Holly- Visor

  The beast's green tongue rasped across her visor, sliming the lower section. The visor! That was it. Her only chance. Holly wormed her free hand to the helmet controls. The tunnel lights. High beams.

  She depressed the sunken button and 800 watts of unfiltered light blasted from the twin spotlights above her eyes.

  The troll reared back, a penetrating scream exploding from between rows of teeth. Dozens of glasses and bottles shattered where they stood. It was too much for the poor beast. Stunned, set on fire and now blinded. The shock and pain made their way through to its tiny brain, ordering it to shut down. The troll complied, keeling over with almost comical stiffness.
