Try swapping the headlight bulbs or buying a known good bulb and testing that way. Sounds like a shorted bulb filament issue.

If it was the front dash mounted lighter socket you used, the correct fuse is the 15A CIG & RADIO fuse (at the end of the second row) of the dash fusebox. If replacing the fuse hasn't fixed it, you may need to look closer at the wiring from the fusebox as it's likely the wiring has gone open circuit.
Take the fuse out and check for voltage at the terminals in the fusebox with the ingition key turned to the ACC position. One terminal or the other will have 12V on it. If no voltage on either you have a fusebox to ignition key wiring problem. Check for voltage on the ACC pin of the ignition switch, with the key turned to the ACC position. That's pin 3, a blue wire, of the 8 pin ignition switch connector. If still no volatge the switch is likely faulty. the voltage into the switch must be there as it also feeds the ECU and IGN systems, so the car wouldn't run at all if it wasn't.
There is another possibility. If you have an alarm system, immobilizer or turbo timer (assuming the GTT model) these devices could be interrupting the power lines and be the culprit devices.
I assume it wasn't the rear hatch area lighter socket you used, because the fuse for that doesn't power the radio or clock. The fuse for that socket is the 15A ACCESSORY fuse in the passenger side footwell fuse panel.

One wire is for the brake/directional filament and the other wire is for the tail light. The fixture should be grounded when it is attached to the bracket. To test which is which (the brown wire is USUALLY the ail light) make sure the fixture is grounded and touch a hot wire to each of the wires coming from the fixture. Watch to see which wire lights up the brighter filament and this is the brake/directional light. The dimmer filament if the tail light. Brakes lights and directional lights are both the same filament. Wen the brakes are applied, both lights are activated. When a direction light is turned on, it simply flashes the brake light filament.
