There's these pens that have a stylus and flashlight built in. I thought they were amazing. Great to leave in cars to write stuff down, and you have a flashlight if you need to check anything. I have a few from clients who customized it with their company logo and info.

I think you can get a no name one for cheaper than $15, but I have no idea where to find them.
