40 Inch Marine Series Curved Double Row LED Light Bar – Pro Series 3.0. Unmatched Power. Proven Performance.
When you’re running after dark, only purpose-built marine lighting delivers the confidence and visibility you need. The 40-inch Marine Series Curved Double Row LED Light Bar – Pro Series 3.0 is engineered for serious marine applications, providing maximum coverage and long-range visibility while standing up to salt spray, humidity, vibration, and frequent washdowns.
For peak performance, our most popular configuration pairs the 5-watt high-output option with a Combo beam pattern, delivering powerful distance through the center spot optic while wide flood optics on the ends illuminate docks, channels, and surrounding water. The result is broad, balanced illumination ideal for night navigation, offshore runs, docking, and fishing—without sacrificing durability or reliability.

Frequently Asked Questions
Q: Should I choose the 3-watt or 5-watt version?
A: The 5-watt version is our most popular option, delivering significantly more brightness and reach for night navigation and offshore use. The 3-watt version is ideal for lower-power setups or close-range applications.
Q: What makes the Marine Series light bar different from standard off-road light bars?
A: The Marine Series is specifically engineered for harsh marine environments. It features corrosion-resistant hardware, a fully sealed housing, and a marine-rated waterproof design to withstand saltwater spray, humidity, vibration, and long-term exposure on the water.
Q: What beam patterns are available, and how do I choose the right one?
A: This light bar is available in Spot, Flood, and Combo beam patterns. Spot beams project light farther downrange for navigation and high-speed visibility, Flood beams provide wide coverage for close-range illumination, and Combo beams offer a balanced mix of both for all-around marine use.
Q: Is this light bar suitable for T-tops, hardtops, or overhead mounting?
A: Yes. The 40-inch Marine Series light bar is commonly mounted on T-tops, hardtops, radar arches, and other overhead structures. Its mounting system allows for precise adjustment to minimize glare and optimize beam direction.
Q: How waterproof is the Marine Series light bar?
A: The Marine Series carries an IP69K waterproof rating, meaning it’s fully sealed against dust and can withstand high-pressure water spray. It’s built to perform reliably in heavy rain, rough seas, washdowns, and wet marine conditions.
Q: Will this light bar cause glare on my bow or deck?
A: Proper mounting and aiming are key. We recommend temporarily powering the light during installation to fine-tune the angle and reduce or eliminate bow glare. Slide the light bar back enough on the hardtop to eliminate all bow glare. When aimed correctly, the light provides excellent visibility without unwanted reflection.
Q: What voltage systems is this light bar compatible with?
A: The Marine Series light bar is compatible with 10-30V DC systems, making it suitable for a wide range of boats and marine electrical setups.
Q: Does the light bar come with a wiring harness?
A: Yes. The Marine Series light bar includes a complete wiring harness with fuse, relay, and switch, allowing for straightforward installation right out of the box.
Q: Is this light bar energy efficient?
A: Absolutely. The Marine Series uses high-efficiency LEDs to deliver powerful output while keeping amp draw low — helping protect your battery system during extended use.
Q: Can this light bar be used for night fishing or docking?
A: Yes. The wide, consistent light output makes it ideal for night fishing, docking, loading gear, and general deck illumination, improving safety and visibility after dark.
Q: What warranty does this light bar include?
A: All of the products in our Pro Series 3.0 line is backed by Black Oak LED’s limited lifetime warranty, giving you long-term confidence in performance and durability.

United StatesBest Light Bar out there!
This is the best light I've ever bought. I do a lot of cat fishing at night on the Colorado River and this lights it up from bank to bank. I was skeptical until I used it . Best light on the market in my opinion.
United StatesBlown away!
I was blown away by the power of our Black Oak LED light. It is incredibly bright and lights up the entire work area. I utilize the black oak light for our ocean cleanup operations. Sometimes we stay out late collecting plastic and when we need to run home through mangrove channels our light bar helps us do so safely. It has benefited us by providing safety and peace of mind!
United StatesHelps a lot a night.
WOW THESE LIGHTS ARE AWESOME ! I USE THESE LIGHTS TO HELP NAVIGATE THE WATERS.
United StatesLooks factory

United StatesBeyond Satisfied
My first impression of my 40 Inch double row LED lights were simply WOW! My mechanic even commented how bright the lights were during the daylight. I chose Black Oak's marine product to best match my diamond plate trim on my F350 - a perfect match. I heavily researched the best LED'S on the market and concluded Black Oak manufactures a superior product. This company has exceeded my expectations. Do your own homework - you'll end up at Black Oak's website. And, if customer support is important to you, this company is second to none. My particular LED setup was custom made to order. I happen to live in a hollow, deep in rural America where it's pitch black. Black Oak noticed I requested flood lights on the marine light bar which is uncommon and contacted me immediately to discuss my application. When I gave them the details of my situation - backing a large truck in a tight area with ditches on both sides of a narrow driveway, they immediately understood. I received a production date and they delivered on-time. In short, just buy from this company. They make the best products, have the best value and offer incredible ongoing support regardless of your application.
