Night Riding

Rider's vision at night is supported only by headlight and street lamps - hence, visual information is limited.

Increase margin of safety by controlling speed. Use high-beam/ low beam from time to time to maintain visibility. Do not look directly into the headlights of oncoming vehicles as this causes temporary blindness.
==========================================================
Dangers beyond visible areas

Information about road situations are limited at night time. Parked cars, bicycles without headlights, pedestrians with dark-colored clothes, gravel/ sand on the road are practically invisible in the dark. Reduce speed whenever visibility is poor. When there are no oncoming vehicles, high beam may be useful in getting more road information even on familiar roads.
==========================================================
Always be careful about temporary blindness including the evaporation phenomena at night.

To avoid temporary blindness, do not look directly into the headlights of oncoming vehicles - including those behind you through the side and rear-view mirrors. Also, be wary of the evaporation phenomena where spotting pedestrians between headlights (yours and that of the oncoming vehicles) is difficult.

Night time visibility distance test by color (Front Headlight at Low Beam)

Drastically improve visibility by using reflectorized materials.

Survey results show reflectorized materials are more visible than white color.

Reflectorized materials are 3x more visible than black.
