Replacing dash light bulbs

Originally nether the ammeter/temp and the speedometer lights didn't work and seperately the gear indicator didn't work. I cleaned all the contacts and made sure all grounds were good and now all the lights work perfectly! The dimmer/rheostat works like it should as well. Even the radio and fan toggle lights work with the dimmer.

I guess I just had some loose connections, I'm happy it's all fixed, getting the car inspected this week, should be driving in pretty soon! Thanks for the help!
