This amazing cost saving device eliminates the guesswork of determining the correct tyre pressure for your vehicle. Proper inflation of your tyres helps reduce the risk of poor handling, blowouts and accidents while improving fuel economy and tyre life. 
Air Alert is a reactive warning, once installed the device will blink when a loss of PSI occurs (4PSI for cars & 8 PSI for commercial vehicles), so just walking up to the vehicle will highlight a under inflated tyre.
Air Alert is ideal for commercial vehicles and trailers, when a tyre valve is not visible the devices LED will blink so bright, the LED will show on surrounding surface areas, making inner axled tyres easily checked.
