How Underwater Green Lights Work for Fishing

Many people love to fish. Fishing has been a favorite pastime for men for many years. People fish for many reasons. People like to fish because it’s relaxing and makes for good leisurely activity on the weekend. In the past and even in this modern-day, people fish so that they have food to eat. Also nowadays, there’s people that try to catch the largest or heaviest fish to win contests. Regardless of the reason, people love to fish. Fishing can be done at any time of the day but there’s some that like to fish at night. Fishing at night can be difficult because you can’t see the fish and the fish can’t see your bait. In the past, people who went fishing at night hung lanterns on the sides of their boat to attract fish. However, the lanterns attracted a lot of bugs but not as many fish. Luckily nowadays, people can use something called submergible green lights to help attract the fish.

How it works?

Green lights work by helping the fish see. Fish don’t see well at night so fish rely on smell, sound and vibrations to find food. The green lights will attract the fish to your bait which will help you catch more fish at night. The green lights work by by being submerged in the water and because the light is so bright in the water, the green lights will start to attract plankton. The plankton are attracted to the light for reproduction which attracts smaller fish.

The smaller fish will come to eat the plankton and be attracted to your bait. When enough smaller fish are around, larger fish that people like for trophy will start to gather. The larger fish are attracted by the smaller fish and the brightness of the green lights. All these fish here will give plenty of variety of fish to catch and increases your chances of having a fish on your line.

Green lights work the best because all members of the food chain such as; plankton, smaller fish and larger fish are sensitive to the color green. These animals can tell when something is different in the water. The green light signals that either food is there or a predator is there.

The plankton will be naturally drawn to the bright light then the fish will smell the food and also be naturally drawn to the green light. Fish living in these environments have color receptors in their eyes and can tell the contrast between the normal watercolor and the green lights.

How green lights maintain its color

The green light maintains its green color while being submerged in the water making it easier for plankton and fish to see the light. The green light makes it so that the specific area of the water is illuminated making it easier for fish to find food. Having the green light is also beneficial for fishing because you’ll be able to see the types of fish in the water. Fishing at night is fun but difficult because you can’t see the fish in the water. It’s always a mystery at night as to what is in the water to catch but with the green lights, you’ll know exactly when to put your fishing pole in the water.

Having the green light illuminate the water will help you see if the smaller fish are worth it or if you’d rather wait for larger and more prize-worthy fish. Without green lights, you might sit for hours with no fish biting at all because the fish can’t see you. Also without green lights, you might keep getting the same small fish biting that you’ve been putting back into the water many times but it’s too dark to tell.


Green lights help attract fish to your dock by helping the fish to see their prey. The green lights attract plankton which attracts smaller fish then attracts larger fish. The plankton and fish are sensitive to the color green and have color receptors in their eyes. These animals can tell the contrast between the color of their normal water and the green lights.

The green lights tell the fish that either there is food by the light or there’s a predator by the light. Having the water illuminated will also help you be more productive when fishing at night because you can see what’s in the water. The green lights help you know when to put your fishing pole in the water.
