Exposure Lights was born from Ultimate Sports Engineering, which was founded in 1990 when production began on the world’s first suspension seat post. Since then, the company has expanded its portfolio to include the Exposure Lights, Ultimate and Exposure OLAS brands, all of which are designed and hand-built in the heart of the South Downs in southern England.

Our team are dedicated to creating products which lead to improved performance, enhanced safety and above all, greater enjoyment of your chosen pursuit.

Exposure Lights has earned a reputation for delivering products of the highest standards, with reliable functionality, durability and best-in-class tech at their core, all backed up by excellent customer service.

Whether attacking technical trails in pitch darkness, exploring the world on a bike-packing adventure or powering along mile after mile on the road, Exposure Lights offer exceptional performance no matter what or where you ride. Our lights feature smart technology that provides additional benefits, combined with powerful lumen outputs and long run times, allowing you to focus on the ride.

Exposure Lights is delighted to help anyone attempting the South Downs Double and we offer our lights on a loan basis to give riders the best chance of completing inside 24 hours. If you would like to chat to our friendly team about loaning lights for your own attempt, then please email [email protected] in the first instance.
