“Spinners are classic “low riders”. They sit on or in the film and can be very difficult if not impossible to see; both natural and imitation.

That is easily overcome with the use of a fluorescent indicator; thus the “Lighthouse” moniker.

Bright fluorescent yellow is the color for spinners that fall dusk-to-dark. One can see fluorescent yellow longer in the dark than fluorescent white.”
