Marker lights are an essential component of a boat trailer that provide additional visibility to the trailer while it is being towed. They are typically located on the sides and rear of the trailer and are designed to indicate the width and length of the trailer to other drivers on the road.
The marker lights on a boat trailer can be either incandescent or LED. LED lights are more energy-efficient and have a longer lifespan than incandescent lights, making them a popular choice among boat owners. They are also brighter and more visible than incandescent lights, which can be especially helpful when towing a trailer at night.
The number and placement of marker lights on a boat trailer depend on the size and type of the trailer. According to US regulations, trailers less than 6 feet long do not require front side marker lights or front side marker reflectors. However, trailers over 80 inches wide must have additional lighting for better definition and determination of their shape at night.
When installing marker lights on a boat trailer, it is important to follow the manufacturer’s instructions carefully. The lights should be securely mounted and wired to the trailer’s electrical system using a wire harness. It is also important to test the lights before hitting the road to ensure that they are working properly.
