When are divers allowed to use only the parking lights while driving?

Divers must always adhere to the legal requirements for vehicle lighting, which dictate that parking lights are not substitutes for established driving lights in any situation where visibility may be compromised. Parking lights are intended for stationary vehicles to increase their visibility when parked, not for use while in motion. Consequently, using only parking lights while driving is prohibited at all times, ensuring safety and compliance with traffic regulations. This highlights the importance of using proper headlights or taillights to ensure that drivers are fully visible to others on the road, regardless of the time of day or weather conditions.
