What lights and reflectors does a bike need in Denmark?

Lights for the dark, reflectors all the time.

Short answer

When you ride in the lighting-up period (lygtetændingstiden), a bike in Denmark must have at least one front light with white or yellowish light and one rear light with red light. The light must be clearly visible from at least 300 metres and also from the sides. Flashing lights are allowed if they flash at least 120 times a minute. The bike must also have a white reflector at the front, a red one at the back, two yellow reflectors seen from behind that move as you pedal, and a yellow reflector on each wheel, or white reflective tyre or rim sides.

Why

  1. White or yellowish light at the front, red at the back.
  2. Flashing lights are fine at 120 flashes a minute or more.
  3. Reflectors are needed on front, back, pedals and wheels.

Details

Lights must be fixed to the bike so they do not change direction while you ride.

Tip

If you use clip-on lights, mount them firmly so they keep pointing the right way on bumpy streets.

What may differ

Cargo bikes and bikes wider than 1 metre have extra rules on where the lights sit.

Common misconception

A flashing light is not allowed on a bike in Denmark.

What actually happens

Flashing front and rear lights are allowed if they flash at least 120 times a minute.
