Q.No.149: - From your experience in watching cars on the roads at night, are automobile head lamps connected in series or in parallel?

Ans: - The head light of cars are connecting in parallel because their brightness are approximately same. If they are connected in series then first light will be brighter than the second light. In series potential will drop in both headlights. While in parallel potential will remain same and they will have same brightness.

Head lamps of automobiles are generally wired in parallel. This way, if one headlight is to burn out the others remain switched ON.
