i finally fixed my dash lights which i am happy as hell about! now when i was pulling stuff i found these two lightbulb sockets on each side. I dont know what these are for can someone tell me ?

Courtesy lights.

what does that mean

Small lights that provide a little illumination inside the car or somewhere else(under hood and in trunk usually).

The brackets should be under there somewhere that hold the lights

Those are what the brackets look like: http://www.camarocentral.com/1967_1981_Under_Dash_Courtesy_Light_Mounting_Bra_p/wir-305.htm

Put some bulbs I them and ground them out. They should lite up when you open the door. Should come on with the dome light.

any idea what type of bulbs this takes?

Download the Ames catalog. There's a chart with all the bulbs in there somewhere. Get the number for the bulb and head over to the auto parts store. They should be available.

I found similar light sockets behind the dash of my 69....one each side. Dont know why they had been hidden and not used but when connected and working, they look awesome at night with the door open

Sometimes if they are not grounded properly or if there is a problem with the door switches they will stay on after the doors are shut thus draining the battery. I suspect some people would just find it easier to remove the bulbs instead of taking the time to fix what's wrong.
