IllumiSink Light-Up Faucet Attachment
Waking up and trying to get yourself some water in the dark is less likely to lead to a refreshing drink, and far more likely to give you a mouthful of lava. That's why the IllumiSink gives your faucet the power of visual communication. This attachment integrates a temperature sensor and three colored LEDs to let you know whether the water is going to melt your flesh or not. It's totally powered by the running water, and it's the easiest way to know what you're pouring into your glass in the middle of the night. The IllumiSink can be had for just $10.99.
