How many parking lights are required for a vehicle to pass safety inspection?

For a vehicle to pass safety inspection, it is required to have two parking lights. This requirement ensures that the vehicle is visible to other drivers when parked or stationary, particularly in low-light conditions. The presence of two functioning parking lights enhances safety by providing a clear indication of the vehicle's position, helping to prevent accidents. Furthermore, having two parking lights also adheres to standards set forth in traffic safety regulations, which aim to promote safer road usage for all users. Thus, meeting this requirement is crucial for a favorable inspection outcome.
