THE BRAKE LIGHT RIDERS TRUST
HELMET BRAKE LIGHT
Brake Free // USB–C
Storm-Trooper White
"Cars finally see me. Three near-misses last year, zero since."
— Jelle M., Utrecht
"Mounted in 2 minutes. Charges fast. Just works. No-brainer for night rides."
— Sara V., Amsterdam
"Bright as hell. No app fatigue. Wife stopped worrying about my commute."
— Mark T., Antwerp
"Goed product. Detects engine braking, which my tail light never did."
— Pieter K., Eindhoven
Your standard brake light only fires when you touch the lever. It stays dark when you engine-brake, downshift, or roll off the throttle through a corner. That is the gap. That is where the car behind you has no warning. Brake Free exists to close it.
The USB-C model is the current flagship. Same proven 100-LED ring and IMU detection as the original, with a slight edge in terms of faster charging through the (now standard) universal USB-C connector.
No app. No wires. No permanent modifications to your helmet.
Ride modes: Three modes, switchable on the unit through a singel button press. Stealth Mode recommended — 16 LEDs at rest, full 100-LED ring on any deceleration event. Maximum contrast without the clutter.
Detection: IMU-powered. Activates on braking, engine braking and downshifting — anything that slows the bike.
Charging: USB-C, 2A fast charge. Universal USB-C to USB-C cable included. 80% in 30 minutes with a QC charger or powerbank.
Runtime: 8–14+ hours per charge.
Mount: Click-in locking mechanism. 3M VHB adhesive. Installs in minutes, no drilling or permanent helmet modifications.
Compatibility: Full-face, open-face, adventure, and flip-up helmets.
Give them ZERO excuses not to see you.

THE VISIBILITY GAP IS REAL
Engine braking. Downshifting. Every deceleration your tail light ignores. Brake Free detects all of it — mounted on your helmet, at eye level, where drivers actually look.
Engine braking. Downshifting. Easing off — none of it fires your motorcycle brake light. Plus drivers look at eye-level — Brake Free is helmet mounted and sits right where it matters most. Fully wireless, accurate and automatic. Your helmet is about to get a serious upgrade. Brake Free — Always on, always visible.


Brake Free weighs about 200 g (around 7 oz). It’s designed to stay balanced on your helmet without feeling bulky.
Brake Free mounts to your helmet—it is not wired into the bike. It uses onboard sensing so you don’t need a physical connection to the motorcycle.
It detects deceleration using built-in sensors and lights up when you slow down, so following traffic gets a clear brake-style signal without tapping into the bike’s wiring.
Brake Free works with many full-face and modular helmets using the included mounts. Fit depends on shell shape and size—use our compatibility lists to confirm your model and whether you need the XL mount.
Some larger or specific helmet shells need the XL mount for a secure fit. See the published XL-mount compatibility list for your exact model before installing.
Certain helmet shapes or configurations aren’t compatible. Check the “does not work” compatibility list so you don’t mount on an unsupported shell.
It’s built for motorcycling, but many riders also use it on other light electric vehicles where a helmet-mounted brake light helps—e-scooters, e-bikes, etc.—as long as mounting and local rules allow.
It doesn’t sync with turn signals. Brake Free focuses on deceleration visibility—strong rear lighting when you slow—rather than copying indicator flashes.
Mode 1 (Standard), Mode 2 (Safety), and Mode 3 (Stealth) change how bright and assertive the rear LEDs are. Stealth is the most discreet; expect the longest runtime in that mode (on the order of many hours, depending on use).
On startup, the LED blink pattern indicates charge level—for example, three blinks can mean roughly 75–100% and two blinks roughly 35–75% (see your quick-start guide for the exact mapping).
You’ll get a low-battery indication through the unit’s LED behavior; check the guide for the specific low-battery pattern so you can charge before your next ride.
Runtime depends on mode and how often you brake and ride. Many riders see on the order of roughly 8–12+ hours in typical use; Stealth mode can stretch toward longer runtimes.
Brake Free uses a rechargeable 18650-format lithium-ion cell inside the unit.
The battery is built for service through Brake Free’s support/warranty process—not as a user-swappable consumable. Contact support if you think the battery needs replacement.
Charging circuitry is designed for normal USB charging; avoid unofficial chargers and follow the charging guidance in the manual.
Yes—you can top up from a USB power bank or bike USB outlet using a suitable USB-C cable, same as phone-style portable charging.
Charge time depends on the charger and how depleted the battery is; use a decent USB-C power source and expect a typical full charge on the order of a few hours (see product specs for the rated charge rate).
