The Indiglo night-light, like that featured in Timex brand watches, and other Timex products, uses a space age lighting material that is totally cool to the touch, so there is no danger of burned fingers. And, there are no bulbs to replace. The Indiglo night-light measures a slim 1/4 inch, making it difficult for children to pry it away from the wall, and reducing the risk of electrical shocks. Saves Electricity: The Indiglo night-light, operating 24 hours a day - seven days a week, uses just pennies worth of electricity per year! It more than pays for itself with the money you'll save in electricity. And by saving electricity, you're helping to conserve our natural resources! Uniform Glow: The Indiglo night-light provides a bright and uniform blue-green light across its entire surface and is easy on the eyes. Contemporary Design: The Indiglo night-light has a contemporary design that blends with any dcor. It's perfect for bedrooms, hallways, living rooms and more. You're Never in the Dark: The Indiglo night-light packs easily for trips away from home. Its familiar glow will make unfamiliar hotel rooms safer to move around in at night.
