To dream of headlights represents your level of awareness or how well you are paying attention to the “road ahead” in life. Trouble with headlights suggests a lack of awareness.
If you are driving in the dark without headlights it represents a lack of mindfulness. You’re unable to see potential obstacles or problems that may be coming up in the near future.
Example: A man dreamed that his father was driving in the dark without headlights. In real life he felt that his father was making hasty and irresponsible decisions with the family business.
