This Antique Automotive Trouble Light is in Very Good Condition. I have no way to test it but it looks to be in really nice shape. The filament in the bulb is intact. It says it is a GE 6-8 volt. This trouble light has an interesting clam closing cover on the light bulb. All the wiring is in great shape. This looks very old, probably 6 Volt. Maybe from a 1930's car or truck. Thanks for looking.
