Need help with auto-battle with a timer.

[Tanarex]

I can't remember how I did this before, so here I am. When you enter the sewer system I have a timer that starts at 10 seconds. At the end of the timer, you get attacked and an auto-battle starts. At the end of that battle, the timer starts all over at 10 seconds. Wash and repeat. Now the only way to stop the attacks is to light beacons. You light a beacon by clicking on it and it will reset the timer to 10 seconds. You then have enough time to reach the next beacon before time runs out. You can complete the entire dungeon without triggering an auto-battle. The problem I have is that when time expires on a beacon I want it to become unlit and ignitable it again. Thereby giving you a chance to use it again. With every beacon but the latest, one becoming unlit. So I'm trying to figure out which switches to use on the beacon to make that happen. I've added screenshots to show you what I'm doing.
