When you're commuting regularly, a reliable light is a crucial part of your setup because, unless you only commute during midsummer, chances are good that one or both parts of your commute will take place in the dark at some point. Having a light that can last through traffic and inclement weather is imperative, which are the design principles behind Exposure Lights' Switch Light. It's a durable, urban specific model designed to make your commute smoother and safer in various weather conditions. Emitting up to 350 lumens and encased in weather resistant CNC machined aluminum, the Switch is capable of running anywhere from three hours to a full 24 hours depending on the settings used. If you're unsure of whether you should quickly recharge before heading home, Exposure includes a fuel gauge on the light's body, and its Li ion battery recharges quickly and easily with an included USB charging cable. Like other Exposure products, the Switch attaches and detaches easily with an included quick release handlebar mount so you can swap it onto another frame or take it with you to avoid theft while your bike is unattended.
