Many anglers use “black lights” and fluorescent line when night fishing. Under the illumination of the black light, fluorescent line glows like neon and makes subtle strikes easy to detect. I wish some of the sturgeon guys would speak up about what line they use.. because I can see it glowing from quite a distance at night.
For myself when I’m trolling for or anchored for walleye or casting for Musky I just use a 12 volt spot light , like you would use for shining deer pointed in the direction I am fishing … I personally dislike jigging in anything less than daylight or with out a clip-on led lights on my hat, and I almost always have Stren High Vis on so I can actually watch it realitively well. The other thing I also do at night is use a heavier jig when jiggin so that I can feel more than see that I am keeping in touch with the bottom.
But as with almost any other subject Googling it also give you a bunch of ideas.
