The VAUDE TOOL LED practical bag is not only easily attached to the saddle with our Twist-Adapter system, it’s also “OSRAM ready”! This means that an OSRAM LED optical fiber kit (sold separately) can be attached to the bike bag for 270-degree visibility in combination with a compact portable battery. So you won’t have to worry about extending your ride into the evening, and you’ll have better visibility on the road during transitional seasons as well. The OSRAM light takes up hardly any space and leaves plenty of room for tools, energy bars or a lightweight windproof vest. With reflective elements and a practical attachment point for a safety light.
