Here’s a great Firefly LightUp Timer toothbrush made by Dr. Fresh in 2011. Unlike some if their later versions, these toothbrushes have specifically sculpted characters as their handles. When you push the button on the ’S’ symbol, red lights flash throughout the handle all the way up to the actual brush tip itself. The flashing lasts for one minute which is designed to be the amount of time a child is to brush each row of teeth. Other characters available included Green Lantern (Hal Jordan), and Batman.
