Lights - the rules
The road rules require riders to have a white front light and a red rear light at night or in conditions that reduce visibility.
Road Rule 259: Riding at night
"The rider of a bicycle must not ride at night, or in hazardous weather conditions causing reduced visibility, unless the bicycle, or the rider, displaysâ€”
(a) a flashing or steady white light that is clearly visible for at least 200 metres from the front of the bicycle; and
(b) a flashing or steady red light that is clearly visible for at least 200 metres from the rear of the bicycle; and
(c) a red reflector that is clearly visible for at least 50 metres from the rear of the bicycle when light is projected onto it by a vehicle’s headlight on low-beam.
