really? your RES stopped basking when the bulb got older? do you have a heat lamp aswell? mine will only bask when the heat lamp is on, and could care less about the UVB being on or not, or even working for that matter. and try both yellow and blue outlets, after i programmed mine i realized it was reverse of what i thought, so actually my stuff is plugged into the night time outlets and i've been too lazy to reprogram it since it works

let it go for 24 hours aswell, because if you set the timer AFTER it's passed the time it was supposed to happen, i don't think it actually does any switching of the outlets and leaves them both off, like if it's 2 pm, and you set it to start at 1:30 pm and end at midnight, it won't "magically" come on, you have to wait until 1:30 pm the next day to see if it worked or not. or just test it by setting it a minute ahead of the current time to see if it works and again, check both outlets after (night and day)
