Narrative:

Upon landing at lbe copilot/first officer flight instrument lights went out. Seconds later 2 plumes of brown smoke were seen rising out of the copilot/first officer defroster vent. The first officer advised the captain of this and in response the captain took control of the airplane and promptly taxied the airplane clear of the runway to the nearest exit taxiway. Simultaneously he advised the tower he was going to evacuate the 6 passenger on board on the taxiway. He stated that he believed there was a fire in the cockpit and that the fire trucks should be dispatched. There was no fire and nobody was injured in any way. The aircraft received no fire damage -- the only sustained damage was subsequently discovered to be a couple of chaffed wires. No incursion with any aviation traffic was involved.
