I have never felt the need to have the artificial sound of crickets, waves, or anything else to fall asleep or stay asleep. I really don't need any colored lights to sooth me into dream land either. I guess some folks need that sort of stuff though and if you are one of the Pure has a new audio device for you called the Twilight. The thing might actually be a pretty cool radio for a kids room.
The white dome on top of the radio hides a light that changes between several colors. The light can be white, blue, green, purple, red, or orange. It also has built-in lullabies for kids including 'twinkle, twinkle, little star' and 'rock-a-bye baby'. It also has a built-in FM receiver that will let you listen to your local stations and you can plug in an iPod or MP3 player via the aux input.
The Twilight also has a headphone port for private listening and it has a sleep timer that will turn off the music and the lights when you want I to. The snooze function is activated by touching the white dome and the alarm can wake you up with light as well with a dawn simulation. The Pure Twilight has an accessory for docking your iPhone or iPod and the price for the device is unknown.
