Competition: we're offering readers the chance to win sets of Bookman bicycle lights in two new colours. The bike accessories are now available in dark jade and clay tones inspired by East German industrial design.

Congratulations to the winners! Greet Van der Linden from Belgium, Souzy Tros from Greece, Daan Zandbergen from the Netherlands, Nick Derickx from Australia and Stuart Turner from the USA all won sets of Bookman bicycle lights.

Easily mounted and detached with elastic loops, the lights are turned on and off using buttons large enough to be operated in gloves. Each pack includes a white front light that attaches to the handlebars and a red light that hooks around the saddle post to shine backward.

The battery-powered, water-resistant lights can be set to flash slowly, quickly, or provide a steady glow. Five winners will each receive two packs of lights; one in each colour. We filmed a short interview with Bookman's Johan Lidehäll speaking about the lights at the Interiors UK trade show last year - watch it here.
