In good driving conditions the HEADLAMPS in the average car enable the driver to SEE for about 100 metres on an unlit road and for about 30 metres on dipped headlamps.
Badly adjusted headlamps are DANGEROUS and will limit the range of vision and may dazzle oncoming traffic when dipped.A well lighted vehicle will be CLEARLY VISIBLE to other road users.To be effective lamps,reflectors,number plate lighting and indicators must be kept clean and in good working order.
