Autolizer H2 Motorcycle Helmet Light — Compact LED Rear Light with G‑Sensor Brake Mode, USB‑C Rechargeable

Autolizer H2 is a compact helmet-mounted LED light that increases rear visibility with flowing light patterns and an automatic G-sensor brake mode.

The Autolizer H2 Motorcycle Helmet Light combines a slim, modern profile with high‑intensity LEDs and an accelerometer that detects braking to switch instantly to a bright red alert. Designed to attach cleanly to most helmets with removable adhesive, the H2 delivers multiple lighting styles, up to 18 hours of runtime on a single USB‑C charge, and a wireless installation that avoids messy wiring or ECU connections.

How does the G‑sensor brake mode improve visibility?

The built‑in G‑sensor senses sudden deceleration and switches the LED array to an unmistakable bright red brake display so riders behind you notice your stop earlier. This automatic change in intensity and color is faster than flip switches and works while you concentrate on controlling the motorcycle.

• Accelerometer‑triggered automatic transition to bright red LEDs
• High contrast color change to draw attention in traffic
• Instant activation with no manual input needed

What lighting modes are available and when should I use them?

The H2 offers ten flowing light patterns plus steady, pulse, and flash options to match daytime, dusk, or night conditions and to suit personal preference. Use steady for consistent visibility, pulse for urban commuting, and flash modes to stand out in heavy traffic or low‑visibility situations.

• Ten flowing patterns for motion‑accentuated visibility
• Steady/pulse/flash presets for different riding contexts
• Easy mode cycling with a single onboard control

How long does the battery last and how do I recharge it?

The integrated rechargeable battery gives up to 18 hours of runtime depending on the selected mode and brightness. Recharging is simple with the included USB‑C cable; a full charge replenishes the battery quickly so the light is ready for multi‑day trips.

• Up to 18 hours runtime on lower brightness modes
• USB‑C charging for fast, modern connectivity
• Charge indicator shows battery status during charging

How do I attach and maintain the helmet light?

Autolizer H2 installs without wiring: place the light on the helmet with the durable removable adhesive pad supplied, press firmly, and let it set. The low‑profile housing resists wind and weather, and the adhesive can be replaced if you switch helmets.

• Wireless design — no harness or ECU connections required
• Durable removable adhesive for secure mounting and easy removal
• Low‑profile weather‑resistant housing for daily use

Who is this for? The Autolizer H2 is aimed at motorcycle and e‑bike riders who want a simple, reliable way to increase rear visibility without permanent wiring. It's suited for commuters, recreational riders, and anyone who wants a compact, rechargeable safety light that blends modern styling with practical features like automatic brake detection and a long battery life.
