Correct answer

  • CSí, porque las luces pueden desequilibrarse por diferentes motivos.Yes, because the lights can go out of adjustment for various reasons.
Explanation

Headlights can go out of adjustment because of potholes, knocks, bulb changes or changes in the load, and then they dazzle others or light up the road less well. That is why you should check and adjust their aim regularly, although you do not need to do it every time you set off.
