What may be the effect of wrong adjustment of low-beam lights?
aIncreased fuel consumption.
bDeterioration of road visibility at night.
cIncreased light bulb consumption.
Why?
Incorrectly adjusted headlights may illuminate too little of the road ahead or direct light away from where it is needed. At night, this reduces visibility and makes obstacles harder to spot early. Headlight alignment itself does not increase fuel consumption or make bulbs wear out faster.
