Flickering Light Bulbs
- Constant flickering of the light bulbs in a room creates the feeling of a ghost or an electrical disturbance, according to the Yard Haunters website. Lighting controllers are easily installed to vary the electricity run to lamps and light fixtures, creating a random pattern of flickering and dimming. Sound reactive devices can also be used to control the effect based on the wail of a ghost or the footsteps of visitors. Specialty light bulbs designed to flicker randomly can also be found, but they can blow in the middle of a movie scene or haunted house tour and usually have a very short service life.
Lightning Flashes
- As the thunder of a spooky storm rolls in, lightning should also flash. But creating the right split-second flash of bright light can be trickier than you think, especially when you want to align it perfectly with a sound effect. Wolfstone's Haunted Halloween website says that there are a number of sound-reactive lightning lighting effect controllers available that trigger a short, bright flash when a specific sound is heard. Some models feature direct wiring to prevent laughter or other sounds from setting off the flash. Anyone who is comfortable with electrical wiring and working with circuit boards can also create their own lightning controller.
