How many times have you been under a car or in an electrical panel with a flashlight trying to point something out to another person? Today we have LED flashlights that also come with a LED Laser that you can use to point out specific areas of interest. I find this particularly useful when working in electrical panels or on machinery out on the floor. The one I have is a cheap one, the laser isn't aligned with the center of the flashlight, and you can't have the light and laser on at the same time. I still find it useful. Below are some links to different models I found doing a quick search. I have not used any of these but it's a good place to start to get an idea of what is out there.
