This is a timing light. it is used to tune a car engine. It makes sure the spark fires at juts the right time at the during the compression stroke. I still have one of these but have not used it in many years. Cars have electronic ignition that it more accurate and reliable.
I enjoyed some of your guesses. I think it does resemble a heat gun.
Thank you for playing.
