Adding LEDs to anything makes it 5x better -- it's a scientific fact! But when you have LEDs, you've got wires and power supplies and all that stuff is kinda annoying. What if you could have LEDs that light up without any wires or soldering or battery packs? Sounds magical! That's what makes this 10 Wireless LED Kit so nifty. When paired with either our Small or Large Inductive Coil Kit, they use electromagnetic fields and inductive coupling to pass power through the air to light up lil LEDs soldered onto coils.
