Definitions

  • the present invention relates generally to a flashlight and pressure gauge kit.
  • the popularity of tactical flashlights has increased in recent times.
  • the flashlights provide good illumination in a small package because of the use of LED lighting technology.
  • the LED technology permits the implementation of strobe and SOS functions that are attractive to users.
  • the flashlights are typically made from aluminum, which makes the flashlights sturdy, and which add weight that give the flashlights a feeling of reliability.
  • the weight is attractive to tactical uses of the flashlight, which includes a flashlight head which is strategically designed to allow a user to strike an opponent.
  • TPMS tire pressure monitoring systems
  • TPMS systems There are, however, accuracy and reliability issues with TPMS systems. In particular, many TPMS systems simply warn a user if a tire is low, and do not inform the user of the pressure of the tire. Depending on the threshold pressure value used for the warning light, a driver that relies on TPMS may drive thousands of miles on tires with suboptimal pressure, before the pressure reaches the threshold warning level. This can cost the driver in both reduced gas mileage and increased tire wear. Further, TPMS systems typically use valve stem transponders that have a finite battery life of 3-5 years. Replacement of each TPMS unit can cost from US $50-$100, meaning that a set of 4 units for a typical car can cost from US $200-$400.
