Most golf carts do not come with lights because their primary use is for the day on golf courses. A lot of people have begun using golf carts to get around large areas at work and at homes with large yards. If you use your golf cart at night for transportation, you should install lights to help you see where you are driving. You do not need to hire a mechanic to install lights on your golf cart. You can install lights on your cart in an afternoon.
Difficulty: Moderately Challenging
Disconnect the chassis black wire from the negative battery terminal on your golf cart. Then, mount your lights on either the front bumper or top of your golf cart if your cart has a roll bar. If it does not have a roll bar, then clamping the lights to the front bumper is the next best place to install the lights.
Mount the toggle switch for the lights on the driver's side of the dash. Drill a 1/2 inch hole in the dash to thread the mounting screw for the light switch.
Connect one of the leads of the inline fuse holders to the positive terminal of the battery with a ring terminal. Use a "butt" connector to connect the un-attached lead of the in-line fuse holder to the middle terminal of the toggle switch with a female spade terminal.
Use 16-gauge wire and connect the second terminal of the toggle switch to the headlights' positive connection with a butt connector.
Cover all of the connections with electrical tape and then secure the wiring to the body of the golf cart with nylon wire ties.
Set the toggle switch in the mounting hole previously drilled. Then, re-connect the negative battery terminal. Test the light by turning the light switch to the "on" or "up" position and your lights are now setup.
