What type of headlights must cyclists ensure visibility with while riding at night?

Cyclists are required to use standard bike headlights while riding at night to ensure their visibility to other road users. Standard bike headlights provide sufficient illumination to help the cyclist see the road and to make themselves visible to motorists and other cyclists. These lights are usually designed specifically for bicycles to be both effective and legal according to road safety regulations.

While high beams, LED spotlights, and flashing lights can enhance visibility in certain situations, they are not a regulatory requirement for cyclists or may not provide the appropriate type of light output for safe riding. High beams can be overly intense and blinding to oncoming traffic, while LED spotlights and flashing lights may not conform to the necessary specifications for continuous, stable illumination that standard bike headlights offer. It's vital for cyclists to adhere to these requirements for their own safety and the safety of others on the road.
