Do bicycles need working lights after dark in Northern Ireland?

Yes. Between sunset and sunrise, a bicycle must display a lit white front light and a lit red rear light.

Highway Code rule 60 also requires a red rear reflector, and amber pedal reflectors on bicycles manufactured after 24 January 1996. Flashing lamps are permitted, although a steady front light is recommended on roads without street lighting. Reflective clothing alone is not a replacement for the required lights. Check batteries or charging before travelling home after dark.
