WORLD PREMIERE : L.E.S.S. nano active fiber technology is integrated for the first time on a car at the GIMS‘17.

Geneva, March 9th 2017 – World premiere: Daytime Running Lights (DRL) made with L.E.S.S. nano active fiber technology are displayed on a car at the Geneva International Motor Show 2017 (GIMS’17). It represents the longest and thinnest DRLs ever made.

Thanks to the versatility of its fiber laser technology, L.E.S.S. is able to adapt to the increasing demands of car designers for thin, low weight and bright automotive lighting. The thinness, the flexibility and the three-dimensional lighting nature of L.E.S.S. technology allows for the creation of unprecedented car lighting signatures.

Dr. Yann Tissot, CEO of L.E.S.S.  SA, says: “We have been working hard for years with different players of the car industry to be able to deliver energy efficient and low weight headlights with inspiring designs. Having our technology displayed for the first time to the end users represents a key milestone for us. We are proud to have delivered beautifully designed lighting modules based on our unique technology that, I am convinced, will have a strong impact on the future of the automotive lighting industry.”

Longer, lighter, thinner, brighter, and more uniform than today’s LEDs lighting technology, the nano active fiber technology from L.E.S.S. unveils an infinity of lighting design possibilities. Its low weight potentially contributes to an enhancement of the car performances and a reduction of its fuel or electricity consumption. L.E.S.S. disruptive technology opens new routes for designing a new generation of automotive lighting.

About L.E.S.S. SA. L.E.S.S. SA is a fast-growing high-tech company with international activities located in Lausanne, Switzerland. L.E.S.S. SA develops, manufactures and markets unique lighting systems based on its proprietary nano active fiber technology. L.E.S.S. SA has been awarded Best Swiss Startup in both 2015 and 2016.
