Why buy these when you can make em from a dead battery and pennies worth of parts? I think the clear epoxy and glow powder if you use it are the most expensive parts. Posting this here since i cant find the post related to paklites. 2 white leds and 100 ohm resistor works well. Want glow? Mix epoxy and quickly stir in glow powder . you have about 5 minutes to apply it.
