Review on 🚲 BAIONE Universal Tire Pressure Indicator Valve Stem Caps for Motorcycles SUVs Bike Bicycle Trucks - Dust Stem Covers with Car Tire Pressure Monitor Valve Stem Cap (B) by Billy Reeves

EDIT: This caused a slow leak in one of my tires. The complete opposite of what they are intended for. Dissatisfied. Return window exceeded. Cannot send back. ORIGINAL VIEW: They appear green when the tire is properly inflated. Now, when the weather temps drop and the tire gauge lights up on the dash, I can visually tell which tire needs attention. But again, they're so cool, I hope nobody stole them.
