Riding a bicycle might be safe during the daytime, but it might not be the same at night, especially if you are traversing some remote path. You need to have a way to inform others about your presence on the road. This is where the light emitting diode bicycle spoke light comes in handy.
You can affix them on the spoke of your bicycles. They can be set to continuous on or to blinking mode. Since they employ light emitting diodes, they consume very little juice and a single replacement of the battery will provide you with hours of light. Get one of them today, especially if you bike through low-lit areas. Costs $7.99
