I noticed the selftimer light is a pretty bright light too bad on the t2i its red, but i donno some might want to try filming with a red light as its better than nothing , but I remember certain models I think it was the 7D which the light was white instead of red. On some of the camera's they can use it for focus assist and it quite bright. I am unsure which color it is on other models than the t2i. But I wonder if it is possible to switch that LED light on the front of the camera on to use as a light source. You never know it might be useful or handy to have as an option.
Also that feat was removed (and it was not good for shooting)
