Portable Generator with Quartz Lights (C/N)

When Robert Muldoon and the workmen went to repair one of the downed fences that was caused by the Tyrannosaur, they brought a portable generator with them. The generator was apparently an older model because it sputtered before it worked fully, and it possessed telescoping arms, at the ends of which were quartz lights. The generator was intended to provide power to the power saws and other equipment they might need in order to fix the fence.
