The smart safety light

Are you riding in a group and need to brake? The red light reacts immediately and emits a brake light. Are you on the road and are being illuminated by a vehicle? The red light always recognizes how much light you need and adapts the luminosity to your surroundings. So you can always be seen perfectly, even in strong ambient light, and automatically save power when you need less power.

Fast and universal

The universal holder guarantees you quick, easy and secure attachment to all seat posts between 22 and 55 millimeters in diameter.

Charging via USB

You simply charge your red light using a standard USB. After the charging process, seal the charging socket with the plug protection.

Robust and safe

The waterproof and shockproof hardware is built for everyday use in wind and rain. The high-quality aluminum housing and the robust polycarbonate front cover form an extremely robust unit.

Individually adjustable

Glowing, flashing, pulsing and more: With the red light international you have four different light modes and up to five different dimming levels available. You can quickly and easily switch between the lighting programs or adjust the sensor settings to suit your situation at the push of a button.

  1. Stork

    I bought this years ago and couldn’t be more pleased wit its performance. Seems pricy but its not especially if you care for your safety equipment properly. I replaced the battery several years after using this for <$20 with shipping. return on investment is worth every cent.
