Our guess is a 2Fer 2Fer sounded odd to the marketing folks at Blackburn, so the experts decided that when selling the versatile 2Fer USB light in pairs, the Blackburn 2Fer USB Light 2-Pack was named. You get a pair of the front or rear 2Fer USB lights in a single package and save $5 in the process. That works!

Blackburn Design puts forward a fun little lighting option, the 2Fer concept. This USB rechargeable, compact light has run modes for front or rear use, hence "2Fer". As a front light, the 2Fer USB Light has a steady 60 Lumen output; and as a rear, a steady 20 Lumens, both for 1.5 hours of run time. Both 2Fer options also feature a Flash mode, with 5 hour run time.

The 18 gram 2Fer USB has a sealed USB interface, with a IP65 water resistance rating. The Lithium Polymer (LiPo) battery has 3 hour charging time via a standard USB output. The light body itself measures out to 1.8" tall, 1.3" wide and 0.8" deep. The compact mount straps onto any size bar or seatpost, and the clip that locks the light body into place on the mount can also be used on a pack strap, saddle bag, rack, or waist band.

The 2Fer USB Light 2-Pack offers a complete simple, versatile "be-seen" lighting system that anyone who commutes via bike, bus, or on foot can appreciate. Blackburn supplies the USB charging cable, light, and mount. You supply the need.
