The two tailights in the trunk of my 2005 honda civic si do not work. the bulbs and fuse are ok. is this a civic problem

Do the lights on the trunk operate when the parking lights are on, but do not light up when you apply the brakes? If so, this is normal. Only the outer red lights are brake & parking combination lights. The ones adjacent to the reverse lights on the trunk lid are parking lights only.

If the red lights in the trunk lid are not working at all, check the red/yellow and black/silver wires where they go from the trunk lid down into the right side of the trunk area. The wiring harness for the parking and reverse lights are contained in a piece of black tubing that is connected to the passenger's side trunk hinge.

I hope this helps! Good luck!
