The Giant Numen Alumbra TL Rear Light is a super lightweight, helmet-mounted safety light designed for riders who want a clean, integrated visibility solution without bulky seatpost mounts. It clips directly onto compatible Giant and Liv helmets, keeping your setup minimal while improving rear visibility on the road.
Despite its compact size, it delivers up to 20 lumens of output, making it suitable for commuting and urban riding where being seen is the priority. The design uses a quick magnetic/clip mounting system, allowing fast on-and-off removal for charging or storage.
The light is built for everyday use with multiple flashing and steady modes, plus a low battery indicator and memory function, so it remembers your last used setting. It’s also lightweight at around 17 g (without mount), making it barely noticeable when riding.
Water resistance is rated at IPX4, meaning it handles rain and road spray without issue—ideal for regular South African commuting conditions.
Key Benefits
Helmet-integrated design – Clips directly to compatible Giant/Liv helmets for a clean setup
20 lumen rear visibility – Designed for daytime and urban safety riding
Quick magnetic/clip mount – Easy on/off for charging and storage
Multiple light modes – Flashing and steady options for different conditions
Ultra-lightweight (±17 g) – Minimal weight and no drag on the bike setup
IPX4 water resistance – Reliable in rain and wet road conditions
Who Is This Best Suited For?
The Giant Numen Alumbra TL is ideal for commuters and road cyclists using compatible Giant or Liv helmets who want a lightweight, integrated rear light focused on visibility and simplicity rather than high-power output.
