Make sure your lights, indicators, reflectors and number plate lighting are clean and in good working order so that you can see clearly and be seen at all times. A clean windscreen is also important when driving at night.
D rive at a speed that allows you to stop within the distance covered by your lights. Assuming good driving conditions on an unlit road, the headlights of a typical car let you see for about 100 metres. Dipped lights will let you see for about 30 metres and a car travelling at 100km/h will cover this distance in approximately a second.
Keep your headlights adjusted properly. If they are out of line,they are less effective and may dazzle oncoming traffice, even when dipped.
Even with the best headlights, you can see less at night than during the day. Pedestrians and unlit bicycles are extremely difficult to see in the dark, particularly if you have to deal with the glare of oncoming lights.
