I Cast Check Engine Light (Wizard)
Description
I CAST (Check Engine Light) – Funny Bumper Sticker or Car Magnet
Your dashboard light may warn you of doom, but this time, it’s magic. The “I CAST (check engine light)” bumper sticker is what happens when wizards discover vehicle maintenance and immediately regret it. Whether your car runs on gas, spells, or sheer spite, this weatherproof beauty declares to every passerby: you don’t fix problems—you summon them.
When that orange light flickers on, most people panic. You? You grab your staff and bumper sticker and mumble an incantation, and keep driving. Because this isn’t a malfunction—it’s a manifestation. A hex. A curse. A vibe.
This funny bumper sticker immortalizes that chaotic energy: a wizard with robes full of crumbs, staff raised high, casting one single spell—and it’s your check engine light.
Stick it proudly on your bumper, your laptop, your toolbox, or anywhere your mechanical gremlins reside. It’s bold, dumb, mystical perfection—aka Frog Mustard’s entire brand ethos.
Premium Vinyl for Chaotic Adventurers
Crafted from thick, high-quality vinyl, this sticker isn’t here to mess around. It’s UV-resistant, waterproof, and able to endure your next six failed emissions tests. Whether it’s your 2004 Honda Civic or your broomstick, this sticker stays stuck.

Prefer Temporary Magic? Choose the Car Magnet.
Not ready to commit your sorcery permanently? The magnet version is your spell of choice. Same bold design, same chaotic vibe, but on a thick, glossy, removable 30 mil magnet. It sticks to your trunk, your fridge, or your coworker’s car if you’re feeling mischievous.
It removes cleanly, so you can take it off before visiting your in-laws or going through a car wash (we assume you don’t do either often).
Lore: The Wizard Behind the Light
Every Frog Mustard design starts with a fever dream. This one began when someone said, “What if the check engine light wasn’t a warning—it was a spell?”
Boom. Instant prophecy. The wizard appeared. The light glowed. A legend was born.
This isn’t just a funny bumper sticker—it’s a lifestyle. It’s for everyone who drives with the check engine light on because they believe in something greater. It’s for the unbothered, the overconfident, the ones who think “mechanic” is just another word for “necromancer.”
The Frog Mustard Guarantee: Chaos Is Weatherproof
Every Frog Mustard sticker and magnet is printed in-house using premium weatherproof materials. We’ve sold tens of thousands worldwide to people who think normal bumper stickers are boring.
-
Shipped globally within 1–2 days.
-
Designed by chaotic geniuses in the PNW.
-
Guaranteed to get at least one honk, laugh, or confused stare per drive.
Our motto: if you’re not laughing at your own car’s misery, what are you even doing?
Why You Need This Sticker
-
It’s hilarious, even without words. The little orange light says it all.
-
It’s a perfect conversation starter—or conversation ender.
-
It pairs perfectly with other Frog Mustard classics like “Drywall Fears Me” or “Don’t Hit Me – My Piss Jugs Are Full.”
-
It’s the ideal energy for anyone whose vehicle “just sounds like that.”
Whether you’re a fantasy nerd, a highway menace, or someone one bad rattle away from becoming a wizard yourself, this bumper sticker has your name written all over it (probably in runes).
Easy Application, Instant Regret
Peel. Stick. Laugh.
That’s it. No spells, no tools—just pure chaos.
Clean the surface, press it on, and whisper, “I CAST CHECK ENGINE” to bind the spell. The vinyl version sticks firm; the magnet version holds strong but pops right off when you need to flee the kingdom (or the mechanic’s parking lot).
Both options remove cleanly—because while the humor is permanent, your mistakes don’t have to be.
Built for Every Element (and Some That Don’t Exist Yet)
Rain, heat, or dark night of the soul—this weatherproof sticker doesn’t flinch. It’s laminated for 5+ years of outdoor use, which is at least four years longer than your warranty.
Even if your car gives out, the sticker will still be there, glowing faintly on the side of the road like a cursed relic.
When someone asks, “You gonna fix that light?” you can simply say:
“No. I cast it.”
Frequently Asked Questions
Q: Is this the same design for both the bumper sticker and the magnet?
A: Yep! You choose whether to embrace chaos permanently with the vinyl sticker or go commitment-free with the magnet version. Both feature the same wizardly art and weatherproof finish.
Q: Will this survive outdoor weather?
A: Absolutely. Each sticker is UV-protected, waterproof, and built to withstand everything from rainstorms to eldritch energy. This weatherproof sticker has survived mail trucks, snow, and at least one volcano.
Q: Where else can I put it?
A: Literally anywhere flat—laptops, coolers, water bottles, spellbooks, car doors, cauldrons, you name it. The magnet works great on metal surfaces too (hatchbacks, fridges, mysterious iron gates).

❗ DISCLAIMERS:
Mockups:
Mockup images are not to scale. May be larger in images for viewability. Colors may vary slightly.
Application Disclaimer:
– We can’t offer refunds for application to textured, plastic, or dirty surfaces, or for poor application practices.
– Frog Mustard products work best on glossy, smooth, clean, dry surfaces.
– Many coolers, kayaks, vehicle cladding, and similar items are made with low surface energy (LSE) plastics, which make it hard for adhesives (even premium vinyl) to bond.
– You assume the risk if you apply to a weird or incompatible surface.
👉 If you're applying to an LSE plastic and love our designs, message us — we’re happy to chat about higher-tack vinyl options for tough surfaces.
💡 For DIY adhesion help, many folks use Mod Podge, 3M Super 77 spray adhesive, or apply a little heat and pressure during application.

Air Bubbles (Magnets):
Small air bubbles under magnets are normal and usually disappear with time/heat.
Magnet Compatibility:
Many modern car bumpers are plastic and won’t hold magnets — try your trunk, doors, or side panels instead. Test a magnet on your car before purchasing. We cannot refund for those that do not check.
Longevity:
While our materials are built to last, extreme weather or improper surface prep can shorten product life.
Duplicates (Mystery/Misprints): Mystery and misprint packs may include duplicates. That’s part of the gamble. Misprints are subject to what is on hand that has been misprinted. If you do not want duplicates, buy a non-misprinted bundle.
Design Ownership:
All designs are original and created for humor/novelty. Parody and satire are protected speech.
No Custom Orders via Notes:
We can’t honor custom requests left in order notes for non-custom products. Please contact us before purchasing.
Stolen or Lost Mail:
Once your package is marked delivered, we unfortunately can’t replace lost or stolen mail. Please ensure your shipping address is correct and secure.
