Lupine Rotlicht

What’s cool about it

The Lupine Rotlicht gets brighter when the cyclist comes to a stop. It also gets brighter when there’s more ambient light, like a car shining lights on it.

What is it

The Lupine Rotlicht is a 160 Lumen light with four different light modes are available: steady, flashing, wave pulse, and pulse. It has an accelerometer that allows it to function as a brake light. When you pull on the brakes and slow down significantly or come to a stop, the built in acceleration sensor turns the light brighter to gain more attention on the streets.

It is also light sensing and has automatic light adjustment depending on the ambient light. If for example a car comes closer, the light turns brighter, allowing the rider to become more visible.

Video: Test with the Lupine Rotlicht Tail Light. Tail Light was shot from 20 yards away with a camera at fixed exposure. The light was pointed at the camera then turned to the side. Different flash modes were activated.
