Underwater LED Lights for Boats to Light Up the Night

Underwater LED Lights for Boats to Light Up the Night

What do you do when the sun goes down? If you're out on the water and heading home, well, you're missing out.

Personally, thanks to installing some of the best underwater LED lights for boats, I can stay out all night. I can go fishing, jump in the water or simply keep cruising to my heart's content.

Adding LED lights to your craft (just like adding them to your dock) is an absolute must for serious summer boaters. Not only do they look cool, but they're affordable, environmentally friendly and only require a little bit of power to provide long-lasting shine.

Let me tell you a bit more about these lights, what features to look for and how you can buy them for your boat today.

Common Uses for Underwater LED Lights

You might want to consider underwater LED lights for your boat for three main reasons: fishing, ambiance and safety. Let's discuss a bit about each.


Using underwater LED lights to fish at night is a great way to attract fish for serious anglers. Green lights, especially, reach further distances and do an excellent job to attract zooplankton and other fish food (and, therefore, more fish!).

Whether you fish for fun or for sport, a green LED fishing light might just be what stands between you and the catch of the day when you drop anchor, line and chain and cast a line.


Make your boat look super cool with the perfect finishing touch by installing underwater LED lights. In the evening, they add a nice ambient glow and show off your boat's best angles.

The best part about LED lights is that they typically come with multiple color options. If you're not fishing that night, you don't have to go green. Instead, you could change it to blue or red. Either look particularly cool in the water, but the best part is you can choose a color to match your mood!

It's that easy. Honestly, I can't tell you how easy it was to install some simple drain plug lights, and how many people would often turn their head, exclaim how cool it looked, or asked how to get them onto their boat. It was eye-catching, and it also made night swimming a breeze.

Nighttime Safety

Speaking of night swimming, another important use for underwater LED lights is that they help improve nighttime boating safety. Especially out in busy lakes and ocean coves, you want to ensure you remain extra visible (whether you need help or want to avoid trouble).

Installing underwater lights creates a dispersed glow like a beacon, making other boaters to take note of your location and for your own party to get home safely and worry-free after a night of fun.

Mounting Options For Underwater LED Lights

Before I introduce you to some of the best underwater LED light options on the market, it's important to consider where you can install them so you have a better idea of what type is best for you and your boat.

Typically, the most common types are surface mount LEDs, drain plug LEDs and thru-hull LEDs.

  • Surface Mount: Great for smaller boats, these lights only require you to drill small holes. You can install them on the transom or on the hull, but your overall light will be limited due to their size.
  • Drain Plug: Screwing directly into your boat's drain plug, this type of underwater LED lights are the most impressive-looking. Plus, they take especially little effort to install.
  • Thru-hull: It's right there in the name! These lights are installed through the hull and are typically used when you need some serious underwater glow. Transom-mounted and involving a bit more in terms of installation, these are the kinds you need for fishing.

The first two options, surface mounts and drain plugs, are the easiest to execute, but are typically reserved for those who simply want some ambient lighting and maybe the occasional nighttime fishing. 

But if you take fishing seriously, consider the thru-hull option that offers a broader beamwidth. The beam width, which is basically the scope of the light, is essentially how far your underwater glow will go.

When you install your light through the hull, you gain access to a much wider beamwidth, like a target, to attract more fish to your surrounding area. It's like casting a fishing net with a beam of light!

Underwater LED Lights for Boats to Light Up the Night

Now that we've talked a bit more about how they work, which LED lights should you throw in your shopping cart? Divided into three sections - fishing lights, drain plugs and surface-mount lights - these are my recommendations for the best option to light up your life.
