Neat vintage multi-purpose battery operated light. REQUIRES 4-D Cell Batteries. I did test it out and the switch is very tempermental. Sometimes if you let go of the chain after it turns on it will stay on, but usually if you pull the chain more it will turn off. Does not put off much light compared to the newer stuff, but would look period correct in a vintage trailer. (Maybe someone can cut out the internals and replace with a newer LED?? Original box does not have a date, but it looks to be mid 1980's to me since it does have a UPC. The lamp is about 6.5" x 4.25" x 3.5".
