KIFIDAN Luminous Valve Wheel Cover Tire Valve Stem for Car, Air Cap Fluorescent, Illuminated Car Wheel Stem Cover for Car, SUV, Motorcycle, Truck, Electric Vehicle (8 Pack) (Red)

I love it so easy to tell if the tires need air.

Installed 8 of these on 2 vehicles. No leaks and the accuracy on 7 of the 8 was acceptable. One of the eight always shows low pressure, so I'll be replacing it. You DO need to pay attention to which caps you order as they come in different/multiple pressure ratings.MISC: I notice that one of the reviews posted stated that theirs were not labled. They are labled but it is very difficult to see. Mine are labled in BAR pressure. If you are out there kneeling down on the ground in sunlight you probably won't be able to read the pressure rating label. It's on the very end of the clear plastic cap. Satisfied so far. I'm curious to see how they perform this winter: Leaks, accuracy, etc. We'll see.

This product was awesome will buy in all colors next time

poor

Great product if they all worked but 3 out of the 8 would not register the air in the tire. Changed the ones that didn't work with one in the set that did and it was fine. Thought I'd have a spare set but instead I threw the bad ones away!

It Works but not 100%.

Of the eight received, I install the first four on my 2008 Nissan Sentra. Within a half an hour one broke, When installed showed yellow. Went and adjusted air in the tires. Added, another to the front passenger tire. Now they are all green, Like, they should be. Now, I only have three spares. I'm short one. So, far they haven't made it 90 days. Let see how long the rest will do.

Bought them put them on tire and they leak
