Slabs, night fishing

Second time ever tried night fishing for crappie. Think I finally figured it out. Did'nt use any light except for the green fluorescent. Adjusted the heighth of the light for the depth of fish. Caught 28 fish, 7 nice slabs walleye & channel cat all on suspended minnows.

Is that green flourescent available anywhere? Or is it a special water-proff fishing light? Where to get one?

Bought it at walmart. Have'nt seen them anywhere else. Good luck. Sure works for me.
