An Invention the World Needs #2 - Intelligent Lightbulbs

So often I try flipping the lightswitch only to be greeted by a startling flash of light and then back to darkness. My lightbulb blew out. What would be nice is if the lightbulb could change colors prior to blowing out (say within the last 5 hours of life, it produces a reddish tinge), so that I know to change the bulb before it expires. This way, if the lightbulb blows out as I stumble home at 2 in the morning, it'll be my fault and not the lightbulb's.
