Abstract
Some conclusions: -In lit streets, low-beam headlights contribute little to the visibility of objects, cause glare and can obscure direction indicators. -Presently, it is feasible to adapt the existing vehicle lighting such that it will be characterised by a minimum of about 100 cd in a direction straight ahead. The spatial light distribution required further consideration. -Inherent in the introduction of the improvements is an improvement in road lighting for very poorly lit roads with an important function for the road traffic. -Further information is needed regarding to the quantified values of costs and benefits.
