Worn With Pride

★★★★★
Verified Buyer

Best truck upgrade I’ve done, hands down.

“Stuck it on in five minutes, no wiring. Opens my door and the badge lights up the driveway. Two guys at the station already asked me where I got it.”

Crisp even in the rain. Zero flicker.

“Not a cop, I just back the blue. It’s bright and razor sharp on the pavement, auto on/off just works. Looks unreal at night.”

Bought it for my dad. He teared up.

“My father wore the badge for 25 years. He kept opening the door just to watch it. Best gift I’ve ever given him.”

Fits my Tahoe perfect. Waterproof is legit.

“Through a full winter now — snow, salt, car washes. Still bright as day one. Charge lasts weeks. Worth every penny.”

Everyone at the gas station asks about it.

“Can’t pump gas without someone asking where I got it. Simple install, looks premium. Ordered a second for my wife’s car.”

Got Questions?

Will it fit my vehicle?
Yes. It mounts inside virtually any car, truck, SUV or cruiser door with the built-in magnet and adhesive pad. No brand-specific parts needed.
Is it hard to install?
Under 60 seconds. Peel the backing, press it inside your door panel, done. No tools, no wiring, no mechanic.
How does it turn on?
Automatically. A motion/tilt sensor lights the projection the moment your door opens and shuts it off when the door closes — so it never drains.
Does it work in rain and snow?
Yes. The housing is weather-sealed and built to handle rain, snow, heat and car washes.
Wireless or wired?
Fully wireless and battery-powered. One set of batteries lasts weeks of normal use — no cutting into your car’s wiring.
Which badges can I choose?
Choose your badge above — the thin blue line flag, the police badge, the sheriff’s star, the K-9 unit, Saint Michael, the thin blue line Punisher, or Hold The Line.
How long does shipping take?
Free shipping with tracking. Most orders arrive within 7–12 business days.
What if I’m not happy?
You’re covered by our 30-day guarantee. If it arrives damaged or doesn’t perform, contact us for a replacement or refund.
