“My granddaughter’s old car died on the interstate on her way home from night class. She had the set I gave her for Christmas. She put one on the roof and one on the back and called me from her seat, calm as anything. She said she watched the cars move over a lane. The next day I made her show me in my driveway, and that night I ordered a set for my own car.”

Now I can sleep when they drive at night
“My son drives home from the hospital after a night shift, an hour on a dark highway. I used to lie awake until he texted me. I put a set of these in his glovebox and a set in my daughter’s. They’re so small you forget they’re there until you need them. I still wait for the text, but I sleep a lot better.”
Dennis K.
The truck behind me moved over a lane
“My alternator quit on I-80 at 11 at night, and my hazards were dimming with the battery. I put one light on the roof and one on the trunk, then sat back in the driver’s seat. In the mirror I watched a semi swing out into the far lane a long way back. Before these, I’d have been standing out there with a flashlight. Bought a set for my wife’s car the next morning.”

“On a night call, the first thing we do is light up the scene, because a driver who sees us late is the biggest danger out there. These give a regular car that same warning. My wife and my daughter both keep a set in their cars.”
Mike D., firefighter
“Thirty years on highway patrol. I told every stranded driver the same thing: get off the road, stay out of the traffic, and make sure the driver behind sees you from a long way back. These lights do that last part.”
Bob H., retired highway patrol
Don’t let somebody you love be the one waiting in a dark car on the shoulder. Keep a set of TerraSignal lights in every car your family drives.
Your hazards help, so keep them on. But they sit low on the car, they die when the car’s battery dies, and from far back at night they look like any other car. TerraSignal runs on its own battery and flashes a 360° ring of red and amber from up on your car.
How far away can drivers see it?
Up to a mile away at night on a straight road. Rain, fog and curves bring that distance in, which is why a light on every side of the car matters.
How many lights do I need?
Enough to light the car from every side: the roof, the back and the hood. Then get a set for every car your family drives, because the car that breaks down is often your daughter’s or your husband’s, not yours.
Will it stick to my car?
It holds on steel, which is what most roofs, trunks and hoods are made of. Some cars use aluminum or glass in places, and no magnet holds there. Hold a fridge magnet to the spot: if the fridge magnet sticks, TerraSignal will too.
Does it need my car’s battery?
No. Each light runs on its own rechargeable battery, so it keeps flashing even when your car is completely dead. Charge it by USB at home and keep it in the glovebox.
What about rain and snow?
It’s waterproof, so rain and snow don’t stop it. If it lands in a puddle it floats, and it keeps flashing even after a car drives over it.
Can I change how it flashes?
Yes. It has 8 flash modes, including SOS, and three white LEDs on the front that turn it into a flashlight when you need to see.
Is it only for breakdowns?
Use it any time you’re stopped where drivers need to see you: a flat tire, a fender-bender, a deer on the road, or a long wait for the tow truck.
What if I change my mind?
Send them back any time in the 120 days for a full refund. No questions asked.
Why can’t I buy this on Amazon or eBay?
We sell direct so we can guarantee real TerraSignal lights, the full 120-day guarantee, and this price. Copies on marketplaces tend to fail at the one moment they’re needed.
SAFETY NOTE: TerraSignal is a roadside warning light that helps drivers coming up behind notice a stopped car. It does not direct traffic, and it does not replace your hazard lights or a call for help. Never step into traffic to place it. In an emergency, always call 911.
