Messiah Entertainment offers the darklite integrated lightbar for the Sony PS3. The lightbar gives your Sony PS3 blue light effects similar to what car enthusiasts mount under their pimped out cars.

The PS3 lightbar (see photo below) is designed to look like an original part of the PS3 console. The blue light LEDs can be dimmed. The Playstation 3 Darklite Integrated Lightbar sells for $14.99 on Amazon.com.
Messiah Entertainment also offers a more useful Sony PS3 accessory with the Darklite Blu-ray Remote.

The remote comes with a docking station that charges the slider style remote. Backlit buttons make it easy to use it in the dark. The PlayStation 3 Darklite DVD Remote sells for $29.99 on Amazon.com
