Sometimes when I go for a quick shower in the morning I don’t even see if the water is hot or cold. This reminds me of an incident, once it was winter and I ended up having a cold shower. Oh boy! That was really sick. Now, here’s something that would have helped me that day, a LED Shower Light.
The LED Shower Light has a unique feature. It not only lights up but also lets you know if the water is cold or hot. When you turn the shower on, the LED Shower Light lights up. If the water is cold it glows blue. When the water is hot and reaches above 32*C, it turns red. It doesn’t require any batteries to function; it’s powered by an internal turbine. The LED Shower Light is priced at around $40. You can get hold of one at Thinkgeek.
