EDIT: While I'm in here, I might as well try to make the RESERVE light work on the fuel gauge work, too. Should it come on initially like in my 300D when the key is turned to position #1? What watt bulb is that tiny thing?
Thanks!

Yes, that confirms that the circuit is functioning, so, you can forget about any fuse or rheostat issues.
Your problem is the bulbs and/or the sockets.
The reserve light doesn't work because of the accumulated debris on the fuel sending unit.........most likely..........and you'll have to remove the rear seat and pull that unit (need a big socket) and clean it with Brakekleen. That will restore function of the reserve light.
