12PCS Glow-in-Dark Tire Valve Stem Caps, Air Covers, Blue | 0.47 Inch diameter, passenger cars/SUVs/trucks/bikes, ABS/phosphor body, hand screw-on, light-charged, exterior accessories

I would give them ONE STAR! I should have listened to the other reviews. THEY DO NOT WORK! ‘Charged ‘ them in the sun like directions said and THEY DONT GLOW. I will be returning I want my money back idc if they were cheap or not

I love how it was easy to install as well when im driving at night you can see my tires highlighted blue.

Bought these to give a little fun glow to my BMW i3 for nighttime rides. These stem covers are worthless. Cheaply made, and despite charging all day in direct UV light, outside in the sun, all day, they did not glow. Now even a little bit. Disappointed in the product, even if they were cheap, at least they should glow a little bit and not fall apart while screwing them onto the valve stem. Not worth even returning, just going to chuck them in the garbage.

The Luminous Tire Valve Stem Caps are such a fun and practical addition to my car! These 12PC caps not only add a unique glow to my vehicle but also serve as a great safety feature, making my car more visible at night. The glow is bright and lasts a good while after dark, which is a nice touch! The quality is excellent—the caps are durable, easy to install, and stay securely in place. They're made from high-quality materials, so I’m confident they’ll hold up over time. I’ve gotten so many compliments on how they look! If you want to personalize your car and add a little extra flair, these valve stem caps are the way to go. Highly recommend them!

I haven’t put them on my truck yet but it seems like the glow is not as bright as you would think it to be. They’re very bright after I activated it under my nail uv light but it seems as if they dim fast. I need air caps bc magically they keep disappearing off my tires so either way I’m keeping them. It is still day light out so, when I put them on, I’ll do an update on the brightness of the glow at night.

The tie came quick and was very vibrant. I have only had the item for roughly 3 weeks and installed them the day I got them. They never really showed up at night and they have already sun faded in just 3 weeks, see pictures. I have removed them and purchased different ones. In the last picture you can see the new vs used ones.

Good

this tire valve cap is waste of money. It 100% does not illuminate at night. The powers to be at Amazon need to remove this off of the site.

Not as per advertised. Not glowing. Not recommended to anyone.

Just average quality. Look good.

Won’t buy doesn’t work

They work as a tire valve but aren't luminous in the slightest

The “Luminous car tires caps are not Luminous at all! …disappointed! I bought the red ones and they are not glowing in the dark, don’t know about the other colours
