The faucet experience is so boring. Clear water, always the clear water. What if you could have a party in your faucet? Turn the water on, and the running water activates the LED, making the water look bright blue. You could also use it as an additional light source for doing sexy dishes. Each faucet light set includes 3 button cell batteries, a wire screen, 2 universal adapters. All of that for about $14.97. Not too bad for something that'll add some pizazz to the bathroom, letting you wash in the same blue colored water that swirls around the toilet bowl. Ah, refreshing!
