YALOK 4PCS Glow-in-Dark Tire Valve Stem Caps, Air Covers, Blue | Standard valve fit, cars/SUVs/trucks/bikes, ABS insert, rubber seal, hand screw-on, light-charged, exterior accessories

They are nice. But they do not GLOW

Two of them have fallen apart already. I have left them all in the sun for 2 consecutive days of 90 plus degree sunlight. None of them exhibit any signs of illumination yet.

Colored valve stem caps, not much to say..

These are junk. They never worked right out of the box. Not once did they glow at nighttime.

I had already bought cobalt blue metal stem covers at auto zone BUT, when I saw these (surfing for accessories 4 my "new purchase) I actually said "wow... I want those!".. I was really looking forward to the color and glow at night. They emit NO color/glow sitting there so thought maybe they needed the "wheels spinning " to generate the glow (since it wasn't doing anymore sitting there!) So I even had a friend watch/video me drive it up/down street so I could see it. BUT.... NOTHING! NOT even a miniscule hint of a glow! Granted the cost was ridiculously inexpensive; BUT, it's the principle. Judging by the other reviews (which I didn't scroll much prior to purchase) I didn't randomly get "the Duds" and the lack of any color is not an isolated case... frustrating...

After years of using these they do fade to white. Very easy to use and they looked cool at first.

These caps glow brightly in the dark, making it easy to locate your tires at night or in low-light conditions. Beyond their glowing feature, these caps add a stylish touch to my car. They enhance the overall look of the vehicle and make it stand out, especially in the dark. These valve caps would make a fun and practical gift for any car enthusiast or someone who enjoys unique automotive accessories.

the valve stem caps visually appealing and cute for about three days, though the color fades within a couple of weeks. The build quality receives mixed feedback, with some finding them sturdy while others say they don't fit well. Moreover, the functionality and value for money are criticized, with customers reporting that they don't work as advertised and consider them a waste of money. Additionally, the glow feature receives negative feedback, with customers noting that the caps don't light up at night and stop glowing after 30 minutes.

No glow in dark

لايضيء في الليل ولايرى بوضوح في النهار لا انصح بشرائه

No brillan en la noche, no son flourescentes, son simplemente tapones color azul para las ruedas, no tienen ningun chiste.

ولا بتنور ولا بتاع خالص.. هي بس لطيفة كسدادة بلف مش اكتر.. وسعرها معقول بالنسبة لخامتها

Good
