Two of them are "lamp out" sensors. One is the headlamp out sensor and the other is the tailamp out sensor. I beliebe the "gazebo" is actually a radiator...for the low coolant level warning lamp. You might want to start with checking the battery, check battery connections to make sure they are clean and tight and check the charging system output voltage and, of course, the coolant level. Also, check the tailamp bulbs for mushroomed contacts and the bulb sockets for pushed in contacts or corrossion.
