Luminous Tire Valve Stem Caps for Car, 12PCS Fluorescent Glow in The Dark Air Caps Cover, Illuminated Corrosion Resistant Tire Pressure Caps, Universal for Car, Truck, SUV, Motorcycles, Bike (Blue)

Just didn’t work. Left these out in sun, even tried another set with a black light. Waste of $ for me. It takes me a lot to write a one-star, but when the product doesn’t do what it’s supposed to, it leaves little room to be be complimentary. Fortunately, these are not expensive, so it was not a significant loss.

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!

A zero would be my review for this product if possible. The product does glow in the dark for a few minutes, but not enough to add some bling to your vehicle. Amazon does offer a battery powered option for just a for dollars more and the product lights up when my vehicles are in motion. The product comes with batteries installed. Here is the link to what I purchased: https://www.amazon.com/dp/B08998Z44C?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1.

For all ppl confused on how glow in the dark works you have to activate them so if there not glowing out then under a black light for 10 minutes and they will even glow in the light they will even glow if you cover them just a little with your hand mine are GREAT

I got 8 in one pack and only 2 it on my car doesn’t glow in the dark

Doesn't light up as well as I would have hoped for

Company does a little bait and switch on you With the immediate pictures. The product though isn't bad at all for the price. Took about a day in direct sun to get them to glow but now that they do I'm super impressed. For roughly 6 dollars you cant go wrong.

I bought these caps 2 days ago and extremely disappointed. I put them on my truck the first day and by night expected to see glowing. Absolutely nothing! I figured maybe they didn't get enough sunlight so I took them off this morning and lut them in the bed if my truck in direct sunlight for 8 hours. Put them back on the truck this evening. Nothing! I would think even a faint glow would be a good sign but when I say nothing. I mean nothing.
