Three Dunedin organisations are getting together to promote cyclist visibility as winter days grow short.

Staff from the Dunedin City Council, Sport Otago and the police will be stopping cyclists this week to survey them on what they know about the legal requirements around the use of lights.

The work is part of the Be Bright campaign, which is promoting visibility, an essential part of cycle safety.

The initiative includes the council giving away free reflective strips, and Dunedin bike shops offering discounts on bike lights.
