Wacky Wednesday: Pen Light

This wacky Wednesday, my new invention idea is the pen light! I've noticed as a writer that if I write in the backseat of a car at night time, and it becomes night time at like 5pm here, I have to struggle to see what I'm doing, or I have to turn on the bright overhead light and that is dangerous. This would be a small LED light that would be towards the tip of the pen, so that you could see what you are writing. In theory it could just be a mount that you put on a normal pen, so that you can write with your favorite pen. It would work as a sort of headlight. The band could be made of a flexible ring that wraps around the end of a pen. They can also be used in case of an emergency. Plus, this less amount light allows the driver to not be as distracted.
