Roller Coaster Lights question

Are all the roller coasters and ride lights on timers or do they get turned on and off by employees, because it seems like long after the roller coasters are closed the lights are still on?

Man, I hate the offseason.

Most of the coaster's lights are on a timer and remain on for most of the night. The only lights that i had to worry about at Blue Streak were the station lights. The other ones were located on a timer under the lift.

Dragster's lights turn off at 3am. I sometimes amaze myself at how much I actually know about these things.
