The red lights are unnecessary. Most turts stay in the water when they sleep, so they're plenty warm.
Leaving the lights on all the time will throw off their system (imagine if the sun stayed out 24 hours; you'd be pretty messed up).
You can either try to have someone turn off the lights for you or get a timer that turns it off automatically. (link below)

Also, they should have lights on for twelve hours a day similar to the sunrise/sunset in your area. For me it's lights on at 8a and off at 8p.
