Product Description
SET of TWO (2) CAPS. The LED Tire Alert Valve Cap is a small device that will start blinking if the tire pressure falls 4 psi below the correct pressure. It is an active warning, which will be seen by the driver as she/he approaches the vehicle. The Valve Cap is designed to replace the regular dust cap on a tire. Therefore it will fit most passenger cars, pick up trucks, large trucks, tractor trailers, fork lifts, motorcycles, bicycles, lawn mowers or wheel barrels. The Valve Cap is so small (approx. 1" x ½ ) and light (only 0.3 oz) that it will have no impact on the wheel balancing or the appearance of the vehicle.
Features of the LED Tire Alert Valve Cap:
Durable design
The Cap is designed to withstand even the toughest conditions. The body is made of nickel-plated aluminum and the clear cap is made of clear Polycarbonate. It has no moving parts except a membrane, which will flex slightly if the tire pressure drops. The Valve Cap is entirely sealed and therefore no moisture, dust or dirt can enter into it.
Self-Calibrating
The Valve Cap is self-calibrating. When the cap is mounted on the valve stem the first time, it will memorize that tire pressure. The cap is calibrated for life and does not need to, and cannot be, updated later. The Cap can be calibrated to any tire pressure between 20 and 110 psi. Since most car manufacturers recommend having different tire pressures for your front tires vs. your rear tires, the ability to self-calibrate gives you the flexibility to calibrate each valve cap to the appropriate pressure
Easy to install
Since the Valve Cap is self-calibrating no further calibration needs to be done by the installer. The Valve Cap is also 100% self-contained with onboard batteries. The LED Tire Alert Valve Cap can be installed in just a few seconds more than it takes to check the tire pressure and it does not need to be done by a trained technician.

 These Caps Work Well - But For Daily Drivers, 2008-10-27
I have used these caps on my car for about 2 years with good results. My Jaguar XK8 has stock 18" low-aspect ratio tires with thin sidewalls. One morning, my right rear tire picked up a nail and leaked down to about 18 psi, which wasn't quite flat yet, but enough to ruin the sidewall ($300 tire replacement). After that expensive lesson, I decided to use these metal valve sensors. After two years, three of the sensors still work. The one sensor that is out is because the car sat with a low tire for an extended weekend before I noticed the tire was low. That's why these are best for cars that are used daily. On my old minivan, I tried using the plastic tire sensors with the multi-colored pop-ups, but after a year they caused flat tires by leaking! I think these solid chrome metal sensors are your best (and safest) bet!

 Frozen in place, 2008-08-28
After about a year tried to remove them to add air to tires. Absolutely locked in place!! Won't budge--I plan to use a hacksaw to remove them, FOREVER!

Waste of money, 2008-08-15
Bought a set to monitor spare tire in trunk. Unless you open the trunk every day the battery will go flat if the pressure drops. Waste of money

 Freeze onto valve stems, 2008-07-25
These are great for warning of low pressure, but mine got frozen onto the valve stems after about 2 years. Required vice grips and damage to valve stem to remove them. If you use them, put some grease (maybe plumber's grease?) on them before attaching.

They Don't WORK, 2008-05-14
I purchased a set and installed as per the instructions. After about a month I decided to use a tire pressure gauge to see my tire pressure. I was down over 8 pounds per tire. The valve stem caps never lit to indicate low pressure.
