The reflectors on your bicycle illuminate when a light is shone on them, directing some of the light back to the source. In poor lighting conditions, if an oncoming vehicle has their lights on, the reflectors may help the other vehicle see your bicycle. Reflectors are an important part of your bicycle’s safety equipment. Do not remove the reflectors from your bicycle. Read the Warning About Mechanical Work before performing any service work on your bicycle.
Every three months, make sure all the fasteners holding the front, rear, pedal, and wheel reflectors are tight. Check that front and rear reflectors are oriented so their reflective surfaces are perpendicular to the ground, and that all reflective surfaces are clean and in good condition. The front reflector should point directly forward, and the rear should point directly back. The rear reflector should be at least three inches below the top of the seat.
To adjust the position of the reflectors on the handlebar or seatpost, loosen the clamp screw until the reflector mounting bracket can be moved. Reposition the reflector, and re-tighten the mounting screw.
To adjust the position of a wheel reflector, loosen the screw, reposition the reflector, and retighten the screw. For reflectors that are attached without screws, apply slight pressure on the reflector until it can be slid along the spoke.
