A simple solution to a complex problem, the Sigma rear brake light allows motor vehicle drivers to know when you’re braking on your bicycle. Small at 3 x 3 cms/1.18 in and light (weight wise @ 7 grams/ 0.25 oz 🙂 ), easy to install (you just need a 2.5mm hex key) and simple in operation the light uses your rear brake cable to activate. The light uses an LED and a 1025 button cell battery that should last approximately 100,000 braking processes and it’s available in 5 different colours to match your mighty steed.
A cheap and easy solution to make cyclists (hopefully) more noticeable on the road. Available from Sigma for the light sum of $9.99.
