It's a UV flashlight. I used it to try and identify an A/C leak in my jeep engine bay after putting some dye in the system. You can adjust the beam to be focused which is nice for aiming at hard to reach spots, like underneath all the hoses and lines. It's also fun to look at things like credit cards with it which have hidden logos that pop up under UV.
