Strobe

Ignition timing light device has been obtained finding out to be a NOS(New Old Stock). Then how old is this American device, the switch to change voltages 6V and 12 insists the birthday was around 1970, for example VW Beetle produced prior to 1967 they had 6V lead battey.

High voltage by miswiring would do harm to the circuitry inside, so written on the caution lavel.

I hope this device would work well without any restoring troubles.
