The new lights will be installed directly onto the frame of the bike and come on automatically at night, ensuring no energy is wasted during London's daylight hours. Santander is footing most of the bill -- roughly £768,000 of the £860,000 -- with the rest coming out of TfL's Cycle Hire Operational budget. London's roads can be dangerous for cyclists, especially in the heart of the city where traffic is most congested, so any additional lighting should be a boon to pedal-power enthusiasts.
