A form of error message on the Xbox 360. The Red Ring of Death replaces the Ring of Light, the green circle surrounded the power button. The red lights indicate a sort of error message and the number of lights and placement of them mean different things. The worst would be three lights flashing, with the top-right not illuminated. In this situation, it means the 360 is suffering hardware failure.

Comparable to the Blue Screen of Death.
