From the Founders of eircore
We started eircore in 2025 — small team, big obsession with making driving less stressful.
Our early products were about safety. EirSignal is different. It's not about safety — it's about sanity.
Because yelling at other drivers gets you nowhere. Honking just makes you another part of the noise. But pressing one button on a remote and flashing exactly how you feel? That's catharsis on demand.
Every order comes with our real email — support@eircore.com. Reply to any of our emails and a human (probably one of us) writes back within 12 hours.

Frequently Asked Questions
Will this damage my windshield?
No. The 3M adhesive removes cleanly with no residue.
Is this legal?
Yes. EirSignal displays expressions, not text — no different from a bumper sticker. Amber, non-flashing LEDs comply with traffic codes in most US states. (Check local laws if you live somewhere strict.)
How long does shipping really take?
Honest answer: 7-10 business days to the US on average. We ship from our overseas fulfillment partner within 24 hours of order. Tracking link emailed when it ships.
What if it doesn't work or I don't like it?
90-day money-back. We pay the return shipping label. Email us, we send a label, you ship it back, we refund 100%. No restocking fees.
How long do batteries last?
3 AA batteries last 3-4 months with normal daily use. Lithium AAs last longer in cold weather (we recommend Energizer Ultimate).
Wait, do I HAVE to use AA batteries?
No. EirSignal also has a 5V USB charging port on the back. Plug in a standard USB-A cable for permanent power — no battery swaps ever. Use whichever works for your car setup.
Are batteries / USB cable included?
Currently no — international shipping rules make batteries expensive to include, and any spare phone cable from your USB-A days will work. A 4-pack of AA at any drugstore is under $5.
Is it weatherproof?
The unit is rated rain, snow, heat, and wind resistant (ABS plastic + sealed). But it's designed for INDOOR mounting (inside the rear window), so weather barely touches it anyway. Operating temp -10°F to 140°F.
How many LEDs?
302 LED beads, rated for 50,000 hours of use. Bright enough for midday sun, not blinding at night.
Will the remote interfere with my key fob?
No. EirSignal uses 433MHz, separate from automotive RF.
Can I customize the combos?
The 4 combo buttons are pre-programmed (Smile→Thumbs-up, Angry→One-Finger, Sad→Pause, Naughty→Love-You). With 4 emoticons + 4 gestures + 4 combos + 2 cycle modes, you've got 14 patterns covering most real driving situations.
Does it work for trucks / SUVs / vans / off-road?
Yes — universal compatibility. Cars, SUVs, trucks, off-road vehicles. Even works on ships, forklifts, snowmobiles if that's your life. Any vehicle with a flat-ish rear window? It works.
How do I contact you if there's a problem?
Email support@eircore.com — a real person reads it and replies within 12 hours, including weekends.

Let customers speak for us
I picked this up after a near-miss where someone almost rear-ended me and I just laid on the horn out of panic — which made everything worse. Now I use the warning gesture or the sorry face and people actually respond better. It's stupid that this works but it does. 14 different signals to pick from gives you way more options than just honking.
One in my car, one for my brother, ordering one for my dad's birthday. The thank-you wave gesture is my favorite — feels less aggressive than just honking when someone lets me change lanes. Battery still hasn't died on the original I bought 2.5 months ago and I use it every day.
If you live in LA you understand. The 405 is a parking lot every day. Having a way to thank people for letting me in (without rolling down a window) has weirdly made my commute less hostile. The thumbs up gets used way more than the middle finger honestly. Plugged it into USB so I never have to swap batteries.
16-year-old daughter saw it in my car last week and asked if she could use it for her drives to school. That's the highest compliment I've gotten as a mom in years. Side note — the smiley really does cut down on road rage incidents around me. People just laugh and move on.
Bought one for my husband as a gag gift, ended up loving it so much for my own commute that he kept stealing it. Now we both have one. The remote is small enough to fit in the cup holder. Battery has lasted 3 months so far on the same set of AAs.
Got this because I was tired of road raging in silence. First week I had it I used the smiley face like 50 times — every time someone let me merge I'd flash the thumbs-up and they'd usually grin and wave. The middle finger I've used twice and both times the guy behind me started laughing instead of getting madder. Genuinely makes traffic less stressful.

Park near the bridge for work. Heard too many stories. Defender Lock + tinted windows + dash cam = I sleep at night. The lock is the cheapest part of the setup and probably the most important.
— Ramon V., El Paso, TX
January 2026 we hit -8°F for a week straight. PVC coating stayed flexible, cable didn't snap, lock mechanism still turned smooth. I was honestly surprised — cheap locks freeze up. This one didn't.
— Brian H., Cleveland, OH
Got the 2-pack. My dad lives alone in a condo lot where 6 cars have been broken into this year. He's 71 and was nervous about how complicated it would be. He's been using his for 3 weeks. Zero issues, total peace of mind for both of us.
— Michelle A., Stockton, CA
Realized this isn't about whether a determined thief could cut the cable. Of course they could. It's about making MY car the harder target so they pick someone else. And on my block it's working. Untouched 5 months.
— Damon B., Houston, TX
I'm not great with gadgets. My son set this up the first time and it took 30 seconds. After that I do it myself every night before bed (we park outside). Three keys came with it — I have one in my jewelry box just in case.
— Patricia R., Albuquerque, NM
Drive for Uber Wednesday-Sunday nights. Park in some sketchy spots between rides. Defender Lock goes on EVERY time I leave the car for more than 5 minutes. Bathroom break? Lock on. Dinner stop? Lock on. Habit now.
— Carlos D., Los Angeles, CA
Live in Highlandtown. Cars on our block get hit constantly. Mine's been parked street-side for 4 months with Defender Lock on it every night. Untouched while two neighbors got broken into. Visible deterrent absolutely works.
— Greg N., Baltimore, MD
Bought this for myself after my Hyundai got broken into. Daughter saw it, asked about it, ended up buying her own for her Elantra. Now both our cars in the driveway have the yellow lock. Whole house feels safer.
