The Nite Ize SpokeLit Rechargeable with Disc-O Tech is a bicycle spoke light that gives you strong side visibility when riding in low light. Slide it between your spokes and it wedges in place without tools; it fits most bicycle wheels. The Disc-O Tech module lets you choose red, green, blue or white and set each colour to glow or flash, or leave it in colour-changing Disc-O mode. A memory feature remembers your last setting, so it comes back on the same way with a press of the centre button. The housing is weather-resistant, and the light recharges in about 2 hours with a micro USB cable (not included), giving about 5 hours of run time. One light per pack.
