I Cast Check Engine Light (Wizard) Bumper Sticker
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.

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.”

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.”
