Fishing Dock Lights for Redfish: 6 Best Picks for Night Anglers

By Miles Sinclair

Updated November 2026

Fishing dock lights for redfish are one of the simpler ways to fish at night from a dock, pier or seawall. A submersible light draws baitfish and shrimp toward the water column, and redfish often follow the bait within casting range. The challenge is that dock lights vary a lot in brightness, power source, cable length and build quality, and a light that works well over a freshwater lake may be a poor match for a saltwater flats dock. The picks below were chosen by comparing manufacturer specifications, brand reputation and the patterns owners commonly describe, with attention to waterproofing, power options and cord length. None of these lights were personally tested, so check the listing details before buying.

Our Top Picks

Before comparing individual lights, it helps to understand what matters most for redfish. Redfish typically feed on shrimp, crabs and small baitfish around docks and pilings, and green light tends to be favored by anglers because it carries well through water and draws bait. Look for an IP68 or similar rating for submersion, a cord long enough to reach your water depth, and a power option that matches where you will plug in. Our selection emphasized these points.

Buying Guide

Waterproof Rating

Look for an IP68 or IP69K rating on the listing. These ratings indicate protection against long-term submersion and high-pressure water. Saltwater is harsh on electronics, so a clear rating matters more at the coast than on a freshwater lake.

Good picks for this: Ultra-Bright Underwater Fishing Light and Goldlife 400W Green Underwater Fishing Light

Power Source

Decide whether you will plug into a household outlet, use a 12V battery, or both. Dual 110V and 12V lights give you options, while 110V-only lights need a nearby outlet and a GFCI-protected circuit.

Cable Length

Measure the distance from your outlet to the water and add the depth you want to submerge the light. Pilings and piers often need 30 feet or more. Remember that a longer cable adds weight and can tangle, so coil it neatly.

Brightness and Output

Listed lumens and wattage give a rough sense of how far the light reaches. Higher output can attract bait across a wider area, but it also draws more power. Smaller lights work well for a single dock post or shallow water.

Light Color

Green light is commonly used for attracting baitfish and shrimp underwater, and most lights in this list use it. Check that the listing specifies green rather than a mix of colors if you want consistent attraction.

Safety and Electrical Protection

Water and electricity are a dangerous combination. Use a GFCI-protected outlet or a plug with built-in GFCI protection, keep connections above the waterline, and never run cords across wet surfaces. If you are unsure about wiring or outlet safety, consult a licensed electrician.

Mounting and Durability

Most dock lights hang from a rope, clamp or bracket. Check that the light can be secured so it does not swing into pilings, and rinse it with fresh water after saltwater trips to extend its life. Clean connections and inspect cords for cracks regularly.

FAQ

Do redfish really respond to dock lights?

Redfish feed on shrimp, crabs and baitfish, and lights can concentrate that prey near docks and pilings. Many anglers report that redfish show up within casting range of a lit dock, but results vary with tide, water clarity and season. Fishing at a moving tide often improves your odds.

What color light works best for redfish?

Green is the most common choice in the lights listed here because it is widely marketed for attracting baitfish. Blue and white lights are also used by some anglers. Try what the local bait is showing you.

How deep should I submerge the light?

A common approach is to place the light a few feet below the surface, which keeps it visible to baitfish without hanging in the mud. Adjust based on water depth and where you see bait gathering.

Can I use a dock light in freshwater?

Many lights in this list are listed for both fresh and salt water. Confirm the waterproof rating on each listing, and rinse the light after saltwater use to protect it.

Is a GFCI outlet necessary?

A GFCI outlet cuts power quickly if it detects a current leak, which is important near water. Using a GFCI-protected plug or outlet is strongly recommended. For wiring questions, consult a licensed electrician.

How long should my extension cord be?

Measure from your outlet to the water and add the depth you want the light to reach. Use a cord rated for outdoor and wet use, and avoid running cords through standing water.

Conclusion

For most anglers, the NS Green Underwater Fishing Light offers the strongest listed output and dual power, making it a good overall choice. Anglers who move between dock and boat may prefer the Ultra-Bright Underwater Fishing Light for its 110V and 12V flexibility. Those fishing long piers should consider the Goldlife 400W model for its 100-foot cable and GFCI plug. Beginners and budget-minded buyers will find the Super Bright 12W light a practical starting point. Match the light to your power source, cable length and water depth, and always prioritize electrical safety at the dock.
