The car on the background is a 1993 silver 190D with class interior (you have a trained W201 eye).
The best way to get the dash cluster bulbs replaced is to start with removing the lower dash panel (5 screws and one (plastic) nut in total). Remove the plastic outer vent hose and additive piece at the side of the heater house, unscrew the speedo cable and push the dash cluster to the front (from the back). Personally I prefer this method to pulling the dash cluster with hooks.
When the dash cluster is pushed to the front, you can take off the plugs and connectors and replace the bulbs with new ones.
