If you hate waiting for the shower to heat up and checking on it every few seconds, you might like to get the LED Shower Light. It turns from blue to red when the shower water heats up.
Features

- No batteries needed. It’s powered by an internal turbine.
- It has a Flow Regulator that limits the maximum water flow to 2.5 gallons per minute at 80 psi
- Approximately 4″ in diameter
