I found and bought a Rare AE101 maplight with sunglass holder.
In preparation for installation, I remove the ceiling then connect the 2 wires
of the maplight to the dome light. The result was the maplight bulb opens when
the door was open and close automatic when the door close [quite funny isn't it].
So I check again the wiring of Dome Light and trace the line which the the bulb
opens permanently even the door is close. One line was connected to the Dome light
and the other was connected to the body.
At last, the connection is successfull so I install everything.
Now I have additional lights and a holder for my favorite Sunglass.
