The PowerPlus Swallow bike light set helps you remain visible during the night or in the early hours of the morning when the sun is not yet out, thanks to a built-in wind up charger that powers the white LED headlight. Apparently, a single minute of winding the charger is able to net you 8 minutes of headlights, or the equivalent of an hour’s worth of flashing headlight and taillight – it is your call. Depending on the situation, you can also detach the headlight/charger from the bike mount while the charger performs its secondary function equally well as a cellphone charger, where it is compatible with selected Nokia, Sony, Siemens and Sony Ericsson handsets. You can purchase the basic model for £19.99, while one bundled with additional tips for different devices go for £24.99.
