SERFAS USL-11 / UTL-11 | High-Visibility Safety Light for Day and Night

The entire body illuminates, ensuring you are seen. A safety light that adds peace of mind to your daily ride.

The role of a light isn't just to illuminate the road. Clearly signaling your presence to others is also an essential element for safe riding.

The SERFAS USL-11 / UTL-11 is a safety light with a unique structure where the entire transparent resin body illuminates. It ensures high visibility not only from the front and rear but also from the sides, making your presence clearly known at intersections and in busy urban areas with heavy traffic.

With 300-degree visibility and a maximum visible distance of approximately 1000m, it is effective as a daytime running light and is suitable for a wide range of situations, from commuting to school, city riding, and night rides.

The compact, USB-rechargeable body weighs only 29g. In addition to easy installation with a silicone strap, it also supports clip attachment, allowing it to be attached not only to bicycles but also to bags and clothing.

The main appeal of this light is its extremely high visibility. Since the light is clearly visible not only from the front but also from the sides, it provides a sense of security in places with high risks of contact with vehicles, such as intersections and residential areas.

It's easy to attach and lightweight, so it doesn't detract from the appearance of your handlebars or seatpost area. This safety light is highly recommended for daily commuting to school or work, and especially for anyone who wants to "prioritize safety first."
