What kind of simple machine is a reflector on a bicycle?

Answer 1

If you want to ride after dark in a legal manner you need:

- a white reflector facing front

- yellow/orange reflectors facing sideways

- and a red reflector facing rear

Depending on location, you may also be required to use lights, usually white forward and red backwards.

Reflectors on a bicycle are used to provide for rider safety. People who ride bicycles near automobiles use reflectors in a similar manner to headlights on a passenger vehicle. Different jurisdictions have differing requirements for reflectors on bicycles.

Answer 2

A reflector isn't a simple machine at all.
