High-tech stereo-sensors scan the ambient light and automatically switch the SL from daytime running light to full beam. This function is especially handy at high speeds, when you may not have time to react.


The heart of the SL is composed of 12 high intensity LEDs and the world's first dual Aspheric Lens System for bike lights. Their extremely robust and high quality aluminum body protects the SL from shock, dust, and water.

The SL is a special member of the Lupine family of lights. Not only is it compliant with strict e-bike light standards, but it also directs 100% of its 900 lumens directly on your path. The SL is designed like a car headlight and doesn't glare any other road users.


Mounting the SL A is very simple and compatible with Stem widths of 39-51mm. 


The SL is incomparable. Its unique look is due not only to the distinctive "daytime running light" but above all to the development performance of our engineers. With the SL, they created the smallest and lightest lamp in its class.



Lupine offers 20-plus years of precision-manufacturing and high-tech innovation- made in Germany.

   Great Commuter Light, August 11, 2017  By Anonymous (PLEASANT HILL, CA)(Verified)
This light makes my commute less stressful because I no longer need to worry about blinding oncoming drivers and pedestrians. The only things I would improve are to have a remote and a brighter high beam for fast downhills.
