I always put some type of reflextive material on a plug if I can.
Krystal flash on a tail hook, glitter on a plug. When any light hits it, will get some type of reflection (bright), i would think. Kinda like a chrome metal lure.
In the dark, moon light or other area lighting in certain areas I would think would impart some type of light reflectiveness.
Always trying to increase the odds of getting a strike.
