Why HaloSiren
From early morning runs to late-night walks or trips to unfamiliar places, HaloSiren keeps a loud warning one pull away.
Sound + light
A 130dB siren and a bright strobe together
Basic alarms only make noise. HaloSiren pairs a 130dB siren with a flashing LED strobe, using both sound and light to disorient an attacker and attract help.
"I've tested it, and wow, it's loud!" Sarah F., New York
One pull
Activates in one quick motion
The pull-pin design sets off the alarm and strobe at once, with no buttons to find or sequences to remember. Push the pin back in to silence it.
"It's loud, effective, and so simple to use." Mary S., Florida
Compact
Small enough to carry everywhere
Clip it to your keys, purse, backpack or running belt. It is light and discreet, so you are never without it.
"It clips right to my backpack and I barely notice it's there until I need that security." Ashley K.
No phone needed
Works without apps or signal
Unlike smartphone apps that need a connection, HaloSiren works on its own. There is no setup and no monthly fee.

Frequently asked questions
What makes HaloSiren different?
It combines a 130dB alarm and a bright LED strobe in one compact device. The sound and light together help disorient an attacker and attract help, and the one-pull activation works without fumbling for buttons.
How loud is it?
The alarm is rated at 130dB, an ear-piercing sound meant to startle an attacker and let people nearby know you need help.
How do I turn it on and off?
Pull the top pin to start the siren and strobe. Push the pin back in to silence it.
Can it go off by accident?
The pin needs an intentional pull, so accidental activation is unlikely during normal carrying.
How long does the battery last?
The maker lists up to 12 months of standby use and several hours of continuous sound once activated. Check it every few months.
Is it waterproof?
The maker lists a weather-resistant design rated IPX7, so it keeps working in rain or snow.
