Yamaha Drive2, and Evolution D5 can use different mounting points and wiring layouts. Model-specific kits usually fit cleaner than universal kits.
Check the required voltage
Read the light-kit label or instructions. If the kit requires 12V and the cart uses a 36V or 48V traction pack, use a properly sized DC-DC reducer. Do not connect a 12V kit directly across the full pack.
See our golf cart voltage reducer guide for 36V-to-12V and 48V-to-12V setups.
Disconnect power before wiring
Follow the vehicle service procedure before working on the electrical system. Remove the key, place the cart in the appropriate tow/run or service state where applicable, and disconnect battery power as the manufacturer directs.
Mount the headlights and taillights
Use the templates supplied with the kit if the body needs to be cut. Measure twice before drilling or cutting. Check the rear of each mounting area first so you do not drill into wiring, structure, or other components.
Route the harness safely
Keep wiring away from sharp edges, hot engine parts, steering shafts, suspension movement, and tire contact. Use grommets through panels and secure long runs with clips or ties. Leave enough slack where the body or steering moves.
Fuse the circuit
Install the fuse specified by the light-kit or reducer manufacturer. The fuse should protect the wire and accessory circuit. Do not replace a repeatedly blown fuse with a larger value until the cause of the fault is found.
Connect switches, brake lights and turn signals
Basic light kits may only include headlights and taillights. Street-use kits can add brake lights, turn signals, horn, and hazard functions. Follow the exact harness diagram because switch wiring and brake-switch connections vary between kits.

Test before reassembling everything
Reconnect power and test headlights, high/low beam if equipped, taillights, brake lights, turn signals, horn, and hazards. Turn the steering from lock to lock and check that no wire becomes tight.
Aim the headlights
After installation, aim the beams at a wall or flat surface so they illuminate the path without pointing into other drivers’ eyes. More brightness does not compensate for poor beam aim.
If the lights do not work after installation, use our golf cart light troubleshooting guide. For a 48V cart with 12V accessories, also see how to run 12V lights on a 48V golf cart.
Bottom line
A clean golf cart light installation uses the correct kit, correct supply voltage, proper fusing, protected wiring, secure mounting, and final beam adjustment. Treat model-specific wiring instructions as the source of truth rather than relying on wire color alone.
