Emergency Brake Light

Introducing Braking Bar, an Emergency Brake Light that alerts following drivers to urgent braking, making them react up to 50% faster.*

A Deadly Problem

Emergency braking causes over 100,000 rear-end crashes per year, for one simple reason — drivers react slowly.**


The last major upgrade to rear-end collision safety came in 1997. Now, there’s Braking Bar.

1974 — Standard Brake Lights

Intended to be stared at for hours in traffic, the third brake light helps gently indicate your car’s braking to the driver behind you.

1997 — Forward collision warning

Some vehicles can alert and protect you from rear-ending another vehicle.

Today — Braking Bar

Drivers react slowly, which means you’re most likely to be rear-ended when you need to brake suddenly. Braking Bar makes drivers react up to 50% faster when it matters most.

How It Works

1. Install

The stick-on installation is secure, and the motion sensor makes it wire-free.

2. Drive

When you brake urgently, the motion sensor activates the ultra-bright, pulsating LEDs.

3. Protect

These attention-grabbing lights make drivers see your car sooner and react up to 50% faster than with ordinary brake lights alone.


60-second installation

No wires, tools, or charging

Strong, non-damaging adhesive

Built-in motion sensor

Activates when braking forcefully

Ultra-bright, pulsating LEDs


Works in All Climates

Tested in the hottest deserts, thermal chambers, and the coldest winters

Anti-Glare Technology

The light output always stays focused on the driver behind you to maximize effectiveness and eliminate distraction.


The sleek design fits almost all makes and models and automatically self‑calibrates instantly upon installation.

For Everyone

From commuters to livery drivers and families, Braking Bar is engineered to protect everyone on the road.

Legal Everywhere

Braking Bar has multiple operating modes built-in, adjustable at the flip of a switch, so it’s legal throughout the U.S. and worldwide.

4-Year Battery Life

Unlike most electronics which require charging, Braking Bar checks braking force over 100 times per second yet still uses an ultra‑low power architecture.



Braking Bar definitely adds on the feeling of security, especially driving around with a little baby in the city in the hectic morning commute. Super easy to install and sleek design, and no wires! Really worth the money!

Braking Bar is designed to work with all passenger vehicles with a fixed or hinged back window. However, it does not work on convertibles nor vehicles with rear windows that slide down, as the product may not have adequate clearance when the rear window is lowered. Window tinting darker than 35% VLT will have a noticeable impact on output brightness.

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. See the footnotes below for the complete studies.

Braking Bar’s non-rechargeable battery is projected to last four years for the average driver. This duration is based on lab data and can vary widely as it is affected by temperature and driving style.
