How do I get to this bulb…? Help!

@Roux
Are the connections easy to spot? Do I need a long extension to reach them? I see a nut on some threads going through the metal panel, but that’s about it. Also, I’m using Diode Dynamics LEDs—they’re supposed to have built-in resistors to prevent flickering. Guess I’ll find out when they get here! Thanks for the help!
