WDW tends to avoid actual strobe lights or lights with consistent frequency of flashing (the kids of lights that are most likely to trigger seizures). Random lights like simulated lightning flashes or single flashes for pictures are not likely to trigger seizures, but I included them.
If anyone has any to add, please do.
This is a list of attractions I know of with light effects of some type:
MK
- Enchanted Tiki Room - periods of darkness with simulated lightning. The lightning is random and short.
- Pirates - some lightning flashes in the first dark part of the ride.
- Big Thunder Mountain Rail Road - there are no light effects in this attraction, but if you are riding on a sunny day, you will go in and out of dark tunnels repeatedly at high speed.
- Splash Mountain - on a sunny day, there are several places where you will go from dimly lit indoor areas to outdoor. The ride moves slowly, so the change is slow. There is a single bright flash when your picture is taken during the big drop.
- Haunted Mansion - almost at the end of the preshow, there is a flash of lightning at the top of the ceiling.
- Buzz Lightyear - just before the last room of the ride, there is a long narrow tunnel room with swirling red lights and flashing white lights. The swirling and flashing are not rhythmic.
- Stitch's Great Escape - Most of this attraction takes place in the dark, but there are some random light flashes at times (while looking for Stitch)
- Space Mountain - flashing lights
Epcot
- Spaceship Earth - the first part of the ride and the last part of the ride are dark, long and narrow.
The entrance 'tunnel' has screens high on the wall, warning that your 'time capsule' will turn and descend at some point during the ride. The screens are bright compared to the walls.
The exit tunnel has some lighting effects, but not flashes.
- Ellen's Energy adventure - includes a movie where parts are dark and then light suddenly appears (the 'Big Bang' theory of earth's creation)
- Mission Space - Includes a flash of light for a picture.
- Test Track - includes a light flash for a picture. Also, during evasive maneuvers test, your ride car will be in a dark area with bright truck lights suddenly appearing in front of you.
- Living with the Land - simulated thunderstorm. The first part of the attraction is dim; the second part is in a greenhouse, where the light can be a bit of a shock when you first enter. The ride boat moves slowly though.
- Soarin' - the end scene includes fireworks
- Journey into Your Imagination - Some flashes of light. One bright flash near the end where a picture used to be taken.
- El Rio del Tiempo (Mexico) - fiber optic fireworks in the ceiling and wall in the last scene
- Maelstrom (Norway) - near the beginning there is a spinning, pulsating light. It is irregularly pulsating
- American Adventure - the Chief Joseph sequence has a few stokes of lightning
Studio
- Star Tours - flashes of light during the attraction (you are in a space ship and end up in a spaceship fight)
- Voyage of the Little Mermaid - some flashing light, some twinkling lights and some pulsating blue lights above your head to simulate the top of the water. All are random
- Rock N Roller Coaster - one bright flash of light during picture taking
- Tower of Terror - one bright flash of light during picture taking. Elevator door opens suddenly to give a view of outdoors (so bright light on a sunny day). Some twinkling lights during the early part of the ride and I was too busy being scared and holding DD down to notice any more.
AK
- Festival of the Lion King - one act includes twirling flaming sticks
- Dinosaur - dark ride with sudden appearance of dinosaurs in front of you. Random flashes of light. One big flash as a picture is taken.
- Expedition Everest - includes some bright light effects
