One problem related to exterior lighting has been reported for the 1998 Mercury Mystique. The most recently reported issues are listed below.
Interior light harness just broke off and hit me in the head while I was driving. There was no applied force to the harness, and the force it hit me with caused me to momentarily loose control of my car. The part should not have been so cheaply built.
