How It Works

With its built-in battery and motion sensor, Braking Bar doesn’t have any physical connection to your braking system.


Strong adhesive enables Braking Bar to secure to any window in seconds. There are no wires, screws, or charging – it’s that simple.


Once attached, the powerful LEDs pivot so they perfectly face following drivers, no matter what your window’s angle.


The settings are easy to follow, and with multiple operating modes, Braking Bar is highly versatile and adapts to any vehicle.


Once attached, the system precisely calibrates to your vehicle so that a built-in motion can determine your braking force without any wires or connection to your braking system.


As you drive, the built-in motion sensor checks your braking force over 100 times per second. Then, the next time it senses that you’re braking hard – approximately 70% of your maximum braking force depending on your car – it activates the LEDs.

The LEDs have two operating modes: STEADY and PULSE. In STEADY mode, the LEDs output the maximum legal illumination. In PULSE mode, the LEDs also pulsate. Both modes are designed to get maximum attention, and some drivers and car companies prefer one design over the other. The system also has a brightness setting to accommodate window tints as dark as 35% VLT.


Ordinary brake lights are stared at for hours at a time in traffic. Because of this, they are designed to not get too much attention, or else they would become annoying. This has a downside – when you need to brake quickly, normal brake lights are too subtle to get attention quickly.

That’s why Braking Bar is so important; when braking forcefully, Braking Bar’s attention-grabbing lights make drivers see your car sooner and react up to 50% faster* than with ordinary brake lights alone.

Further, by activating only on hard braking, Braking Bar is never annoying, and always welcome.

Simple and Effective

An Emergency Brake Light is most effective when it is bright, mounted high, and activated only on hard braking. Braking Bar is a user-friendly, top-of-the-line safety technology that keeps you and your loved ones safe.

Warning: There is no substitute for safe driving. Braking Bar is a supplemental brake light and not a replacement for required brake lights. There is no safety product that can prevent every rear-end collision. Referenced facts refer to findings from professional studies on Braking Bar’s underlying technology.
