Emergency brake light for vehicles

The Maxsa Innovations Braking Bar uses ultra-bright pulsing red LEDs that activate on hard braking to alert following drivers. It attaches directly to the rear window without wires and fits nearly any vehicle. A motion sensor and battery power the unit so no electrical connection is required.

Battery life and installation limits

The internal battery lasts four years for the average driver before replacement is needed. The wire-free design means the unit cannot draw power from the vehicle charging system. Motion-sensor activation depends on detecting hard braking events rather than a direct brake-circuit link.

Award-winning build with suction mounting

The product won the SEMA Launchpad award for best new automotive item. It simply sticks to the rear window glass using a suction mount for quick fitting and removal. The self-contained housing keeps the LEDs and electronics sealed against weather.

Questions about this item

How do I decide between the wired and wire-free versions of the 29955 Braking Bar?

The 29955 model is completely wire-free; it uses a motion sensor and internal battery that lasts four years for the average driver, so no wiring version exists for this item.

What does the 50% faster reaction claim mean when the bar is mounted on my rear window?

The pulsing red LEDs activate automatically during hard braking, alerting following drivers so they can react up to 50% faster than with standard brake lights alone.

Does the 29955 Braking Bar use a specific wireless protocol or vehicle interface to detect braking?

No, it has a built-in motion sensor that detects hard braking directly, requiring no connection to the vehicle's electrical system or a wireless standard.
