Underwater Boat Lights: What You Need to Know

Owning a boat allows you to use it how you want, whenever you want. But without the right boat lights, you risk navigating with limited visibility. Using multiple types of lights in the right areas of your boat can help you safely navigate in situations where visibility is limited.

But lights on boats are no longer solely about visibility. They help provide additional safety when getting on or off, set your boat apart, giving it a unique look and appeal, and in the case of underwater boat lights, can aid in fishing at night.

  • LED navigation lights
  • Boat navigation lights
  • Underwater lights
  • Flood & deck lights
  • LED strips
  • Recessed

  • Reading lights

What are Underwater Boat Lights?

Underwater boat lights, commonly referred to as underwater marine LED lights, are either surface or hull-mounted lights. They are designed to provide light from just underneath the surface of the water when a boat is docked or in motion.

Underwater boat lights are designed and manufactured using advanced marine lighting technology and are created for marine use. They are durable and easy to maintain. When using them on your boat, they require installment.

How do Underwater Boat Lights Work?

Underwater boat lights use an external power source (commonly a boat battery) to project light. The light travels through the water from its location attached to the vessel. Depending on the color, brightness, location, and quality of the light, how far and how bright they shine varies. 

The Benefits of Using Underwater Boat Lights

The benefits you can gain from adding LED underwater boat lights depend on your intentions and needs. Underwater boat lights are usually fitted to a boat or yacht for one or several of the following reasons:

  • Offer additional lighting for safety
  • Provide a unique look to a vessel
  • Improve visibility to help with navigating backwards or seeing behind the boat
  • To attract fish while angling at night

Fishing with LED Underwater Boat Lights at Night

Anglers use LED underwater boat lights during the evening to attract fish. Lights with a strobe function and combinations of colors (white, blue, green) can appeal to zooplanktons and shrimp, which will attract predators. 

If you are using LED underwater boat lights for fishing, anchor your boat prior to turning on your lights and come to a complete stop. If in motion, fish will have a difficult time finding your boat.

Using at least two lights spread apart is recommended to increase the amount of water your lights will cover.
