Several posters have mentioned Craftsman timing lights. I had one that I purchased in 1971. I purchased it for entertainment only . . . didn't use it professionally. Put it aside around 1975 and didn't touch it until two years ago.

Hooked it up and it didn't work. Looked thru my paperwork and found the original receipt *AND* the lifetime guarantee on the bulb.

Took it to the nearest Sears store. They no longer made the same model so upgraded me to a better model with inductive pickup. No charge, no BS. Kudos to Sears!

The new one came with a limited warranty . . . don't remember how long . . . probably a year.
