I use a app called ColorID on my Blackberry which changes the color of the LED and flash pattern, etc. I use it for when I am On-Call and it flashes a different color when calls & emails come in from work. I asked them about whether they had a Android app, and got a quick reply that they were working on it, but not all Phones have LED. Shocker to me, I just assumed all modern phones had a LED. So, does the Dell have an LED or are they other applications that do something similar, like flash the whole display or something?
