The purpose of the exterior lights on a semi-truck are safety.  When the lights are out or not working properly it opens potential for harm to the driver and other vehicles around them.  One of the biggest reasons for lights that are not working or are flashing off and on is a loose connection between the truck and trailer.  The probability for such a connectivity issue is only increased by adding additional trailers.

By not having the plugs tightly and securely plugged into the receptacles with little to no wiggle room you are opening the door for issues.
