Alien Valve Caps — Set of 4
Free US shipping. Made to order and checked out securely through our Etsy shop, where you pick your options.
They charge in daylight and glow all night, on all four wheels.
A sculpted alien face on every cap — the same one from my phone cases, shrunk down to 23 mm. No paint, no sticker, no coating that wears off: the glow is in the material itself, all the way through, so it never fades, chips or peels, even out on the road.
You get all four. One per wheel.
Universal Fit — Read This First
These use the standard .305"-32 Schrader thread, which is what every car, truck, SUV, motorcycle and trailer in the US uses. If you can unscrew the little black cap that came on your tire, these screw straight onto the same stem. No adapter, no tool.
They also fit most bicycles — the ones with the fat, car-style valve. They will NOT fit a Presta valve, the skinny one with the tiny screw on top that road bikes use. If you're not sure, look at your valve: fat and flat on top is Schrader, and these fit.
Screw each cap all the way down until it stops. A loose cap can be knocked off by car wash brushes.
How You Charge Them
Any light. Twenty to thirty minutes in the sun and they're full — a day of driving charges them without you doing anything at all. Under a lamp it takes about an hour, and a UV flashlight fills them in about a minute.
The first twenty or thirty minutes are the show. From there it fades gradually, and in a dark driveway the strongest ones are still visible eight hours later.
The Colors
Every color glows. What changes is the color it glows, and how strong.
GREEN — glows a bright, classic green. The strongest of the five and the one that holds longest.
YELLOW — glows a pale green. Right behind the green.
PURPLE — purple by day, glows electric blue in the dark. Blue reads softer to the eye than green, but it holds almost as long.
WHITE — glows green.
ORANGE — orange by day, glows a creamy yellow. The most subtle of the five.
