Frequently Asked Questions (FAQs)

The 2005 RVLR amendment meant that it was now legal to have a flashing light on a pedal cycle, provided it flashed between 60 and 240 times per minute (1 – 4Hz). The amendment also meant that a flashing light was approved, meaning no other light was needed in that position.

2. Should rear bike light be flashing?

Your rear light should be red and ideally pulsing, and it only needs to be bright enough for other cars to see you. Your rear light only needs to be 50 to 100 lumens—much less powerful than your front light. Remember: it doesn't need to help you see, just be seen.

A 2005 amendment to the The Road Vehicles Lighting (Amendment) Regulations made it legal to use flashing lights on a bicycle in the UK. The regulations state that, if you choose to use flashing lights, they must flash at a frequency between 1-4hz, which is between one and four flashes per second.

4. Can flashing bike lights cause seizures?

Around five in every hundred people with epilepsy are photosensitive, or prone to seizures caused by flashing or flickering light. Both natural and artificial light may trigger seizures. Various types of seizure may be triggered by flickering light.
