12PCS Fluorescent Car Tire Valve Stem Caps, Auto Corrosion Resistant Wheel Valve Cover, Luminous Illuminated Glow in The Dark, Car Decor Accessories Universal for SUV, Trucks, Car (Yellow1)

These are very pretty and nice when its dark out but they don't light up as much as I though they would. They also stop working once the sun shines on them for like a day. Still would buy them again though.

I drive all day long for work so multiple times I had the caps in the sun for numerous hours but none of them glowed..... and I mean none at all. I was excited to see the effect they had but was really disappointed instead.

Very bright

They lit up well in the house when I got them. They don't work at all on the wheels.

These caps definitely glow in the dark - but it has to be dark. I wouldn't buy if you live in heavily light-polluted areas like NYC.

The only way to use these is to keep them off your car then charge them with a flashlight for like 2 mins of glow, bec they have very little zink sulfide (the glow on the dark), if you leave them on the vehicle they stop working in a day bec the sun is too strong for them, they also are not blue as pictured, they are blue under caps with white glow in the dark silicone (the glow is blue) but the white caps just look tackey and they apparently are supposed to be blue when they are fresh, so either they are false advertising or they have really bad/non existing quality control, that is letting by old or badly made products to the customer, this is usable but not as described at all and really not worth the time or money to find all that out, I had high hopes for this product and am very disappointed

Pretty cool looking on the car. Doesn't charge that well in the sun though. Doesn't last that long at night either. But it does look cool when it's lit.

Finally got one that actually works

Just average quality. Look good.

Won’t buy doesn’t work

Good items

Nice quality they matched my wheels but not quite worth the price.
