Lighting is very important for seeing and being seen. Each light must illuminate in a specific way; for example, the dipped headlight must illuminate a sufficient distance without dazzling other road users. If it is not properly adjusted, it could dazzle others or we might not see a sufficient distance ahead. That is why we must check the lights frequently.
