I have used Volvo P80 dome lights for sale. They are used in working condition. These are old, old and sometimes the switches do not work properly. I tested mine and if they work 100% and have the mounting tabs they are A grade for $95. If they have any issue like broken mounting tab or lights don't work quite right they are B grade for $75. Light will come with lens.
The part number on your light in on the underside of the light. If you want a perfect match, or certain color, etc., select the proper part number.
