after changing bulb the light still doesn't work

I changed my gear indicator bulb yesterday but it still is not working. Can someone please tell me how to find out why power doesn't seem to be there? In case I'm not stating it correctly, this is the bulb under the gears that's to supposed to light up the letters at night (P R D 1 2) next to the automatic gear shifter.

Thanks to any who respond!
