dimmer switch for dashboard 90 Camry wagon

Okay having no luck in getting a new switch, napa ordered be one, not what I needed, think it might have been for the headlights. So then I found one on Ebay, photo showed it was exactly what I had. Switch came, the guy sent me the wrong one and then couldn't find the one I bought, gave me a refund. Is there anywhere online to find these? Am I calling it but the correct name? Any help would be appreciated. Can't get the car inspected until I have the dash lights working.

Light Control Rheostat

Thanks!
