The head and tail light options for bikes can be incredibly daunting, we know. If you're the slightest bit indecisive, you'd better be prepared to spend a considerable amount of time trying to choose between dozens of different models. If you know simplicity is what you're after, we'd recommend the Blackburn 2Fer USB Light. Able to double as either a front or rear light, the minimal 2Fer emits up to 60 lumens on front mode and 20 on rear, helping you stay visible in traffic or during rides that end under dark skies without overburdening you with too many features. The included battery recharges via a USB cable, and you can choose between just two refreshingly basic modes: flashing and steady.
