Package Contents LED shower head FAQ - Frequently Asked Questions What color LED's does this product contain? Red, green and blue. If I use this shower head, does that mean I do not need to turn on my bathroom light? Usually the light provided by the LED shower head is enough to take care of all of your "business" in the shower. How is the LED powered? The water current flowing through the shower head powers the LED.
