to the accident. He testified that the bulb was in "cold shock," causing the filament's brittleness. Because of the brittle state, Mr. Doyle opined that the filament breakage resulted from the impact when the bulb hit the water as opposed to the force of the accident. He contrasted this to an illuminated bulb's condition, indicating that its heat would have caused the filament's pliability.

Mr. Leonard C. Adams presented results of tests he had performed at the behest of the plaintiff. Upon his visual inspection of the bulbs in question, Mr. Adams found bending of the filament support posts, upon which he based his opinion that this bulb would have been illuminated at the accident time. He was unable to state, however, that the loose filament in the bulbsupported a conclusion that the bulb had been burning at the time of the COALINGA's impact.
With a supply of new light bulbs, Mr. Adams performed acceleration and impact tests to reconstruct these forces' effects on a bulb. He never measured the precise amount of force used and only presumed that the similar bending of the filament posts resulted from a similar impact. Despite Mr. Adams' attempts to duplicate the accident, the Court cannot find that his experiments can establish that the bulb was shattered by the impact of the collision and had been previously burning. This is in view of Mr. Adams' exclusive use of cold bulbs, the distinction between a bulb's filament and its filament support posts, the latter which do not burn, and testimony that support
