Light Rail Replacement Battery Includes:Comes with a Light RailThis is a user replaceable Lithium Ion battery for the Light Rail bike light bar. We believe in a customer's right to repair. While we've taken care to design the Light Rail to preserve the longevity of the battery, it's still a part that will eventually degrade under normal usage. The factory installed battery should last for several years of heavy use, but be prepared for anything with this replacement that you can easily install yourself.
