problems w/ House of Haunted 2 map

[Confuzed_Person]

ok, im makin a house of the haunted 2 map, and i jus started it. im workin on a new way to make it more realistic and having pylons work as lights. now if u enter the location the light will turn on, that works fine. but once u leave the area, after 10 seconds the lights are suppose to turn off. now i did it by makin u have vision w/ player 8 (yellow) and no vision w/ player 7 (white). and when u enter the area the white pylon changes to yellows. jus doesnt turn back. ive checked the triggers and i made sure that when they turn off it goes,

Effect: Travelers have exactly 0 units in x location.
Condition: Give units owned by player 8 at v location to player 7.

If the pilon-light (owned by default by P7) is under location X try this:
Condition: P1 brings 1 <unit> to X;
Action: Give 1 pilon owned by P7 to P8;
Preserve trigger.

And to swich it back:
Condition: P1 brings exactly 0 <unit> to X;
Action: Give 1 Pilon owned by P8 to P7;
Preserve trigger.
