I reckon that different versions of the Extreme have different front panel setups. Mine has three lamps above the LCD display. One for the fan, one for the timer, and one for the heating element. There is also a larger round hole to the right of the display, and that's for the remote control IR detector. The red heating element lamp lights when power is applied to the heater. I can see how some might find the flickering of the red lamp distracting when the controller is cycling the power to the element to maintain the set temperature. To me it makes sense to have that lamp do what it does -- that's how I'd set it up, too. But then I'm an electrical engineering geek and having a visual indication of when power is being applied to the element is interesting. But not everyone cares about such things, so a simpler "idiot lamp" approach, where a lamp indicates "not ready/ready," could be good too. It buffers the user a layer farther away from the actual operation of the device, but it's not as geeky. Designing the human interface is an art in itself. Trick is deciding what kind of human to design for: those interested in the workings of the thing, and those who don't care.
