Bulb finally blew on my snap on test light after about 5 years, figured I'd order these and see if they're compatible and it works. Cheap and easy replacement, and now I have a stock just in case another bulb fails.

My Craftsman test light Sat useless in my toolbox until I found these. I have no idea how long they’ll last but my test light has value and functionality again!

This worked fine. I bought to replace a bad one in my old snapon test light that had been in there since 1995. Had to dig the old one out but after doing so this went in and after a top cable adjustment it works flawlessly. The red light from this is kind of cool. It looks something like a neon light. The original was just regular. Serves it's purpose just fine though and if I ever use up the remaining 9 from this pack I would buy it again.
