2015 Lights Shootout

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.

4.5 out of 5 Stars

Technologically, this is an awesome light with German engineering and best-of-breed safety features. But not everyone is ready for the $125 price point. But if you want to be safe and you're ready for a light that will last decades, the Rotlicht is a good option.
