Headlights parts for golf carts are essential for safe nighttime driving. They come in a variety of styles and sizes to fit different golf cart models. Most headlights are powered by 12-volt batteries, but some may require a higher voltage. Halogen bulbs are the most common type of bulb used in golf cart headlights, but LED bulbs are becoming increasingly popular due to their long life and energy efficiency. Installation of headlights is relatively easy and can be done with basic tools and a few simple steps.
