Checking tire pressure is difficult enough, so it’s about time someone simplified the chore. The Talking Tire Pressure Gauge can be used in the day or night with its LED. Solar-powered, it has a circular radial light and back lit plate with digital display. Good for cars, trucks, and almost all things cycled, the red gauge includes a depth ruler and auto-shut down. Made of ABS with sheet metal, it requires 2 CR2032 batteries and comes at a price of only $9.99.
