The lightweight Blaze Mk1 is a new addition to Exposure's extensive line of cycling lights. It fills the rear LED niche, but instead of relying on an external power source, it has its own fully rechargeable internal battery. Like Exposure's headlights, the Blaze uses Smart Port Technology Plus. Essentially, it's a cylindrical plug that allows you to insert the smart charger. But, it also enables you to plug in accessories like additional LED taillights, back up batteries, or a remote switch. You can even charge other USB powered devices with the Blaze. It will automatically recognize each accessory and configure the system to take a charge or power accessory lights. The Blaze also shares Intelligent Thermal Management ITM, a patented technology. If the internal temperature gets too high, the light will automatically drop down to the next lowest setting. It will remain at the lower setting until the temperature inside the housing returns to within the normal operating range. The Blaze features a CNC's aerospace grade aluminum body that houses the 80 Lumen Cree XRE LED and 1400mAh battery. This ensures the Exposure Blaze Mk1 is durable and weather resistant for a long life on the road.
