Is it possible to put a light on a timer? Not just to turn it off, but to dim the light a slight bit? to dim it every few minutes?

OR

When light1 is on for a certain amount of time, it will turn off;
then light2 will turn on.. then after a certain amount of time, it will turn off;
then light3 will turn on.... etc etc etc until say.. light 10 turns off and light1 turns back on?

np, just use a dod_round_timer. set it to not be visible, set the time, and have it trigger your light.

you could also set up a trigger multiple in a spot that people will be sure to run through often. give it a delay of however many seconds and have it trigger your light.

afa dimming a light, I don't think its possible. but what you could do is put 2 light entities right next to each other. turn one off and it will appear that the light dimmed.

try this for your sequence lights:
trigger1 --triggers light1 , multi1, multi2( with say 10 sec delay).
multi1 triggers light1, 2, 3, ect, on with time difference of whatever you set.
multi2 triggers light1, 2, 3, ect, off with time difference of whatever.

you could also have multi2 trigger trigger1 to go off again at the end to keep it all repeating.
