A Rainbow Shower Head like this one works by powering LED lights using the natural power of the water flow. In other words, you will not need any special batteries or electricity to operate them. You simply twist the shower head onto any standard sized shower pipe where the old shower head was.

This Rainbow Shower Head in particular has plenty of good customer reviews you can read through to help you out. Many other versions are offered aside from just the one shown here.

As far as this exact Rainbow Shower Head goes, I mentioned that most of the feedback comments are positive, there are a few negative ones you will see that mention that it is made with plastic parts that are not all that durable. You can find stronger Rainbow Shower Heads that might cost a bit more money, but perhaps worth it in the long run.
